Tractor missing

Bhunt · Jul 11, 2013

I have a 1952 case SC with a Fairbanks Morse Magneto been having a problem with the tractor missing under load the more gas I give it the worse it gets seems to miss sometimes when the angle of the tractor changes like on hills. But mostly under load or just holding the brake. I can usually stop the miss by decreasing the gas. Id appreciate any help plugs are ok. spark is a little weak but has always been like that. I can only say it has compression but don't know how much..

Did you try opening the load needle on the carb.? Give it a half a turn open and see if it helps. Turning the load needle counterclockwise gives more gasoline.

well if Its a SC,, Your Better off That its GONE ,,. LOL.. seriously.. the uphill downhill slope reminds me of the crazy shi!!I went thru with 2 of the sc;s I had here , it was a craked burned out intake /exhaust manifold ,,they are reapiable , mite spray ether around the manifold at idle and see if it piks it upp , when the 3 rd one came here I knew , what its problem was .., this one wouldn't run at all ...It is a Very Common problem for the timid sc that I still dispise to this day ... if you have eliminated everything one at a time with no improvement .. pull the valve cover and make sure the rocker arms are ok , mite be a good time to afjust valves ..

Can you try changing the timing a little by rotating the magneto and see if that helps? Sanding the magneto points with some very fine sand paper may help the spark.

It stopped raining got a chance to spray around the manifold nothing? checked the timing looks ok goanna look at the valves today.
