Pony carb float level ? giving me grief

907 Views 3 Replies 3 Participants Last post by  DJ54
I've cleaned out the gas tank on my "new" Pony, replaced the sediment bowl and line to the carb with new stuff and the Marvel Schebler carb leaks gas through unless I turn the gas off at the sediment valve when the tractor is not running. I have had the carb apart and all looks well inside. The needle & seat seem fine. I am going to experiment with minor adjustment in the float level and not opening the valve on the sediment bowl fully, to see if that will solve the problem. Any suggestions? Thanks.

Are you adjusting the float on, or off the tractor..?? If on, hold up then open sediment bowl valve, and see if it shuts off fuel flow. If it does, then the float needs to set deeper in the bowl.

I've had the float, or pin slide sideways a bit, when reassembling, and bind, not letting it rise in the bowl, also.

Did you check to see if maybe there is a pin hole at the seam in the float letting gas in, and not letting it rise in the bowl..??
