I`m sure i read somewhere that 90% of the automotive paints in the USA are manufactured by the prison service using prisoner labour. I have no problem with penitentiaries making paint but it worries me that they don`t have the vision to provide the colors people want or need.

I`m reasonably certain that Dulux paints are standard oil based products using mineral turpentine as a solvent. What do the EPA recommend as an alternative?

Any chance the Donald could be persuaded to declare war on the EPA and leave the rest of the world alone for a while?

No Dulux here Bob. EPA said if we kept spraying it we would burn up from climate change,, or was it freeze to death???? Cant remember.

They probably can't remember either or had to change it when the predictions went the opposite way to reality.

I believe he has Bob.
I was reading something the other week about him wanting to dismantle the EPA and there were a whole bunch of moaning zealot greenie leftists saying he was against clean water and air and encouraging toxic dumping in rivers and the usual complete and utter fabricated crap.

I think what he is against and recognises is how over the top they have gone with things.  I read they have or were going to ban model airplane engines because of their emissions. Yeah, I'm sure all the nasties all those 1 and 3.5cc model airplane engines put out are a real significant factor in the smog and pollution not only in the states but in the whole global total.   ::)

I believe they also had Lawnmowers and brushcutters in their sights too because they were turning the air black with the vast qtys of emissions those little engines were pumping out.

There is a hell of a difference between wanting to reel in an entity gone mad on it's own self importance and power tripping that is stifling the country economically and otherwise and trying to encourage Illegal toxic Dumping in waterways!  ::) ::) ::)

Was this the one on Craigslist just outside Austin?

Yes, it was.

Ok, I have been reading the ST2 manual all week and have come upon the "ST2 Builds and Accessories" section. This explains the original option the engine came with from the factory. My build number (A28) says this:

Marine auxiliary triple survey, clockwise rotation, close coupled fan shroud for raised hand starting and with starter blanking plate. Long running/sump heater crankcase. Standard flywheel with starter ring. Fuel pumps set to no overload.

Governor set to 2600 rev/min
Governor range 1200-2100 (outside 8% governing limit)
                                2100-2600 (within 8% governing limit)
                               
Can someone interpret that for me?

Can someone interpret that for me?

Here's a layman's thoughts

"marine auxiliary triple survey" probably just means it was intended to be used on a boat, but not necessarily as the engine that powered the boat but one that ran a generator or lighting, or other systems - and maybe that it was subject to "survey" in that there were rules governing its safe use in marine circumstances & maybe around it's maintenance schedules to keep it reliable so it didn't break down out in the middle of the bloody ocean

"clockwise rotation" is, well, clockwise rotation of the crankshaft when viewed from one particular end (and that doesn't matter to you, probably, cos it will only run in the way that makes the fan work properly to push air over the motor?)

"close coupled" usually just means something that is attached to the end of the crankshaft and driven (in this case the fan) as opposed to being driven by pulleys and a belt

"raised starting" maybe just means the design of the fan housing leaves room for a hand-crank handle as it doesn't have an electric starter motor

Which would be why it has the "blanking plate" over the hole where the starter motor would otherwise be?

"long running sump and sump heater crankcase" probably refer to the oil capacity of the sump (big sump = tolerance for a long run if no-one remembers to check the oil or if it isn't turned off for weeks at a time, maybe?) and maybe the oil system has a heater such as is common in cold climes so the whole goddamn motor doesn't freeze and seize? And so oil will flow on startup in cold temps, maybe?

"Standard flywheel with starter ring" (ring gear) suggests if you took the "blanking plate off you could probably fit a starter motor?

"fuel pumps set to no overload" might be something to do with the combination of the size of the element in the pump and the movement of the rack?  Possibly set up so that the motor can't get enough fuel to hurt itself?

Other, better-informed folk will chime in here . . .

Close coupled means the driven equipment ( generator, pump etc ) can be run off the engine shaft as in the case of cheap single bearing alternators that  have one bearing in the alternator and rely on the engine shaft for support the other end.
As such it is likely the alternator you have is or the original was mounted to the engine itself rather than having 2 bearing and the ability to be belt driven for instance.

Fuel Pump set to no overload.
Usually industrial engines have a power rating for Continuous  output  ( 12/ 24 hr) and a higher rating ( usually 10%)  for a given time ( generally 1 hour) for which they can be " Over driven" above their  normal continuous output.  Your engine is set to have Continuous power rating only.  Easy fixed, adjust the throttle limit screw if you want more but on a genny, probably not the best Idea to screw your frequency and potentially voltage outputs.
Other engines sometimes express this as RPM ratings  @ say 3000 and 3600 Rpm.  While they do 3600 rpm, they are not meant to do it continually.... although the Chinese manufacturers tend to leave that fact out the manuals.  Big numbers sell after all.

My understanding of Raised hand starting is the engine must be mounted/ raised to be hand started.
IE, if the engine was sitting flat on the concrete floor, you would bust your knuckles on the cement as you tried to crank it because the starter handle would not clear..... or at least your knuckles wouldn't.
My horizontal Cyl China engines are like this.  Worst thing is to Mount them on 50 mm timber bearers and realise  the clearance needed for your knuckles is 55 mm.  If you go to hand start the thing,  make sure you have PLENTY of clearance on the downswing.

Long running sump generaly means extended times between shut down for checks, in this case the oil level. As all engines burn oil, by adding a larger sump you have more capacity for longer run times between top ups.  And the oil will stay cooler, less foaming etc.

 It can also mean that the sump is of an uneven design such as found in a lot of cars where it is deeper behind the Cross member.  With this term also goes to the fact the PICKUP is a long runner meaning it is not under the oil pump but rather has a long extention back to the deep part of the sump.
Small block Chevs tend to have a short pickup that comes out from the pump and pretty much straight down  but depending on the application, they may have a long pickup if the sump is located to the rear of the engine rather than the front.
The term as I know it also applies to Dry sumped engines  meaning the oil resivour can be remotely located rather than right near the engine.

Thanks again for all the replies fellas!

I think I found what "Raised hand start" means:



Which would be really neat if I had all the parts!

I still haven't been able to start the engine since I have had it here at home. I hope to get a battery and fashion a fuel tank to get it started today. I'd really like to fine some sort of air filter to cover the intake first tho.

Well, I got out today in the lovely Texas heat and tried to get it started again. I hooked my truck battery to the started with no luck. The solenoid is rusted all to crap and stuck. SO, I pulled it out by hand, and tried it like that. It turned the engine over for a sec, then stopped. Seemed like the battery ran out of grunt. I tried starting it by hand, but it is next to impossible. (I ripped a chunk of skin off my hand trying it). I did get it to turn over, and it was puffing black smoke, but I couldn't get it to catch and run by itself. Its either going to take a much stronger 12v battery, or a 24 volt system.

So, I decided to check the wiring on th eterminals coming from the gen head. They seems ok, so I hooked the battery to it, and tried the starter switch. It clicked, then buzzed for a second, but that is it. I'm almost positive that portion is 24v based on what you all have said and every video I have seen on youtube.

I'm still having trouble putting together in my mind how applying 24v to the gen head will turn the motor tho!

Also, is there a reason why my engine is so hard to turn by hand? It seems everyone on youtube can turn theirs fairly easily. Mine is almost impossible to move. Is it becuasue of the load the gen head puts on the engine? What can I do to make it easier to turn by hand or is that a product of a full rebuild and lube?

the gen and verify first the engine issus it must run good by hand decompressed. and it must start with 5/6 smart turns. after that think finaly the electric start and gen. pedrosa

Check the valve clearances and then adjust the decompression levers as per the manual. Could be the pistons are coming into contact with the valves or that you are trying to overcome compression while cranking.

The SOM drawing I posted  requires 24 volts for an ST2, 12 volts for ST1

If it has stood for a long time without an air filter or exhaust there is quite likely some surface rust in the bores. Just behind the decompressor levers there are two nylon plungers, lift these out and fill the two small cylinders with engine oil. Replace the plungers and push them all the way down. This will pump oil into the combustion chambers, lubricate the pistons and increase compression for cold starting.

Are you cranking it the right way? Some cranking handles can work in either direction. If you are cranking the wrong way the engine will blow air out of the air intake and suck through the exhaust.

Yes he started it with a battery connected to the starter directly. I didn't pay attention to what kind of battery, but it appeared to be a car battery. He was a heavy equipment mechanic tho, so it could have been a heads duty one.

I'm definitely turning it the right way. Direction is on the handle and only turns that direction. I figured it was just or crud from sitting for awhile.
