Default Mach 28(big red) tuning issue

The motor maybe have about 1/2 gallon of EB MODS(20%) fuel on it. I only raced it at Motorama in Feb and it was put up afterwards. It ran perfect for the race. I have it in my Losi XXL. I went to start it 2 weeks ago with new glow plug(mc-59) in it and with ignitor on it would idle and let me give it 1/4 throttle before shutting off. It cuts right off after I take ignitor off. Dont have a clue what could be wrong with it. Any ideas?

My advice would be to set the hsn and lsn back to factory setting and re-tune it.

I know my girlfriends rustler did the same thing, it would stay running while the igniter was on it, but when i took it off it would stall.. i wanna say i LEANED the LSN a little, and it solved my problem.

You just described the test for a weak glow plug. Time for a new one.
