76 Sno Twister jetting.

We have a 76 340 l/c and am wondering what the stock carb size is, and what the stock jets are in these carbs. The sled symptoms are that it bogs at low idle and you need to play with the throttle to bring the rpms up and then it clears up and has instant throttle response.

Thanks,

Mikuni VM 36-23
jet needle fourth slot from top of needle
fixed high speed jet 320, 220 came with them as a spare for higher temp or elevation

I have some charts that could be scanned and emailed for high speed mixture adjustments

These are specs for the 75 S/T 340 free-air, not the 76 liquid. I think he found the specs he was looking for on another site.

VM - 36-41
M/J - 340
J/N - 6DH4
N/J - 159/Q-5
T/V - 3.5
P/J - 35
