Hi, iam 16 yrs old an iam a aspring small engine builder and iam working on a 18 HP Biriggs V-Twin Vanguard for the family lawnmower. The problem is that when u start it up and mow for about 30 min. and if u stop it, it will never start up. So i went to the local B&S dealer i got a new magneto and a carb overhaul kit. Since i put the new magneto on it it will not turn over now? I charged the battery and did wat i thought was good. I dont know if taking the engine out of the frame was needed? So i herd of a (coil air gap) thing, and i dont know wat that is, so any suggestions is greatly appreciated.
Thanks alot
