picco 26 revo

hey guys im new here and i have a picco 26 in my revo and i have a problem. everytime i give it all the gas at one it wants to die but if i build up the speed. like 25% throttle at a time then it works. what is the problem.

It could be something restricting the fuel flow. I had the same thing happen to me. It ended up being a slightly pinched line.

check the carb settings. the high and low needles might be too rich or too lean.

the fuel line is good but i havnt checked the carb settings

where r the carb settings

[jdtmaxx]

they should be on the carb. there are factory settings for different engines.for instance the high speed needle should be 3 1/2 turns out from closed. and the low speed should be about 1 1/2 turns out from closed. and does it idle real low. if it does ,raise the idle.
