The "wobbles" are normal, what I've done was fine tune that inner nut. Not too tight, but enough to minimize my "wobble". To insure I did just that, I press against the spur gear, give the motor a little gas and just repeat pressing until you see it straighten out. I have my wheele off for all these tests. Next is my pressure between the spur gear & the pinion. I was taught that you only need like .005 in between gears. Press your trigger & you should hear just a fine hum (not from your motor). Fine tune that by just snuggin down the first motor bolt, Leaving the top bolt loose you should easily be able to move back n forth the motor, hence, fine tuning your gap between gears. Once you got your desired hum & bite (tire wise), just tighten up that top bolt, follow through with that second, DONE. Follow?
With this you should'nt have any issues. I'm still running my kit spur gears. I just follow the above EVERY TIME I get done running. In fact, my opinion is I'm just warmming 'em up, cause now I'm a true contender, just carvin my lines and have'nt even thought about burnin my gears. So I hope this helps my brotha F104er.

To get a good mesh between the spur and the pinion, some people place a piece of paper between the two, then tighten down the motor.
Thanks for the tips guys. I have been doing all of that, unfortunately. Perhaps I should have also said that from time to time the motor will also move toward the spur gear and bind it up. I have run a lot of offroad and taken some big hits and never had the motor move so much. With the F104 it seems that if I even roll the car the motor moves one direction or the other and either destroys a spur or binds the mesh up so bad that I can' drive it.
I am considering getting the Aluminum bulkhead to try. I fear that the plastic one is so smooth and is has trouble providing enough friction to stop the motor from moving. All my offroad cars all had an aluminum motor mount.'
We'll see and I will let you guys know.
Thanks again.
