Guys thanks for the info you posted. I just may order that Nova carburetor but just for the heck of it I tried something. I had a rotary carb that I new worked well on the motor it was on. It had a 10mm mounting dia (pretty common) and had a venturi about the same size as the trx carb (6mm). I was thinking today of making an adapter to bond to the 10mm carb and it hit me to cut the neck off the bad trx carb and drill it out to 10mm and bond the 10mm carb to it and so thats what I did. Turns out the trx carb has a metal sleave in the neck that is 13mm outside dia and you guessed it, 10mm inside dia. So I cut it off the trx carb right at the base and bonded the 10mm rotary carb into the sleave, did a little grinding and polishing to make a nice taper and bam.......the motor runs great! Very stable and consistent and seems to have the same power with a smoother transition. I will race it this saturday and really give it a test and let you know how it turns out. Thanks guys.
