The motor was running great for the last 3 weeks, then I put it up for a day or two tried to start it, it started rev real high I shut it down now it wont start..


For the last 5 days I have been trying to get this thing to run right.. No luck..

Now in order for me to start it I have to hit the trigger on the controller put my finger over the intake hole and pull the cord.. It starts then dies out once the gas is burnt out.. So I came to the conclusion that no fuel is getting to the engine.. I changed fuel lines, check.. Cleaned carb, check.. Dont know what else I can do..

I am new to the world of nitro burning fun...

Thanks for the reply.. I changed it 3-4 times now.. I got it started but it still revs real high and no matter what setting I set it at it doesn't really work.. Maybe it's a air leak.. That is my next journey.. Air leak patrol..

Have you tried the Air Leak test yet? The mac .28 I have blew holes everywhere and once I sealed it,,,,, holy crap,,,, what a monster! Ended up putting a Dyn .21 Mach 2 and am keeping the mac for a back up engine!

I'd also check the pipe/header gaskets. Check the fuel tank for damage along with the o-ring on the lid.
