First time poster, howdy everyone!
Friend of mine asked me to look at his Stihl BG56C leaf blower. It arrived to me and he said "I can't crank it!", easy diagnosis: it was full of gas inside the cylinder. Drained the cylinder, easily got it running... or so I thought. It starts easily and maintains a low idle without any issues, but when rev'ed up, it will only hold the high RPM for 10-15 seconds then it will either maintain a low idle or quit.
So far I've put a tune up kit in it (spark plug, gaskets, fuel filter, both hoses from/to fuel tank, priming bulb (it was in the kit), air filter).
I took apart the carb and it looks in very good shape, cleaned and reinstalled it.
Removed the spark arrester to test, no difference, revs 10-15 seconds and then quits.
I also checked the bottom of the engine (below the flywheel) to see if it was leaking, didn't notice any oil from the crankshaft seal.
Any thoughts?
Thanks!
