Hi guys, im fairly new to RC and i bought a CT-5. After i got it i decided to upgrade to a RBInnovations air filter and i also added a hyper valve for the fuel-to-exhaust line. Now it will simply not start regardless of how lean or rich i tune the motor. It will start and run idle for 2 seconds, then it will accelerate by itself faster and faster for 5 seconds and then shut off. I have checked the glow plug and its fine. I prime it to the right amount and i dont see any leaks on the fuel lines. Any help will be appreciated.

Is the fuel geting to the engine?

Sounds like you might hav the Hyper valve in backwards not allowing exhaust pressure into the tank leaning it out and finally stalling. try reversing the valve.

Yes, the gas is getting to the tank and Yes, the hyper valve is correct. They illustrate the direction it should go very clearly on the instructions that come with the valve.

Still there is no harm in trying to reverse the valve or removing it to see if it is some how related to the valve. If you are still having problems with the valve removed then you will know that it isn't the valve and the problem lies elsewhere.
