SOURCE: old homelite chainsaw, wont pull fuel

most of the time there is a air leak in one of the two crank shaft seals.to get to them you need to pull off the flywheel and the clutch assy.look for wet areas. that will be where the seal is letting out the oil and air.If you keep putting starting fluid in the carburator you will burn the rings,the piston and the cylinder up

There is a recall on the UT models, all you have to do is call the costumer service center for homelite. they will give you a number for the closest warrenty center that will adjust you throttle cable free of charge. I went through two UT 10520's before i started researching the problem.

1 1/2 turns open. Start unit then fine tune from there.
