On the A with the wico C. It jumps a nice spark but how do you get 3/16 out of a plug,it wants to jump to the side.Ive been running spark plug adapters with AC R44LTS gaped at 35 and still starts hard .Should i go hotter. On the B with the AP shaft dose not look bent rotor stops in the right spot but the points looked dirty but still weak spark,cleaned but didnt try to start.The plugs are a similiar heat rang but champion.Both tractors have had the air cleaners cleaned and are sheded.

36 A, don't worry about that 3/16" gap. On those smaller base plugs if it jumps from the center electrode to the side of the base you have plenty of spark.
~Hotter spark plugs probably won't help the starting one bit. Unless you are actually fouling your plugs a plug's heat range has no effect on starting.
~On thing that might help is to try non-resistor spark plugs, those R44LTS plugs are resistor plugs & automotive TVRS resistor plug wires or resistor spark plugs don't usually work worth a hoot with a magneto due to the mag's lower KV output & relatively slow spark rise time. MAKE SURE you are using metal core spark plug wires & non resistor spark plugs.
~Your starting problem could easily be carb related, make sue the choke is operating correctly & the gasoline is fresh.

You just solved my starting problem with my 51 B, thanks. It has always started quick but lately it will only start after I pull the throttle all the way back. Saw your "check the choke" comment. That rang a bell, just went out & took off the intake pipe, watched the choke while I pulled the choke rod. Sure enough, choke was stuck full-open, the little coil spring couldn't break it lose. I wiggled it lose, exercised it a few times, & away we go.

CONGRATULATIONS Phil, if the spark was okay, then you went to the next item being fuel. Glad to hear of your good luck and thanks for keeping us posted. John T

Phil, too bad they’re not all that simple. ~I didn't solve your starting problem, YOU did, you just used furnished information to solve your own problem...

Hi again 36 man, if you cant get the plugs to arc like you questioned, you can just use the plug wire with no plug and observe the spark quality between its end and frame. If the plugs side doesnt have a good ground to frame or if frame is closer to the electrode then the plugs ground strap, they can arc to other than the strap. Still, its not where the arc is (even with no plug) but the spark energy youre concerned with. Again and regradless using a plug or just the wire, youre looking for a blue spark and not a faint thin wimpy yellow one. A while back on here or Rummys our friend Duane Larson any myself and others discussed the advantages of having older Wico rotors remagnetized, they can become somewhat weak. On the AP, if points develop a gray oxide coat, they have some resistance and that can weaken the spark. So long as not burned or pitted, you may be able to clean/polish the point surfaces and improve their performance. Regardless, if one side sparks hotter than another, look into a possible cap or rotor or internal tower or plug or wire problem if the rotor is not wobbly (worn shaft or bushings) and the point gaps are similar. If theres no or a bad condensor the spark is weaker, but still the same elements (points and condensor and coil) fire both plugs, so differences lie elsewhwere.

Hang in there, were getting there.

John T
