Dynamite .19 Tuning Issues ?!
 

Hi, I bought a dynamite .19 mach 2 engine over the summer of last year and it was running amazing.Fast forward to today and it wouldnt run idle screw didnt do anything, So i just stopped set everything back to stock settings and fired up ran for a little then was blowing glow plugs left and right. Now i was getting frustrated and i think its running lean but i do not know. Engine is fully sealed and i dont see any air leaks when i do a leak test with soapy water. my real question is where else do i begin this is the only motor thats done this too me and it has less then one gallon on it and i do not want to give up on it.

have you replaced your fuel lines? confirmed that the needles are not plugged or partially plugged? fuel tank leak test? what is making you think it is running lean?
if it is set to factory settings, that is really rich, and will have a tendency to blow plugs. are the plugs just not igniting well anymore? or are they physically damaged? (coil receding into the plug body)
