I thought about that, too. This one's bent in two directions at two places, and I think I could straighten it, but I'm gonna look at the other one from the same cylinder and see what's up.

I traced my back-firing out the carb issue to a bent pushrod, intake on the front cylinder. I'm gonna pull the head to start looking at why it bent, but I know I'll need a couple pushrods and probably a head gasket. What's the going price for these? Model 40C, Ser. No 70263. I'm in California, zip i...

My first inclination is to stay with the original stuff. I've got a couple old Motor's repair manuals from the 40's and 50's that I've been looking through to find trouble shooting steps to isolate the problem. Compounding things is that the motor doesn't want to start, just spits back up the air fi...

Where did you find the alternator and conversion parts? The best price I can find for the lowest-amp one-wire is about $150, then I'd have to pick-up the conversion parts. I'd thought about something like that, but I might end up putting the crawler up for sale, so I was thinking I'd try to keep it ...

There's a guy on e-bay with a store advertising a 4-wire, 6-volt, positive ground regulator for 30 bucks, with shipping to my area for $13 more. Does anybody out there know what the Delco part number for the stock regfulator is?

Had it apart, cleaned (filed) the points, checked continuity through the coils (all seems OK). Found a new one for $55 bucks and ordered it, they say it will be here in a couple of days. Thought about the one-wire alternator switch, but then I'm out the cost of a coil (12-volt), new battery, alterna...

Looking at Voltage regulators for my 40C. Local Napa store says all he can get are 3-wire regulators, mine is a 4-wire. Other store in town says he can order a 4-wire, for $96 bucks. The parts for sale here says they cost about $40 bucks. Has this just not been updated, or is the guy here way out of...

Thanks for all the ideas! I'll check for a stuck valve, came across an older posting where somebody said they found a valve had got stacked up with carbon and wouldn't close all the way. The floats appeared to be loose, but there was some gas dripping out when I ran it last, so maybe they were stuck...

I ran the crawler out of gas, and it now wants to run on one cylinder and back-fire out the other. I pulled the carb to make sure nothing was clogged and found a plastic tapered sleeve in the throat. Carb tag says "Marvel-Schebler TSX-530," with the number"70" stamped beneath the "TSX." The plastic ...

He had by-passed the ignition switch, and there were no lights or other accessories on it. I had downloaded a wiring diagram, re-wired the whole tractor to make sure there weren't any shorts to ground, and dis-assembled the original ignition switch, cleaned all the contacts, and re-assembled it, wor...

Bought a 40C, not running. Turns out the guy had a 12 volt battery in it and had cooked the oil out of the coil. New coil, 6-volt battery, starts right up and runs like a champ but showing no charge. Would that have fried the generator? regulator? or both? Have a Motor's Manual for old cars that has...
