well i finally got my coils in at the parts place. I also got points and cond but i dont think they are right, cause the backof the box shows the h.p/year and they only show these points fit 54-63 in the 10-15hp range, will they work or is there a way i can tell, big points etc..

also rick on decarb i have some seafoam mixed in my gas, so ill post some more compression numbers after the weekend of running around with it.

does it miss throughout the rpm range or just at idle? Good to hear your making progress. Rick.

it misses mostly throughout the rpm range, but it is runnin better then it did. Took it out today and it really didnt miss at all. How do u measure the best postion for the motor (for the bracket holes)?
