Hello all,
Im a new member and also a newer r/c owner of a used 3.3 4909? t maxx owner. I bought off craigslist for $150 non running. The guy said it was just running before i met him and when i met him we tried to start to no avail. although it did pop off and tried too twice very briefly it didnt start. the ez start battery died and i assumed i could get it running. ( a little background on me i owned a t maxx .15 around 2000 or so and had it for about 6 monthes and it was stolen along with a car i used to own a nice 87 monte carlo ss mint--long story anyway still painfull) so anyway i do have some experience and i never got back into it untill now and heres the thing:
When i got it home i noticed the clutch was sticking partly out of the cluch bell so i apart and it was broke and fried, did some research and understood it was engaged and that may be why it wasnt starting. (ordered and replaced)
still nothing no fire no pop no nothing.
He had some spare glow plugs in the box i tried a few different ones they seem to glow fine when i ground them out on the block, also am getting plenty of fuel, reset needles to factory 4 or so out on hsn and flush with low speed, and idle screw idk where its set but dnt think that matters to start. carb is adjusted approx 1mm open.
So Fuel, spark, air, hmm.. only thing left is maybe compresion? i couldnt understand how he had it almost firing and when i got it nothing. ive tried everything. Also after whatching TONY's VIDEOS on you tube(thats why im here now) which were great by the way, i tore down the engine i would say half way. I tookk head off cleaned a lil, took back plate off and cleaned a little everything in motor seem intact nothing cracked working smoothly. Seems to have compression with glow plug in, when i turn by hand makes thunk noise.
Also one way bearing locks in turns motor over fine. and one thing i did notice when i took of easy start by the one way bearing it was noticiably wet in there, dont no why is that rear bearing leaking fuel,oil? that shudnt keep it from firing thought would it?
Last thing i dont no how old it is, i beleive it ha the grey transmission and it has a reverse servo with old 27mghz radio. so 4909 maybe 3-4yrs old? so the thing is, the easy start battery doesnt last long at all and im thinking the glow plug isnt getting hot enuff, maybe old fuel?
I am stumped i tried everything i think i can do for now. I almost bought a new motor yesterday, however, not gonna give up untill i no for sure what it is. i also just ordered 100$ worth of parts(new 2070 servo steering-hump pack battery,new style tuned pipe chrome,replacement bulkhead and bumper,shock oil, air filter oil, and body pins,) so now i got about 250 into it and if i do need a motor not going be very happy because then ill have about 350-380 into it. grrrr. could have gotten something near new. oh well either way with tony's videos eventhough its a for .15 i will be able to deconstruct and clean and make look new.
SORRY SO MUCH TEXT. I DID ALL THE RESEARCH ON MY OWN AND GOT AS FAR AS I COULD BEFORE REACHING OUT. LIKE I SAID I AM STUMPED IT DONT MAKE SENSE. PLEASE HELP AND THANKS FOR YOUR TIME.
