T Maxx 2.5 starting issue

[Sethhh!]

so nitro cars DO have to be in a certain gear to start..? and does the bar need to be in or out or centered for it to be right? like.. i wanna at least get the truck started. so where do i need to have the bar? how far in/out of the tranny

i think this servo is done haha i pulled it back out and there's what looks to be some sort of liquid or acid burn on the side and bottom of the casing

No, the tranny would not be affecting the motor. Although it would probably be a bad idea to start it "out of gear" in case the idle is too high and it starts spinning up the spur gear. It might do some damage to the tranny, but I don't know. I just kept my broken shifter servo in my tmaxx, cut the wire and turned the horn so it was pushing into the transmission.

There is something up with your motor, if it is not starting it boils down to the motor. Nothing else on the truck would make the motor not start.

I have never had a problem with EZ-start, however other people have. You could try getting a glow plug ignitor and a pull start. Heck I think it would be worth it to just try a glow ignitor, I have seen them for 10-15 so you wouldn't be out much anyways. And then you would save on the ez start battery too because it is just spinning the motor.

 

[Sethhh!]

yeah i have been thinking about trying the igniter

I really think a video would help, because it is difficult to describe what the engine is doing, what it sounds like, ect. I remember back when I was still new I sat there and cranked over the motor for a few minutes, thinking it was too cold to start but the carb was just way too rich.

Gotta learn somehow.

+1 i also did that... I also put way to much after run oil in the thing and it wouldn't even make a full crank with the ez start.It was like the wand battery was dead.
But in fact it was basically hydro locked with oil so i pulled the exhaust off and pulled out the glow plug and cranked for 30 seconds or so it just pored out oil....

 

[hulkmaxx]

First off, 1. Does the EZ start roll the engine over or is it sticking tight, 2. If it is sticking like andrew said may have to much oil inside. 3. Pull glowplug make sure it is rolling over freely, 4.The one way bearing may need some lube. WD-40 works best. I would pull the oneway bearing off the engine and make sure it is installed with the numbers on bearing facing the engine. Hope this helps

 

[Sethhh!]

motor works fine. its NOT flooded. owb is lubed and right direction. ez start DOES roll the engine, just wont start. I'm thinking it must be the tuning then.i have read all sorts of forums and videos about and thought i had it set right. i don't know..

only other thing i know to do is take it to the local shop and let them check it out..?

 

[Snook Man]

and i re lubed everything. i took every single part apart except the differentials and the transmission

Did you disassemble the engine (remove the piston) also?

 

[Sethhh!]

no, i have not taken out the piston. i got the truck friday night and have already had the engine apart five times though haha i took a video of the servo as well as starting the truck. my computer isnt wanting to cooperate but I'm working on getting them uploaded. how do you post a video on this forum though? with the picture upload..?

 

[madd802]

Upload the video to YouTube then copy the link to here

i got it! haha so thats what the shifting servo does. so i just adjusted as so that it stays pushed back

it spits out a little fuel when its doing that so i assume its too rich. i closed it up a little and nothing happened so i did more and so on and eventually to the point where it just cut off. so again, I'm sure its probably just my tuning

 

[madd802]

Video 1 i would push it in gear and unplug the servo for a temporary fix.
Video 2 I would pull the blue wire off and use a glow plug igniter. Sounds like it wants to start

 

[Sethhh!]

planned on getting an igniter anyways. and the blue wire is just to heat the glow plug right..?

---------- Post added at 4:23 PM ---------- Previous post was at 4:21 PM ----------

and to be in the gear, that bar connected to the servo needs to be all the way back, right.?

 

[madd802]

Yes And i think so for question 2 Make sure you report back with us

 

[Snook Man]

All the way in toward the transmission with the shift rod is forward. Out all the way is reverse. It will have no bearing on whether the engine will start though.

The Blue wire or a glow igniter is only needed to supply’s current to the glow plug for the initial engine starting. Once started the glow plug glows on its own due to a catalytic reaction between the platinum glow plug coil and the methanol in the fuel.

 

[hulkmaxx]

It looked like in the servo vid, your reverse channel might just be reversed.

 

[Sethhh!]

reversed as in..? the box is the wrong direction or the switch on the transmitter is reversed..?

---------- Post added at 6:31 PM ---------- Previous post was at 6:29 PM ----------

one of the few times it actually started, it just started driving on its own. in reverse. and i guess what would be because the servo is reversed haha

 

[Sethhh!]

I'm going to order more glow plugs and an igniter and hopefully it will crank right up. ill let you guys know

switch on the transmitter LOL!

The servo reversing switch on the transmitter could very well be reversed but it all would depend on which position the forward/reverse rocker switch on the controller was in to determine what’s going on...
I didn’t see any glitching in the servo vid. It looks like to me the servo was just trying to find center when the rx was powered up. I assume you did have the transmitter powered up also?
Remove the servo horn from the servo and then power up the transmitter and receiver. What happens to the servo then? The spline should find its center point and then stop. Once stopped, move the forward/reverse switch on the transmitter and watch what the spline does. If it rotates normally (approx 180 degrees) and stops the servo is probably working correctly and it only needs to have the horn installed in the correct position after it is centered. Just watch the spline to see which way it is turning in relation to the forward/reverse switch to determine if the switch is reversed or not. Shift rod In toward the tranny is forward / out is reverse.
