my 95 322L is dying down a little more than i think it should when you operate it. I'm thinking about turning the fuel up a little but was wondering if else has had a problem and maybe it's a screen somewhere about stopped up instead......
There can be alot of reason for this and not always on the engine side, but if it has alot of hour then i would guess the injectors and rack are worn. Some basic troubleshooting should be done, boost, fuel pressure, blow by etc. When i set them up I advance the timing .5mm, adjust the fuel setting to the high side of spec and can turn up the torque screw on the governor if needed. By just turning up the fuel you are just masking the real problem.
it's an older machine with a lot of hours on it, I did find in the parts book that there is a strainer in the governor and one that looks like it's under the toolbox, i will check those before i start doing anything major to it...i guess
A basic service is always a good idea if one hasn't been done recently. Does it miss, knock, smoke, use excessive oil?
it's really just a good old normal motor, might even be that I'm expecting more from it than it's supposed to do..... here's a video of it doing some light work http://www.youtube.com/watch?v=IHk8qyNK3Vc
Sure sounds like it needs a tune-up. Does it smoke black when your'e working it and it drops in rpm's? Blow all fuel lines, change the filter and clean the screen. Then you could fit a clear hose on the return and check for air in the fuel. Next is to check fuel pressure.
