Thanks! and a new question

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

   For anyone following my model B steering problem. I removed the shaft and found tons of grease with the consistency of a hard rubber eraser. I scrubbed it spotless with emery paper, added a ton of grease, and it can now be steered without superman arms.

Here's a new problem that I think may be governor related. The tractor starts very easily and runs for a few minutes and then promptly dies. It will restart immediately, only to die shortly thereafter.

I had the same problem with an earlier carburetor, and this is a professionally rebuilt Zenith. Before I dive into the governor, does anyone have a detailed drawing of what's inside or some good advice. Thanks again for all the help.

	Take the fuel line loose from the carb and see how much gas flow you have. It should have a good constant stream of gas. Is it dist or mag ignition? Could be the coil but it sounds like it's running out of gas.

	Thad - I thought the same thing. First thing I did was get rid of my inline fuel shutoff switch. Plenty of flow after that. I thought the carburetor float height adjustment might be off, but then it wouldn't start and run so well for a minute of two. It was originally magneto that I switched over to distributor.

	Could have a'foreign object' in the gas tank,blocks the fuel from exiting...engiine dies, jiggle the object,runs again...cycle repeats. You might be surprised to hear what others have found in tanks ! Super bright white LEDs make great, safe 'trouble' lights for tanks.Don't ask what happens when a tailight bulb 'trouble light' breaks when 'looking'....

	The hard-rubber situation... that's called Saponification... when greases of incompatible types are mixed, the BASEs of the grease (Sodium, molybdenum, lithium, etc) react and bind, turning them slowly into stone. You obviously caught it early enough to get it out before having to remove it with a chisel. Check to see that your oil-bath air-cleaner isn't full of something it shouldn't be, and make sure that your fuel cap is venting properly. Aside from that, the next suspect I'D have, is a failing condenser.

	You may have the coil hooked up backwards. It's opposite for pos. ground as neg ground. I think when it's neg ground the power wire should go to the + side of the coil and pos ground the power wire should go to the - side. I could have this backward but someone will hopefully correct me if I'm wrong. HTH

	Check for fuel flow by pulling the drain plug from the carburetor. Most carburetors also have a screen part of the inlet adapter that gets plugged. I saw one that wouldn't pass 60 psi air (all the pressure that was in my tank that day). That's too short a run for a coil to be a problem and reversed polarity on the coil probably isn't the problem. Too short a run and too quick a recovery. When its about to quit, pull on the choke. If it picks up for a few seconds, its fuel starvation which can be anywhere from the float needle valve to the cap on the tank. Modern caps don't have a vent but vintage tractors depend on the vent in the cap, but it should run longer than a couple minutes unless the tank is really full. A check for that is after it stops, loosen the cap, if it had a vacuum, you'll hear the air rush in. Gerald J.
