I just received an Ofna Ultra GT LX rtr as a gift and I am having trouble starting the engine . It ' s an ofna force . 21 engine . I got it started once and I let it idle with the car on a block for a few minutes then I shut it down as the instructions said . After it cooled , I tried starting it again and nothing happened . I ' ve checked the fuel lines and air filter , changed glow plugs , checked glow starter , adjusted the needles and checked carb opening and it just wont start . Is there anything else I can try ? Any help would be greatly appreciated as I am new to nitro .

graym - Do you see fuel going into the carb . Sometimes the needle needs to be open more than the manual suggests . If not open the high needle another turn . Also prime the engine before starting . With the glo - starter off bump the engine with the starter box and hold your finger over the exhaust , about 5 seconds . This will pressurize the tank and push fuel into the carb . Then try to start it with the glo - starter .

GregV - Thanks for replying to my post . Anyway , I did prime the engine beforehand and fuel was definitely entering the carb . I e - mailed Ofna and they said to try leaning out the low end needle . I ' ll try that tomorrow or whenever I get a chance . Hopefully it will work .

Thanks again
