My T-maxx is having issued with the glow plug. Originally i was only getting one run then i would have to replace the glow plug. I just installed a new glow plug and the EZ Start is showing the glow plug is out

Any suggestions?
 
I was going to ask a question about this myself. I am new so be gentle haha. I have a 2.5 tmaxx as well, and the first few runs were fine. Lately it's taken forever to start, and now I don't know if it will start at all, it's sat for a while, but all the fuel was drained. I don't know what to do. I guess once I get my tc3 on the road I will start playing with the maxx again and sorting out the issues. Just wondered if anyone could point me where to look at this thing.
 
both of you guys sound like your experiencing a rich mixture. You have to adjust your needles almost everytime you go out. Air density changes and so will your tune. Think of the screw and hands on a clock. lean it out one hour at a time, but only after you have warmed it up and brought it back fast. If you dont do a couple of high speed passes first fuel will build up in the cylinder and your adjustment will not be correct. Be sure to start with the HSN first and lean it out until it starts to cut out only at wide open throttle. Bring it back, adjust hour richer and run it again. Repeat this until it does not cut out anymore, then go 1 hour richer. Then use the pinch test to tune the LSN
 
I'm really new, the pinch test? How do I do that? I will have to look through this all again to find these two adjustment needles too.
 
the pinch test is, do a couple of high speed runs again, bring the truck back to you and and pinch the feed line to the carb if it just shuts off its too lean and you will need to richen it up, if it continues to run for longer than 2-3 seconds lean out the LSN(low speed needle) then do a couple more runs, bring it back and pinch the carbuerator feed line, the truck should increase rpms and cut out after about 2-3 seconds. if it just shuts off its too lean and the above steps need to be repeated

Wait I though if it just shuts off it's too lean? And either way you should probably do the test before you lean the LSN anyways.


EDIT: Ayup, found this at http://www.rchobbies.org/engine-tuning.htm

With the engine at idle, pinch and hold the fuel line near the carburetor, cutting off the fuel flow and carefully listen to the engine rpm.

If the low speed needle is set correctly, the engine should increase rpm only slightly and then die.

If the engine increases several hundred rpm before dying, then the low speed needle is too rich and needs to be turned in.

If the rpm doesn't increase at all and the engine simply dies, the low speed needle is set too lean and should be richened or turned out.

Thank you guys very much, I will have to go try this out now. I'd like to have them both up and running tomorrow before I head to work, we will see though.
