might be clogged injectors .. or the injector pump isnt actually working ..
crack open the injector outlet and see if fuel is there .. in pulses ...

first is to check the fuel rack that runs through the fuel pump .. if it moves freely, thats good. ..

check the filters if it has any and clean if necessary .. or replace.

check decompression lever .. does it open exhaust valve so that you can turn motor through all 4 strokes fairly easily ...

crack open the fuel pump to fuel injectors line and spin the motor ... getting fuel leaking out --- i would hope so, but if not .. find out why.

i think there is more ..  but ill stop here .. there is a check list here somewhere on the forum i think

is it a constant speed setup ( with generator that is now removed ) or variable speed(rpm)?

If the rack can move fairly freely -- with the run/speed control set to off .... its probably ok to try to start ...
i would remove the air filter if it had one and prepped to choke off the air intake with a block of wood or similar to shut down the motor it is wanted to run away --- high rpm.
a fuel shut off is not fast enough to starve it if it is running away ...

i dont know of any videos to properly take them out ...


all i know is that you dont want to bend the rack any ...
the cotter pins that are bent around to hold the interlink pins will most likely break so you should source them -- i used pins out of a mix set from Orilleys ....

i dont have a way to test the pump at my place ... iv seen a home made stup on you tube , the guy used a press and some fittings and a pressure gauge to check the injector trigger pressure .. but i bet the same setup can be used to check for leakage -- doing a leak down test .. just pressuize and wait a bit fto see if the pressure drops durring a set time -- and i have no idea what time duration that would be but i would guess two minuets ....

if its one of the pumps .. you might need to replace it .. or get a replacement piston .. i dont remember seeing any seals when i took mine apart to clean the shalacked ( is that a word ? ) diesel that was gummed up in mine ( rust too ) ...

I would hope that the piston is softer than the body of teh pump ... i dont know.

hi ..
you could try getting all the copper seals replaced .. or pull them all and soften them yourself ... polish flat on glass,
there might be a crack in one of them from being over tightened ...
or a crack in one of the fuel lines ...

you can also get a fuel pump and pressurize teh fuel and let it run for a while ( i mean teh electric fuel pump -- not the motor )... it should flow through teh return

as an idea i just had .. when electric pump is running ... tie strips of paper towel in various places, looking for a slow collection of diesel if you cant see the leak

find the rack ...
its part of the fuel pump for the injectors ...
make sure it moves mostly freely .. it needs to control teh fuel burnt or you might get a run away condition and get a destroyed motor or worse ...
check my pictures in my threads .. and my you tube videos ...
youll see im sure.

it hurts nothing to check the fuel filter and oil filter if it has them ...

does the decompression lever work on teh exhaust valve?

As far as I can tell ... the air duct is one piece that's held in 3 places on the motor ...

First picture is location of bottom attachment point that I have yet to get loose

The second is well .... the rest. It looks to me that 2 in of material is rusted to gone for most of the length ... the shape tapering to the 2 bolts at the bottom of second picture.

This belt is about 1" short or so ...
I got it on but it was kinda tough ...
I'll post a picture when I can ... don't know why I'm failing checks again

I had let them cure for 2 days ... well 2-1/2 days and the wax paper peeled off nicely

I take it you don't have a generator head attached to the SR1 ?
