Polaris trailboss 350l carb issue?
I've been working on this new project of mine for a few months now. I got it for $60 and was a pile of junk i got up and going. After riding for a few days it back fired and quit.
I took the head off to find the piston missing a chunk and half the skirt off. None of the remains to be found (looked likes been that way for a while).
New top end/bore and still no luck - more than 70 psi though (haven't test but feels alot more)
doesn't run yet for odd reasons. i've got both screws on the carb 2 turns out. With a little burst of arb cleaner it sputters, but thats it.
I've got spark, 32:1 oil mix, compression, choke on, new carb kit.
any ideas why it doesnt run or sputter alone? Plug has gas on it when i remove it.

i would definatly pull the motor to get the pieces of the skirt. theres no way the piece can make it into the top of the cylinder to get out.
i would likely guess taht the piece has messed with your bearings if its been in there a while causing bad bearings and the seals are probably gone too.

Ran once it shall run again.
Havent split the case yet, but when i got it(piston was destroyed before i got it). When i pulled the jug off, me my brother and my friend could not find any pieces of the piston. you can see some where in the case from them.
Now, when I first got it running(drove at the time) it only had 70psi and it ran for a couple hours. made a nice loud pop and stopped. Thats when i pulled the head off to find a destroyed piston.
currently when i spray some carb cleaner into the carb, it does sputter.
The reeds appear fine.. anyway to easily check the bearings/seals though?
