Need some help with sizing the jets for my 32mm, carbs. Engine is a 1/2 VW, std. crank, 92mm cylinders, set up for 2 carbs. Intent is to derive about 32hp @ 3500RPM.
My two carbs come from different sources, and the jets under the plug below the bowl have different numbers on them, 250 and 280. The mikuni website lists jets up to 500, with lots of discussion, more tuned to motorcycles then 1/2 VW's.
Need some help from anybody who has gone through the process of elimination in selecting a jet which will give the proper mixture for both takeoff power, and reasonable cruise speed, with EGT 1200-1300.
it has come to my attention that many are useing 28mm carbs in lieu of the 32mm, so hopefully I make the 32's serve the purpose by adjusting the jet sizes.
Also, any comments on the subject matter will also be welcome.
Thanks,
Johnc
