General Discussion Area / Lawn Mower Engine - Air intake gasket.
« on: 14 April 2014, 08:53:11 »
I've got an old lawn mower thanks to FatherT
It's engine is a Briggs & Stratton Quantum XM 35, was a pig to start this year. So took off the float, cleaned it all up, fairly clean anyway, blast of carb cleaner in all its bits, new air filter and put it back together. Problem was the gasket on the air-intake was in a right state, so took it off for now. Re-assembled, without gasket.
Pull cord 3 times to prime, pull again and bang, straight into life.
Runs well, apart from after a while, the revs get very lumpy, it gets so bad it stops every so often. I'm thinking as it heats up, it's letting air in at the intake, more than it should, lack of gasket giving it lumpy hot revs?
Thinking of this:

But can I use a liquid sealer? Or is better off going for one of these kits?
