HELP! Nitro OS MAX .40 FSR not running properly
Hello,
I was recently given two models which I am restoring currently. One is ready to fly the other still being restored as it was never completed originally. The one ready to fly has currently fitted to it an OS MAX .40 FSR. I have replaced the fuel tank and the glow plug which I am told is the correct one for the engine.
The problem is, each time I start it, it starts pretty happily around half throttle although it does tend to wonder in rpm. If throttle is increased it can either stay running or stop. If the throttle is decreased it will stop. I can not get it to sit at a suitable idle. Please help!
