I got a ofna Mbx with a Hyper 21 pull start. THe pull start broke so the guy at the hobby shop said no biggie, just take off the pull start and round rod that has a hex on it and you can run it like that, just use a starter box. So i did that, I went so far as taking a rubber plug and super glued it over the hole to keep out any dirt...so i put it on the starter box and it fired up and ran great for about 1/2 tank and then it died...was weird cause this motor has never just died except for out of Nitro. So i checked and it had 1/2 tank left and Now I cant get it to restart.
I took out the glow plug and it lights up bright, I even tried another Glow plug that also lights up bright and it wont start. I have primed the motor a little like i usually do and nothing. just seems like it is dead. Does anyone know what else to check...there is fuel in the fuel line too. Seemed like me covering the hole to the starter maybe messes something but I am not sure...

Let me know your thoughts guys

well i would do is take it to the hobby shop and tell the manager that your employe told me to do this and it doesnt work any more and see if they can fix it for free or give u a new 1

You should have just left the assembly on there, including the hex shaft. I have a Hyper 21, which came with the pull start....after it broke, I just used a starter box on it, without taking anything off. You might have sucked that little plug you made, into the motor....which would be horrible....since there is a tight vaccuum created, when the motor is running.

I would check that little plug, and just take it out if you can, and reassemble the pull start back. If the hole is not air tight, you will have an air leak, and most likely be running too lean. Just put it back the way it was, it probably threw off your stock settings as well. Good luck!

also check make sure u still have good compression if it doesnt
i would go back nd jam the motor up that guys *****. lol ,try doing what that guy said put the pull starter back on.

I saw what RCFreakInFL wrote above and I figured out what I think the problemo is. I took out the round rod with the nut on the end of it and put a plug over the hole, not in the hole. IT did come off while I Was hauling butt around and the same time it quit running. I never put two and two together until what RCfreakinfL wrote..After Work tonight I will attempt to epoxy the plug back on because I think I am sucking a crap load of air through the hole where the rod was sitting before I removed it.

Thanks dude
