Well I just got done running the buggy no luck tried a brand new os #8 glow plug some fuel lines from my savage and also tried putting the hsn needle back to 2.5 im stuck with the same results and im getting pissed. Im not sure what to do hopefully I will go to the hobby shop tommorow and take it under there hands for about a week or whenever they get finished. By the way im using traxxas fuel 20%. I'm thinking since dirt got into the engine and it was burnt on it has affected it but im not sure I guess I got to clean the filter every 1 or 2 runs. well I dont have the slightest clue.
