Hi everyone - I need some help with a YS 91 AC engine.
I have two of these engines however one of them I can't seem to get running correctly.
I have replaced all the gaskets, checked the glow plugs, checked the fuel tank, checked the one way valve, adjusted the tappet settings and TRIED to follow the directions as far as setting the low/high end.
The problem I have is that I can get the engine to run on high end without a problem, the idle seems to be a little difficult but when I think I have it, I cannot transition to high again, the engine sounds like it is starving of fuel when I go to high.
Any ideas on where to start or what to do?
Then engine is practically new, I have run it about 20 times but always had a problem so I don't want to use it anymore - I think I would just like to get rid of it if I can't get this thing running.
Any help would be greatly appreciated.
Thanks
