Rough Engine, please help

Ok Roger, Thanks. I'll see if we can get together soon to check that
out. How do you check the cam-- pull the rocker arms, pushrods, and
lifters, and peek into the hole where the lifters were?

Thanks,

I repeat. Make that next flight after the entire valve train has been
checked. Just the broken spring could have caused other damage that will
come back to bite you. I've been talking to another guy who had the lifters
in his 210 go bad just under 700 hours even without any broken valve
springs.

The cam shaft is driven directly by the engine and, when things go wrong in
the rather delicate valve train, all that power can really screw things up.

Thanks for the replies. It WAS the fuel injector, which was blocked.

Good deal, John.

Any idea what caused the clogged injector? Bad gas?

Good question!

My mechanic posited that the broken valve spring somehow facilitated
the clogging of the injector. I'm not sure I can see that...

Also, it's kinda hard to resolve the "intermittent" nature of the
problem from flight to flight beginning a month or so ago, i.e. "When
did the valve spring break?", and "When did the injector clog-- and
was it suddenly, or gradually?".

I will be pondering these things during my next few flights!
