Dave: Fuel comsumption is not bad. Throttle response is super fast. No adapter....redone head. TKG: I have no bigger glow carbs on hand. I used Omega Castor/Synthetic 10% Nitro Glow fuel with way to much oil in it. I guess I may just cut the Glow fuel with gas....and try that tomorrow. Capt,n...Over and out! P.S. I will also try a Walbro....I got 14 of them...but got to sort out a good one.
