problem with ez starter and motor tmaxx 3.3

[kayll]

Got a T maxx 3.3 and have some probs with starting it. For a while ago i had to swap out the piston/sleeve. Got everything going and did a proper break in, but now i´m having problems starting it.
I got a new fully charged battery for the Ez and a new glow plug but when i´m going to start it turns the motor around for about 2 sec then it stops and the ez can't turn the motor any more.

Yes i have checked if it gets flooded and when i take the glow plug out and try with the ez again it slowly turns the motor. So i have taken the motor of and the ez start thing as well and when i plug in the ez motor and just spin it around it without it attached to the motor it works fine it spins around fast and sound good to. So i reattach everything again and try, but this time it spins the motor around no prob. But when i connect the fuel lines it turns the motor around and he starts no prob, i let him idle for a while but as soon i slowly accelerate he stalls even when i hold the maxx in the air.
And then i try to start with the ez again the motor turns for 2 sec and it can't turn the motor around any more it just clicks.
I take the glow plug out and check for flooding, try with the ez again but the same thing happens again it turns the motor around but very slowly untill it can't turn it at all...

Again i take the motor off and do the same procedure as before and it works again, i reassemble everything again and it turns the motor no prob.
So reconnect the fuel and it start again no prob this time i tried leaning the fuel a bit. it idles fine but again as soon i try to accelerate it stalls and does the exact same thing again!..

So why I'm i having this problem i have no ideas left whats cosing it to not turn the motor. And when i try spinning the fly wheel its a bit hard but not stuck..

Help me please

Is the one way bearing slipping? When the engine turns over slow, does the ez start motor sound like it's turning at normal speed?

I had so many problems with my ez start too. I dumped it for a pull start!

Exactly dump it for a pullstart alot less weight and easier just carry an igniter with ya

Three rhing come to mind for me.

Fisrt is the one way bearing and shaft clean both and put a light grease on the shaft.

Second is I believe it is running too lean since when you start to apply throttle it dies not getting enough fuel.

Third since you rebuilt it the pinch is going to be tight for a while. Loosen the glo plug a little so the compression is not as strong it should still fire up once started tighten down the plug.

I've never heard of greasing a owb. Being that they slip when they are over lubricated, this doesn't make much sense. As for running lean, if the owb is slipping, wouldn't this indicate too much fuel? Pre heat the engine if it's new/rebuilt. Use a hair dryer, and get the engine as warm as you can with it. Cracking the glow plug loose helps to relieve compression, but not mechanical pinch.

Finally fixed it, it was the plastic thing that spins the axel around it had a crack in it so when it got fludded or something the plastic thing just was spinning around that metal thing that you stick the axel through. Haha sry but dont know the english word for thoughs "thing".. Any ways got every thing going well..
Thanks for the replys!

Btw sold my tmaxx and gone electric now E revo brushless problem solved!!

Glad you got it fixed. The reason for putting a very small amount on the one way bearing shaft is so when the bearing is not starting the engine the shaft will spin smoother in the one way bearing. I know it sound wiered but it actually does extend the life of the bearing. When I was servicing photocopiers for a living they had ony way bearings every where and if they were left with out lubrication the would seeze up in no time because of friction causing excessive heat build up. Move this over to rc's they are already hot so by elemenating the friction will make it last longer. No the lean condition is too much air not enough fuel the bearing slipping is due to it getting hot and building up heat and if that shaft is covered in oil is because the rear bearing is leaking.
