Allis B starting

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all,
Quick update, I have installed a starter motor, put a six volt solenoid on it  and a stud so I now use a push button to start instead of that horrible mechanical switch. I’ve had the magneto rebuilt. The carb was put on new by the previous owner.
I’ve only managed to start  her once since the rebuilt magneto was put on and the timing checked. 
I thought I’d take the carb off and clean it out, when I did the two inch pipe from the air filter was full of petrol. Surely that’s not right and what would be causing it ?
Any other advice on starting issues would be greatly appreciated 
Thanks

	if the FLOAT sticks in the carb, or the NEEDLE VALVE does not seat properly, then the bowl will OVERFLOW and run into the tube from the air cleaner.
	Like them all, but love the "B"s.

	As Steve noted above, the float/needle obviously is leaking. Once that is fixed, my Model C much prefers having the throttle opened only about one or two notches above minimum idle setting.

	. Verify the float is floating not filled with fuel. Also the float is set right (bend float arms). Needle and needle seat are clean and not sticking. No gummy ethanol fuel in the tank. Find nonethanol or recreation fuel to use as the last tank in the fall or all the time. Fuel additives are a waste of time and don't protect you. It's ok if running everyday with new fuel every week but any sitting it draws moisture and gets jelly like. .
