Starter on 94 sidekick strange cranking sound

[zukitrek]

That is my suspicion that whatever I did to commutator, helped for now. Yes. Just like magic engine smoothed out just like that when I plugged hose. Never suspected the mini misfire would be that. That had me playing with idle settings like crazy!! Booster was repaired 7 years ago (not by me) so if I don't find a repair kit then is a new one. I discovered the problem while car was idling: I applied the brakes, idle went up and smoothed out. I said OMG, this is it!! Also my t-stat was also contributing to temp being above middle mark. It took like forever to open and not quite well, even though I tested it on a pot (lol the same I used for the Kick thermoprobe!!) It opened at 215f or so. So Im thermostat-less for now, but car is just fine and dandy, idling perfect with timing spot on and temp no even close to middle. Will let you know of any new findings.

Thanks!!!
