Let me ask you this then did you also do a modified carb say from I think it's poleman ?I'd do the swap again for sure. I couldn't advance the limited coil at all or it would pop pretty bad. Stock coil never really had the throttle response that I love. Granted my swap was on the 65cc model but I usually tune it to 15,200 give or take. Much easier to tune if ya ask me.
Ty mikeNope. He has a 385 carb
Mo is betta!What's wrong with the stock 665-681 carb??
