I left the gas valve open the last time I ran my 1940 M a couple weeks ago, No gas was dripping out of the carb when I found it. It wanted to start right up but sputtered as if I did not have the choke correctly positioned --then quit. Would not pop again unless I sprayed ether into carb, but then just pop a couple times.
Gas goes through the line at least as far as the carb. Can't get the carb off because of one bolt on the backside. Any way to clean out the carb without removing it?
thanks in advance.

Thanks guys. The tank is full of gas and it poured out when I disconnected the line from the carb. I'm used to feathering out the choke -- I thought I had it down to an art on this tractor. I'm pretty sure that the needle or something is gunked up from the gas dripping through and then evaporating -- well, not that sure.

I'll work on getting a wrench -- everything else loosened in 5 seconds, fooling with that back bolt wasted an hour.

I use a box end 9/16" wrench for the nut on the engine side of the carb. I had to use a grinder to thin down the side wall of the wrench to get it to fit though. Works good for me and I am also happy when I can find that one special wrench for that application.

E,
Most of us have made (or purchased a special bent wrench to access that bolt. If there was no fuel running out, the needle valve held correctly and it did not flood. As Allan pointed out, it may be just a matter of correct choke application. Another possible issue is that there may be no fuel in the tank (I am not being rude, it happens to many, including me) If it was left open, it could drain it dry. The worst is having a tight intake system and filling the engine topend (and sometimes, crankcase) full of gasoline. It seems impossible, but gravity is weal but insistant. Good luck. JimN

Sounds perfectly normal to me. That's the way they are when started cold.

When they start to "sputter", you have to feather the choke a little until it straightens out.

Or maybe you mean it did like mine did. I put a full tank in Puffy, my 1940 M, and then went on a trip, and when I came back I had an 1/8 inch of gas all over the floor of the shop. Man can you imagine if I'd left the compressor turned on and it had kicked on or something? That was about a year ago and I learned a valuable lesson. The tractors stay outside, and the fuel gets shut off at the tank. Once I got used to doing it, it just comes naturally now and don't take a bit longer than starting up the old girl. Harley
