I have a vm34 on it now, works well but I was happier with the throttle response of the butterfly carb.

Swapped out my mikuni butterfly for a round slide from a 81 trailfire. The round slide doesn't seem to perform as well as the butterfly carb. Jetting is good the plugs have good color to them the idle and throttle all work well but it lacks the snappiness of the butterfly carb. I would swap back but...

I drilled out the small hole next to the larger existing hole on the mount and it gave me enough slack to mount it there.

Definitely not a rich condition, will start with a squirt of fuel and run great till idled down or shut off and then hard to re-start. Throttle and choke cables are adjusted properly with the correct amount of free play.

I picked up a 80 spitfire, neat little sled. Problem is it dies when warmed up and is hard to start. I replaced the crank seals and swapped to a round slide mik. Has good spark cold and warm kinda stumped.
