Help Terra Crusher prob

[Crushedreams]

I have only a few tanks past break-in on the engine and it is making me mad. First off I am at high altitude (7600 ft.), so I dont know if that has anything to do with my probs. It will only run at full throttle and will run for a few minutes then it loses power and stops momentum and wont move then dies after about 30 seconds of trying forward adn reverse. It is very hard to start after it dies. I ordered a 2 needle carb and high capacity pipe, forward only conversion. Do you think this will help oh yeah I was running 10% nitro, I ordered 30% to mix with the 10% that i have is that ok? 10% is Red alert and 30% is o'donnells R2R. Any other advice would greatly be appreciated.
Thanks Josh

You are most deffinantly running to lean,,,,,, richen it up. Also, I put a two needle on it and I could not get it tuned right, so be careful, make sure you can get it tuned with the origanal carb befor you get a new one.

dont mix fuel! cant help with the other ?'s but never mix fuel

[huasze]

its perfectly fine to mix fuel. it's just that your specs in the final mixture might change a bit. check your fuel line for the TC, and make sure your needle is no less than 2.5 turns out from the most clockwise position. your complaint sounds like you're running the thing way too lean.

I have been running the mixted fuel; half and half 10% and 30% it is running alot better but it still wont idle. what should I look for in the fuel lines?
Thanks Josh

If it won't idle check your engine clutch spring. make sure it is still intact.
