What Carb is on the Ambassador

another carb question for same bike

What would be the best jet or jets to use, say at 450ft sealevel also would a 26 mm be better if I could find one hint hint? Dane
 
A #84 high speed jet with the needle set in the second groove. The air bleeder should be at 1 to 1.5 turns out from fully closed. These recommendations are for the 22mm carb.

Hi Dane, To use a 26 MM on the Ambassador would require more changes than you would want to make. I purchased all the 26 MM carburetors from Whizzer several years ago, and sold all of them but the last 3. The last 3 are for my personal use only and not for sale. In order for the 26 MM to work correctly on the motor you would need to increase the intake port I.D. to at least 55/64", and would also require the intake manifold to match.
Have fun,
