I work too hard for my money, but if I was to make a wager we would be standing side by side...My $ is on the flywheel side.
Also my experience on other saws, but on 1121 series Stihls, it is almost always the flywheel side. Good practice to change both in any case.The clutch-side seal you can easily check by having the saw idle with the chain/bar and sprocket cover removed and spraying some WD 40 or other oil around the clutch drum. If the engine speed drops (or changes) you've got a leak there. Same goes for the impulse hose (which can be removed easily after removing the rear AV mount bolts pull off the crank case connector and then pull out through the carb box).
PS: In my experience the clutch-side seal usually starts to leak first...
That to me does not sound like a cut and dried case of a bad seal. When the flywheel side seal went out on my 260, the idle was high and could not be adjusted down. I suspect that you may simply have fuel pooling, and no real issue at all. Of course, a vac/pressure test would answer that.
Do a muffler mod and that will wake the saw up. Pull the cover and make holes above and below the existing hole. Then check the carb adjustment.Thanks Brad, also excellent videos! I've seen a few of yours just in searching. Great work!
Fuel pooling, what does that mean? Sorry if that's a newb question.
Gday Brad
Mate for those that don't have the proper tool can you show us or suggest another way to remove the seal ? thankyou
