PLEASE HELP!! 23hp Vanguard carb fuel shut off solenoid sticking
Sometimes the carb soleniod sticks shut and the motor won't run. Lately the wire to the solenoid has beem disconnected and the motor still runs.
I took the cart for a test run and didn't have much power. The motor stopped and I had to tow it home. Can I remove the needle valve in the solenoid? I have fuel supplied to the carb. and have spark to the spark plugs Thanks,Ted |

Re: 23hp Vanguard carb fuel shut off solenoid sticking and now low compression
Update!! The motor backfired just before it quit. No compression in front cyl. Good compression in other cyl. Rockerarms are moving and piston is moving in the no compression cyl. Please help. Thanks,Ted

Re: 23hp Vanguard carb fuel shut off solenoid sticking

Re: 23hp Vanguard carb fuel shut off solenoid sticking
Tod, Just checked,both rockers,pushrods,valve springs are moving.
I am also looking for a V Twin engine repair manual. Online or book form. Thanks,Ted |

Re: 23hp Vanguard carb fuel shut off solenoid sticking
are the valves stuck open? check to see if you have .004 play on both intake and exhaust
how much compression do you have? measure with a compression gauge. You might have blown a head gasket |

Re: 23hp Vanguard carb fuel shut off solenoid sticking
Shawn.m, I had no compression on the compression guage and the valve clearance is set to the specs. I will look at it closer today. Thanks,Ted

Re: 23hp Vanguard carb fuel shut off solenoid sticking
if the valve clearence is set to spec and the valves are moving up and down. It is looking like a blown head gasket, chipped valve or something else hard like a broken piston
