WT 771 bore photo.

Here is the WT-771. No choke.- The hole you see @ the edge of the carbs velocity stack is the main outlet. no fancy check valve here- k.i.s.s. I had mentioned a few days ago bout the butterfly mods- The one on the right was just a hair too large. With the butterfly closed it idled a wee bit too high, It would be perfect with a high rpm clutch spring. This butterfly mod increases the the air flow so much-- across the 3 holes in the bore, you can set the lsn @ the perfect mix- with zero bog. roughly 3/4 turn! This was on the 990 i should say. This is a Palmgren branded x-y axis. Clean up the errors on the ways- remove the backlash- How did i ever get anything done before this xy and a radial press.
