So I picked up a cherry Jonsered 2165 off marketplace and the guy said he had started it up 2 months before I bought it. When I get it, it will not even think about starting. Best I could get is 3 gurgles after dumping fuel into the intake and holding the trigger down while pulling. Compression is 130, no visible scoring on the piston from the intake or exhaust side. I haven’t pulled the jug. I bought new OE parts for the usual suspects and for the more expensive parts I swapped from another running 2165 I have on hand. Here is what I have done so far:
New plug (ngk)
New fuel pickup and impulse line (oe)
New fuel filter (oe)
New carb kit (oe)
Disconnected stop switch
Verified spark outside of cyl
Swapped coil
Swapped flywheel, checked key
Swapped gas tank
Swapped carb
Swapped recoil assembly
All this with NO IMPROVEMENT. Starting to pull my hair out on this one. I just got new base gaskets in so I can pull the jug next but given compression seems acceptable and no scoring I am hesitant to do so. If it was an air leak, you would think it would at least run for a little bit. Only other thing I can think of is the intake boot, but visual inspection didn’t reveal anything. Running 40:1 red armor on 93 non ethanol.
I’m a parts-swapper, I never said I was a mechanic!
