I have a 2003 that I acquired and I put a new carb on it. It starts good and idles good but when I try and drive it I have no power and it starts backfiring both ways. any help would be pleasing and thank you

My 2004 is backfiring on deceleration. Check the rubber boot between the carb and engine..they will cracking. .replaced mine already..other than that could be plugs..wires..exhaust donut
Good luck.

I had a bad ground on my coil. Did the same thing. Hooked a jumper wire to various grounds to check if the problem changed. Didnt look corroded either.
