1998 sabre garden tractor with 20 hp vanguard v-twin started

Customer Question

1998 sabre garden tractor with 20 hp vanguard v-twin started spitting fuel out the overflow tube at carb. I put new battery in to see if it was a low voltage to float solenoid prob and it worked for several cuttings but the next time I went to use it it started spitting gas again. I can heat the the float solinoid click when I turn the key. what can I do to troubleshoot this intermitten problem?

Fuel out the overflow is the needle valve and float m nt shutting off the gas entering the carburetor. Need to check the float and the needle valve. Do you have the engine model numbers? example(###) ###-####B1

See link, is this your carb? The fuel solenoid had nothing to do with the fuel leaking from the overflow.

that is it. could it be the solinoid is weak or the needle valve worn out?
Expert:  Curtis B. replied 1 year ago.

Solenoid is NOT problem. Needle valve may need to be replaced, or the float may not be floating! Float has to push needle to seat it.

Solenoid is anti-backfire solenoid and closes the main jet when the key is off, keeps engine from backfiring when key is turned off and engine is hot. Serves no other purpose.

10-4 on that. I will check it as per link you gave me. I also have a factory manual. I also would like to say that when it's not spitting ( started late in season last year ) gas it still runs excellent. thank you....
