ITS FIXED!!!
If you are having any trouble with a turbo RX1 reglue the T's before you do anything else.
Spray 25, buckeye, RXHALLER, Kip and others all keep saying the same thing. Reglue the T's.
Took the sled to the mountain today. The only thing I did was reglue the T's where they hook to the hose for the pitot tube. T's were tight and did not move at all on the carbs. T's on the hoses looked fine, but sled seemed to get worse the hotter it got. I used Yamaha Bond 4 like I did before, but I double clamped the T's at the hoses. Used a wire tie, plus welding wire like woodsrider suggested.
The only other thing I did was to leave the water shut off to the carbs open.
2800ft elevation, 18F
135 Mains, stock needles, fuel screw 2 turns out, 300 pitot jet. Temperature guage never went above 1250.
NO MORE POPPING under low throttle. I could tell as soon as I started it that it sounded better.
I don't have any 200 pitot jets, but I will feel better with a 200 under 20F.
