Just got a 1/8th scale Truggy with an SH .28 on it, the guy I got it from says the engine was shot and wouldn't run. Well even being a complete noob with nitro RC I got it running, now here is the problem, it will run for about 30 seconds and then die, if I hold the throttle open even the slightest bit it will stay running for as long as I hold it... what does this mean?
