I had to get a new Fuel Bowl Assembly as the plastic shut off on my old one snapped in two. Ordered one from Sparex (Canada) and installed it today.

I dont believe the new shutoff is working properly. I had the tractor running and closed the fuel shutoff and the tractor continued to run at idle for about 10 minutes before it began to sputter. Im thinking it should shut down much faster than that. Anyone with any experience on how long it should run?

I have a bucket under the carb to catch any fuel that may leak out overnight, but hopefully it will be dry tomorrow morning.

Thanks
 
Did it just sputter or sputter and die?
If it just sputtered then you have a problem. if it died, what problem?
Need it to die faster? Rev it up.

Realize when you shut off the bowl, there is fuel down the whole pipe from the bowl to the carb. Inside the carb is a quantity of fuel keeping the floats up. When you shut off the bowl the tractor burns what is in the carb under the floats, the floats drop and let any fuel in the line enter the carb until there is no more available. The engine keeps running as long as fuel is still in the carb and fill pipe.


Some advice, avoid using any ethanol-additive fuel near the end of a season. If you store the tractor with ethanol fuel it will absorb water, rust the tank/etc and turn to 'jelly' after six to eight months and you'll have a hard time or impossible time starting and running the tractor. There is a small engine youtube channel that showed none of the fuel additives fixed the problem.

10 minutes at idle seems like a long time. Why don't you just disconnect the fuel line at the carburetor and see if it's leaking.
 
Shut ENGINE OFF.........

Close fuel supply at TANK..

OPEN drain Cock on Carb.......Did FUEL stop running......?

Do the same....disconnect fuel line at Carb.......

Fuel all drained out into the bucket I put under the carb. Will be removing the Fuel Bowl Assembly and returning to Sparex for a replacement. Hopefully the second time is better.

Thanks everyone.
