Hey all I am new here but i have found a lot of help here in the past and thank you for that!

I have a Massey Ferguson 35 Turf Special with the Continental 4 cyl
I just got it going again after sitting awhile. Ran great (first 3 days) and now when i throttle it up its skipping and sputering... pull the choke out and it helps a little but still sputtering. I have had problems in the past with the coils going bad constantly and i am thinking this may be my issue rather than a fuel issue. Also it is 12volt positive ground from the factory. I didnt realize this a couple years ago and hooked it up like a car... it ran extremely hot and an old timer friend of mine knew exactly my problem.... so i changed that.

where does the + wire on the coil go with a positive ground?
