Re: engine won't idle-how to remove flywheel
If you took the flywheel nut off and have a puller, it sounds like you are on your way. Tighten down the puller and rap the center post/bolt once or twice with a hammer (firm but careful).<br /><br />You can get hurt taking off a flywheel, so wear gloves and be careful. When it pops it makes a sound that may make you believe it busted in half, if you don't know what to expect. Don't get hit by the puller when the tension is released.<br /><br />I'm not sure what you mean by cavitation -- might be exhaust coming out down by the prop if you are running in a test barrel. Make sure you have enough water in the barrel (water level well up on the leg). It's also not a good idea to run at high rpms in a barrel, at least for sustained periods. The motor could overheat.<br /><br />The proper oil mix might be a little richer than 50:1 (i.e., 48:1) -- might err on the side of a little extra oil.<br /><br />I'll be curious about your findings, by the way, as I have a similar problem with a 9.9 Chrysler (95HA). I rebuilt the fuel pump (and cleaned the carb), but still have the problem -- might go through the fuel pump if you haven't done so. In my case, I suspect I've got a weak coil. I just got it back together, so I think I'll let it be for a while -- but would like to hear what you find with yours.
