GXR28 pull start won't retract

[BigN2000]

Ditch the pull starter. Over time the spring will get weak and won't work anymore. Get a sullian tiger drive and problem solved. Beat Your Truck - TIGER DRIVE STARTING SYSTEM - PRODUCT REVIEW

Which model number will I need?
Thanks

Yes, the reason why is because GXR uses a 3D starter system, it does not use one way bearing and it will be a lot harder to adapt.

No it's a cam type.

 

[alfredwong2003]

Moving freely right up to o-ring, it does seem a little easier to turn on but not sure if the spring in the pull start will be able to spin it quick enough for me to pull again

When I looked at your pictures more carefully, the small O ring is not supposed to be sitting inside the backplate, it should be outside.

I bet you never own one of those engine.

I bet you never own one of those engine.;

I never would. LOL I only run OS, Ofna, Traxxas, Associated and Zenoah
If I did; I would convert the starter by any means; find a back plate that would work or machine one to work and standardize it to 8 mm shaft. This is why the engine is discontinued.

Definitely inside I'm afraid, sits in a groove and would sit on shaft moving away from backplate if it was outside.

Maybe the new pull start is the only way and hope the spring is strong enough to spin the shaft back in

Actually, a lot of OS engines Traxxas, OFNA engines are also discontinued.

Well, have a good clean and lubrication, make sure you don't use WD-40, it will eat the plastic parts. I haven't open my engines again, but my memory said it was outside.

I'll have to look at that, no idea what it is ?

And all the engines that I have most are bump start and one's that have pull starts I can adapt to sullivan tiger drive. I have enough parts to rebuild all 100 of my engines one time over. Box's and box's of engine parts.

This is the other way to start a nitro engine. You bump the flywheel to start.

Yes, you are quite right, the small O ring is inside, I have just opened my engine up and checked. After only 45 years in nitro, the age and smell of nitro have caught up with me ?.

Thanks so much AlfredWong your help was invaluable.
Tuning is the issue now ?, I think the o-rings in the carb are past their best.
You hardly have the specs for them?? ???
