A buddy of mine had a brush-less motor RC car at work. I was immediately in love when he tore from the gravel lot at like 50 mph over the ditch and across the like foot high grass field and just going faster!! So we saw on Facebook someone selling a used T-Maxx for a good price with accessories! So I picked it up! I got a T-Maxx RC Truck with a 3.3 motor in it, and a Radio. It came with a spare 2.5 motor in a little tool box with a few odds and ends parts including a glow plug igniter. All I needed was a Battery and charger for the E-Z start wand. So i went and ordered one online, waited a week to get it, charged it, couldnt get it to fire! The Glow plug light wouldn't even come on; on the wand. We tried the Glow Plug Igniter instead and it still wouldnt fire. So we trouble shot that, and determined the Igniter was bad, and easiest would be to just get a new wiring harness for the E-Z wand. I went back online and got one with a new E-Z wand just to rule that out as well. Also threw in a new Glow Plug and Air cleaner.
Wired it all up another week later, and today she wouldnt fire!! So i watched videos, downloaded the manual, tried just about everything I could with no knowledge of these Nitro RCs. I decided the motor and frame was horribly dirty, and greasy, and that it needed a good tear down and cleaning. So i watched another video, and used the 2.5 for practice. Tore it all the way down, and cleaned it out, put it back together and felt ready to tackle the 3.3 motor. I tore it down tonight. Cleaned it up really good and inspected all the parts.
Brand new Glow Plug in the head. Copper ring for between the head and jug. The piston was minor black on top, no blue color or major burns on piston, exhaust port, or inside the motor. The Cylinders sleve is shiney as could be with no marks or scratches or anything and it spins really nicely. It had compression when it was in one was piece. The Clutch and flywheel, and all the bearings and o-rings look good. I just need something to lube the motor with really good before a final assembly tomorrow. So i have it "dry fit" together, and i understand to star pattern and use equal torque on bolts for the head and other pieces.
I dont know these carbarators at all, i only know the motor becuase of my dirtbike and auto mechanical background but i feel enclined enough this wont be a problem. The Carb is cleaned as videos say, and i set the High needle all the way in and backed it out 3.5 turns, and the low needle all the way in and backed it out 2.5 turns as one video told me thats where i should start.
So tomorrow i will fully assemble the motor, and put it back on the chassis and be trying to fire it again. Can anyone give me some tips as to why i can't get it to fire and how to get it to? Previous to this cleaning I tried the priming method, non primed method, and all i ever get is turning over and turning over and no fire...
I would eventually like to get this part down, you know STARTING IT and driving it, and eventually doing any types of upgrades i can!
Can anyone help me? We do have a hobby shop not too far away, they charge more then the internet where I've gotten these previous parts, i dont want to have to take it in there and ask them for help unless i absolutley HAVE to because everythings an arm and a leg....
Tips? Tricks? Advice? DO's & DONT's, Anything would be GREAT!! Thanks in advance!!
