My tractor works fine .. but ...

1952 8N, side mount, 12V conversion ? My tractor runs fine, almost all the time. I can?t track down what is causing an annoying problem. Here is what happens, using a 5 ft rotary mower (w/ORC!) I find that when I make a hard 180 degree right turn at the end of my row the motor cuts out, as if I turned off the key, ?.but just momentarily. It usually self corrects and I start another pass. At the other end of the pasture I pull a hard 180 to the left with no problem. Go down to the other end and go right and it?ll stutter again. I looked for a wire that could be grounding out, so far I have not found it. Also, the other day it was cold, so I started it up to warm up and walked back to the barn for something. A minute or two later I heard the tractor begin to die, as if the key was turned off. I quickly turned around to see it catch and speed back up again ? no explanation. Ideas?
 
I have two 1951's that have exhibited the same symptoms when turning. If ignored they will eventually just plain quit and stop dead. Surprising result is that they simply run fine again after I re-gap the points. Really doesn't matter what points you buy, seems all the current wear blocks do just that, wear. Worth a look see.
 
My 601 does that if I am sidehill or uphill on a right turn with a mower or other load. I have figured it was something unporting in the carb, but don't know. I hope you get an answer!

I'm with Bruce - Check for side play on float. Too much and it will hang when tractor leans to one side. To rule out float level problems; remove drain plug from bottom of carb and install a barbed hose fitting (should be 1/8" NPT). Slip a 6" length of clear tubing onto the fitting. Insert a stiff piece of wire into the hose to hold it upright or tie hose off to hold it up. Open end of hose must be above float bowl to prevent gas from leaking out. This simple device will allow you to see the amount of fuel in the bowl. Take it out and make hard right turns - If float level drops then Bob's your uncle.

Bill ? I like your idea, like an old school manometer, and I think I have the fitting! But?I need some convincing that a stuck float can cause trouble in a manner of a couple seconds. Heck, I can turn the gas off and still make it once around the barn? So what you and Bruce are saying is that, before the event I must be drawing fuel such that if the level in the bowl drops a fraction of an inch, the motor will starve in the blink of an eye if the float doesn?t allow more gas in?
 
IIRC manometers measure vacuum or pressure. The hose just shows fuel level and I suspect your float level is a tad low.

You may be correct, I was trying to give you an inexpensive troubleshooting step. Most fault isolation is simply a process of elimination.
