Default Lack of Compression

Ok, so i have a Duratrax Street Force GP and it has been running fine except for air pockets in my fuel line. I replaced the lines to the engine and exaust. Now when i pull the starter cord the few times it feels normal but on the 3rd or 4 full there no compresion or resistance from me pulling the cord... any ideas?

It could just be a slipping one way bearing. Is there any resistance at all? Are you spinning the crank when you pull the cord, or just the starter?

All you need to do is remove the starter CAREFULLY, and polish the shaft that contacts the one way. Clean the one way and reinstall the starter. If it still does it your probably going to have to look into a new one way bearing.

Air bubbles inside the fuel line can sometimes mean that you have an airleak somewhere, but i never found this to be true.

You have to realise that these DTX engines don't last long at all. Mine lasted around 1 gallon and the liner was toast.

www.nitroreview.com have many reviews from people that have owned this engine. You will find that many weren't pleased with how long it lasted.
