The thimb throtttle does have 3/4" of free play (how to adjust?) but I think this is a classic carb problem.

With the yardwork, Thanksgiving, etc I could really save some time if anyone knew the quick answer. Sure, i could give up and put the Mikuni on but I dont have time right now and thats a chickens way out...this must be fixable.

I would really appreciate any insight on this (float-slide-etc).

Thanks a bunch!

Hey Pete,

Our Beast has considerable throttle free-play as well (which is a good thing), but what's paramount is that the throttle opens and closes fully. If you need to adjust it, there should be a mid-cable adjuster downstream of the thumb throttle.

Regarding the bog, check the air / fuel screw. I can't remember where ours ended up, but gently turn the screw until it seats (counting the turns) and then back it out a different amount. That type of flow-chart approach will find the answer quickly. Theoretically, the ideal air / fuel ratio will produce peak idle rpm; so much so that you might need to turn down the idle and start over. The really hard part is finding a screwdriver to access that bloody screw under the carb. I think I ended up using a 1/4" ratchet and a #2 phillips bit, but I can't remember for sure.
