Just got a 1984 Honda 200 three wheeler Big Red. 2 questions actually! Generally it backfired on deceleration than will dies and the plug is fouled. After I change it or clean it, it will run fine, sometimes for about 30 minuted sometimes a few rides. What do I need to do to fix this? Where do I start? 2nd. My battery wont stay charged for long. My pull cord broke the other day and right now I am counting on my electric start. I'll put a charger on my battery, get it charged and I only get a couple of starts out of it. Then its dead. Will not stay charged over night for sure. Usually if I ride it I won't cut it off because I'm not sure if it will start. Shouldn't it be staying charged and be able to us the electric start? I thought pull start was the backup. Is this normal if not whats up? What do I do? The battery is new, for ATV and fits in the spot but not 100% sure its the right one, what amps should it be?
