Chainsaw Repair

like i said al, it's a pm380 on up tp a titan 430.
he needs a new one of these:

look at his grommet and then the one in the link. notice how the grommet is shaped? it's squished beyond use.
the oil pump is basicly sandwiched between the ports in the top of the oil tank and the bottom cover. and it needs to be a tight fit. the rubber grommet and gasket is squished flat and the fit isn't tight enough. so the pulse from the crankcase is bleading off into the oil tank, while the oil is being sucked into the crankcase.
if he'd take a small amunt of time and do this right, he'd have a good little saw to run.
