stuck intake valve on JD 420 onan p220
|johnrrrrrrrrrrrrrrrr||Took head off engine head and found that intake valve is stuck open on one piston. Engine is Onan p220. Now what do i do???
|thepumpguysc||Whats the problem?? Smack it with a hammer, knock off the carbon, get it to re-seat..
Remove the valve, see if its bent..IF NOT.. Run some scotch-brite down the guide and re-install..
|johnrrrrrrrrrrrrrrrr||thank you sounds like a plan, will smack the valve when i figure its in the right place in the four stroke cycle to smack.
|johnrrrrrrrrrrrrrrrr||Well I smacked it and still didn't get any pressure when I put a gauge on it. Took it apart and found a screw had fallen into the carburator and settled in the intake valve. My wife wondered where the screw had gone(no I not being a jerk she said it). Well ordered a new valve and will install. Have a nice manual with break-down of engine now.
|johnrrrrrrrrrrrrrrrr||Purchased the intake valves from a Cummins/onan dealer and installed. The dealer was good to work with. Was able to borrow a valve spring compressor from a local Auto Advance store for no charge. What a great policy.
|perry watkins||doubt i have such a store near me
