I am intalling a Mikuni 34mm TMX carb off of a polaris 440 race sled. Everything was going so smooth and was coming together great. So i get everything hooked up and i realize the piston valve only comes up about 3/4 the way so there is still about a 1/4 inch sticking into the passage. I'm thinking there is some stopper in the cable and i'm not sure if i can fix this in any way because i would realy like to get this carb working before winter. Any help would be apreciated.

 

If taking the slack out doesnt work. maybe the throttle lever off of a machine using the 34mm, has a longer pull and will help. Or a twist grip?

 

Ya thats the problem. It's like the cable will get to a certain point and won't go any further. But when i would loosen that cable screw where it screws into the top cap of the piston valve it helped but the valve still stuck out into the passage a little. I just don't get why the cable stops it like that.
