Thanks Tim
Sounds like a plan for me may be to buy the ums upgrade carb. I can't make the intake adapter and sounds like they have done it for the upgrade carb.
Do u feel the upgrade gives the motor more power as if starving for fuel with the OEM carb?
The starting and running charistics of my motor are very good
i run it on 10% methanol/niitro 10% syn redlne.
it idles, transitions and runs full tilt without a glo driver.
