Yammer 2210D

Anyone know how much compression a 2210d should have?

Not exactly, but probably above 500psi.What Should My Compression In PSI Be?

Testing compression on these is so difficult that I would find some other way to determine whatever it is you want to measure.

What do you observe, that raises this question?

Can you say a little more, California? I have been experiencing (what I think is) above-average blow-by from the crankcase vent on my 155D and was planning to check compression soon. But maybe not the best course of action?

Hopefully not hijacking the thread OP

I bought new injectors, and had such a difficult time getting original injectors out that I felt they weren't worth saving for re-use.

See my old longwinded post where I essentially cussed each step of the job. I expect your experience would be identical.

If it really needs valve guide seals or new rings, then I would just start on that. But if it were mine I would just live with it until the blowby was unbearable, or it became hard to start. It might take years to get any worse, I could live with that.

Thanks guys. CA great documentation in that post! Excellent way to scare a neophyte shade-tree wrencher like me away from even trying ;-) Winston, I saw that video last week after I started my research in the wonderful TBN archive. I would say that, after 1.5 hours hard mowing last week it was indeed at that level. But it starts easily -- once I put cetane in it's been amazing -- and it doesn't smoke start to finish that I can tell.

I'm wondering -- now that I've thoroughly hijacked the thread -- is there a relationship between overheating and blowby? Could it be blowing more because the engine is too hot? A post from a few years ago the guy was thinking he needed to muriatic acid flush his rad core and that would help. I still haven't fixed my engine temp light. Stupid, I know.

I suppose there could be a small relationship between overheating and blowby but very small. I was probably the one you read about with the muriatic acid flush. I did do that successfully. Same radiator was on the tractor when I sold it several years later. If you have reason to think you are running hot you need to get that fixed. Overheating is a head gasket killer on these little engines.

The blow by on my YM2000 is probably that bad if not a little worse.

Still has plenty of power and it's easy to start.

I keep the oil topped off and run the mess out of it.

Lots of White Smoke. New Injectors did the trick. Thanks
