This thread and not having the inclination to Muscle round the Roid to balance it, made me Dig out my little China Horizontal today.  As soon as I got it out I remembered the biggest drawback with the thing was that Damned Pulley.  I was thinking about trying to find some plate and get my brother in law to centre it up for me on his lathe so I can weld in a shaft and get him to put a 3/4 and 1" step in it.

I have some large faceplate like things off a lathe that I picked up from a scrap bin outside of a machine shop that are probably heavier then the original flywheel. I might talk to him about what these would need to bolt up to the flywheel and put the shaft on one of those.
Might be better to go somewhere and have them done, he's a fine machinist but I'd be lucky to get the things back by christmas....... next year.

I looked on some China engine sites and the only thing I found for those engines is the original flywheel and pulley. Not much good to you.
perhaps having a plate and shaft made to fit may be the easiest option for you?

While looking, I noted the starter motors on some slightly smaller machines.  They were .7 KW.
Seems that even if your starter is double that, it shouldn't pull massive amounts of Current.  The starter on my Merc was 3Kw and the one on my truck is only 2.7 and normal batteries and cables spin them up just fine.

Of course being a new engine everything is going to be tight so that may have an effect on the cranking effort.
My little engine hasn't got a great deal of hours on it but trying to turn it over today without the compression release was impossible no matter how slowly I tried to turn the flywheel and let the compression escape through the piston rings.
As I suspected might be the case, the injector pump was stuck, again, so I pulled that all apart, cleaned the gum out and got it firing again nicely. It was well and truly stuck this time and it proved hard to get apart especially the main plunger but all good now. Pressure pack $2 degreaser works great cleaning those pumps and gets everything moving again.

All part of the fun I suppose but I'll make sure to run the thing on engine or 2 stroke oil before I put it away again this time and drain the tank which is also gummed up.

Why do they put such useless fuel taps and tanks on Chinese engines?
 All my china engines fuel caps leak as do the taps where fitted.  I never fill the tanks as it gets shaken up and comes out to run all over the engine.
Pain in the Butt.

Same for me, I have hunted all over the Chinese sites, and it looks like either I need to have something made from scratch or have the existing pulley modified so I can put a coupling on it. I did a quick drawing / quote on emachineshop.com and it came out to $600 for a steel adapter, seems kind of pricey to me I will have to do a real drawing and check  some local shops.

Yeah, that is stupid for a plate and a shaft. The materials wouldn't be $20 so how many hours labour do they think it will take at what price? If they took an hour to do it they would be dragging the chain.

You'll definitely do better with some small local places.

I'm looking for a direct drive plate or stubshaft as well. I have previously contacted Randy Allmand, but he was not interested in doing a run unless it was a big order (10+ units). So, where do we find a decent priced unit?

Maybe because they don't have machinists who work directly on a piece of steel.  A lot of shops nowadays expect to let computers do the work, so the setup costs are the same, regardless of one-off or many piece project.

I use a local machinist, 82 year old Korean war vet, not a computer anywhere in his shop.  He made a new axle stub shaft for my Oliver baler, otherwise I was going to have to scrounge for a similar aged used part, for more than what I paid for the new machined part.  He stays busy working 2 1/2 days a week, working on little projects.

 Good battery cables was the answer !
Installed a pair of 1ga battery cables and it fired up on the first compression stroke.

This thing is an absolute monster, very big and really kicks at start up, as it shut down, it was going to tear itself off the pallet, I had to hit the decompression as it was really hopping violently.

At a little higher rpm, probably around 1500 or so it smoothed out nicely.

 Found this on Alibaba today:
http://www.alibaba.com/product-gs/556718439/V_belt_Pulley_25cm_.html

10 inch v-belt pulley...this would certainly grab better and allow for lower rpm running...

But the description says material "asbestos & copper" thinking our customs would reject that.....

and this one:
http://www.alibaba.com/product-gs/556717222/Flat_Pulley_25cm_.html

Minimum order, 2000 units.....

Pulleys for this thing is really bothering me, if I use the stock pulley, I would have to go one to one with the gen head and even then due to the small diameter of the pulleys it would seem prone to slipping and put undue load on the bearings of both the engine and gen head. It would seem even if going 1:1 I would want larger pulleys for less slippage and reduced load on the bearings.

With the stock pulley, overdriving the gen head is out because I cannot put a significantly smaller pulley on it. This means that I am stuck at 1:1 at 1800rpm, I would prefer to bring down the rpms a little, but it seems impossible without having custom pulleys made. Seems like if I go the custom pulley route, I might as well just go direct coupling....

Good Find with the pulleys.

The company makes all sorts of engine parts so I assume they are describing head gaskets rather than the pulley material being copper and asbestos.

What you do for a couple of Pulleys is contact the manufacturer and say you are interested in importing the pulleys and want a couple of samples for product evaluation/ inspection etc.
Something like that should be able to be posted or couriered to you. Make sure you get a quote on postage first though.

A guy I know who was genuinely looking to import a container load of computer cases was talking to someone in china and they said well send you a sample of each of the 3 types we do for free if you agree to pay for freight. He said fine and thought he'd get them in a few weeks or so.
 The cases turned up the next day, air freight from China!
I think the container full he bought of the things only cost him $10 more than the freight on those 3 sample cases!

It's interesting to see those pulleys fit all the engines from my baby 165F right through  to the monsters.  If the bolt pattern is good for transmitting 30Hp, i'm never going to have any trouble shearing them on my little 3 HP.

I think if you used 2 belts that would also help with the power transmission without over stretching the belt.

Thanks for starting this thread. It motivated me to drag my little horizontal out and I had a ball with it this afternoon.  Coupled it up to a 4 Kw, 3 phase motor wired in Wye and with a Killawatt meter measured 1900 watts out of the thing.  The little China was starting to smoke a bit it the last 150W but I touched the throttle governor and she sped right up and nearly blew the lights I had attached. Working hard but still more to go.  Awesome little engine.

I found today a major source of the Noise in the thing is, like the roid, in the air intake. It has a proper housing with a paper filter but while it may provide clean air, it sure don't provide much in the way of noise suppression. I think I'll have to make up a manifold I can attach some hose to and feed it to a remote air filter box off a car.
Hopefully the plastic pipe itself won't transmit the intake noise.  I have made a manifold for the exhaust as I didn't get one with it but I'll get an adaptor to upsize it to accommodate a car muffler. That ought to sooth the angry little beast a bit.


I'd so love one of those Horizontals in a big version.  ;D

I'm still debating on what to do,  I brought home the pulley that came with it, I am thinking to draw a replacement that has a 48mm keyed shaft, then I could use a coupling or use a sheave / pulley....


I only went big because I need the HP, it is really a beast, if I didn't need the hp I would certainly opt for a smaller one.

An automobile muffler in the intake path might also go a long way to quieting the intake noise.

Re: intake noise
I used one of these     http://www.grainger.com/Grainger/wwg/search.shtml?searchQuery=soberg+fs+19p+150&op=search&Ntt=soberg+fs+19p+150&N=0&GlobalSearch=true&sst=All
It is a Solberg air compressor intake filter, FS-19P-150 and with an exhaust flange installed in place of the intake elbow, it screwed right on to my listeroid.
Most likely there is a larger size available for your bigger engine.
Made a very marked difference in intake noise. No rpm change under load with filter in place or removed........just a B I G reduction in intake noise.
I'm using a "pit-of-doom" set-up for the exhaust, so now it is just those noisy push rod/tappets/rocker arms.......................
Cheers,
Hugh

Thanks for that, just ordered one, found it on ebay for $39
