I have a '35 F12. Last fall and now today It seems to vaporlock. Radiator is full, but block still seems to be kind of warm. Fuel lines are according to original and from pictures as best as I can tell. It just died off...then trying to restart I have to put the choke on full then after a few cranks it stutters a little then just dies off. Trying to open the choke once it stutters doesn't help. It also seems to crank a little harder like it was over heating. Block and radiator were completely cleaned and dismantled during restoration. I was disking toady in second gear temp is mid 80's. Same as last fall, but that time it was at a show and I was pulling a single bottom plow, very embarrassing took well over and hour to get it to restart and then ran fin as long as I wasn't working it, and just running around the show grounds.HELP!!

I had similar problems with my F14. On mine the gas line had corroded enough that hardly any gas got through it. Had to put a new line on it.

Try something simple before you tear into it. Undo the gas cap and see if you are pulling a vacuum as the gas gets used up. I was, until I drilled a small hole in the cap to relieve the vacuum. Did the same thing you describe.
