Folks,
I have a Stihl 362, a wonderful saw. But it seems to flood easily. If I'm turning it on and off a lot it often floods. Next time I plan to let it idle a bit before shutting it down and see if that helps. And it seems impossible to un-flood - I do the usual open throttle, no choke, pull, pull, pull - nothing. I've pulled the plug and yanked on the starter - nothing. The solution is to wait overnight. Is there something I'm missing?
Thanks!
When I was tuning one of my saws I set the carb way too rich and it was flooding on the start, so I was able to tip the saw upside down and let the gas drip out the in take (with the air filter off). If the muffler is cold you could blow air back through it so it would help to push the fuel out. I would definitely look at tuning the carb though it sounds like its too rich if its flooding that bad.
When you re-start, do you try to start on idle or hi-idle?
For sure, assume you are not trying to re-start warm on choke-set.
My 361 starts easily on idle when warm. Even after it cools a bit it starts on idle on second pull.
That didn't happen early on, before the saw had 3-5 tanks of fuel run through it. Non-ethanol fuel helps starting, IMO.
Possibly this 362, with the EPA changes added, makes it more sensitive to flooding. There again, I've had a few times I thought the saw was flooded, only to find out that it needed to be choked as it was bone dry.

Can blowing air back through the muffler possibly push a lot of rust/carbon/debris back into the combustion chamber and carb? Doesn't sound like a good idea to me, but could be just my lack of chainsaw innards knowledge.

Honestly I have never thought of that part, but the saw I did that on was just rebuilt with new exhaust so there was no rust or anything to blow back into the motor. But now that you said that you can believe I won't be doing that again definitely a :doh: moment.
You have a simple problem of carb troubles .Either the diaphragm is puckered which I wouldn't think no older than it is. The fuel shut off is set too high or the spacer gasket got installed on the wrong side of the diaphragm .Any one of them will do it .
simple rule of thumb with all of my stihls:
COLD START
FULL CHOKE, only the first start for the day, pull ONLY until you get a burp!
HALF CHOKE, pull once or twice it should start instantly, blip the throttle to drop it back to idle.
WARM START
Simply flick the pawl to run and pull, usually it will go first pull if not second will do it.
occasionally you may need to use half choke if the saw has sat for quarter of an hour or so as the fuel has had time to find its way back to the tank.
If this doesn't work I would suggest you take it back to your dealer for a tune up or more to the point learn how to tune a 2 stroke yourself.
