Pony carb float level ? giving me grief

870 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.

I have changed the float level several times and still have a gas leak thru the carb. I suppose that I will just have to shut off the gas at the sediment bowl every time I turn the engine off. That might be a little annoying once I put side panels on.
Are carb rebuild kits available for your application? It sure would be nice if you could just replace the needle and seat to fix the problem. The shut off valve is great for longer durations of down time but if you plan to run the tractor often it would be nice to get on and go without fussing with side panels and opening the fuel supply.

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..??
