I have a Trinity Picco .12RE that I am running in an NT1 with a Max power 2649 pipe. It only seems happy when it is running temps > 270F. The problem is that if it stalls I cannot restart it. It will not draw fuel. After 10 - 15 minutes cooling it fires right up.

I am using Byron's 30%(which everyone else is using). I did put the extra shim in the head. I have sealed the carb for air leaks. There is a small leak at the front bearing (just air when I pressurize it, not fuel when it is running).

This is my first nitro engine so I have no clue. It has stumped the local guru. I am just trying to make it through the last few racing days of the season and will replace it next spring.

Any thoughts or suggestions would be appreciated.

Regards,
Carter
