I'm in the process of dremeling off the square drive. Part 70075. This is way more of a headache now. I hope when I get it off, I will at least know what the problem is.
 
Ok, got the drive off. Definitely signs that the screws were not secured down. Marks all around the shaft.

Also got the spark plug out. That was pretty black. Should I clean it or just replace it?

Also, anyone have a spare square drive they want to sell??

When reinstalling the squares, make sure the set screws are on the flats of the shaft. If not they won't hold.

I like to dremel an indentation on the flat to give the screw more to hold. Not necessary, just some insurance.
 
When you get that problem fixed and if you haven't got the turning fixed you need to turn the duel rate all the way up .I had the same problem with my truck and that fixed it..good luck..
 
Just an update, thank you everyone who gave me great advice and especially rcgasser who was gracious enough to send me the part I needed. I'm back up and running. Truck is working good.

I put in my new NGK spark plug and the engine has some balls now. Guess I can lean it out a bit as its too rich at take off and bigs a bit at wot.

How long do the plugs actually last?

Glad to hear now have some big fun.
 
I ask as after only 4 tanks, that stock plug was burnt. I'm using 25:1 royal purple. Should I lower it to 24:1 or lower?
 
25:1 is fine...the stock plug from China is pretty cheap...a lot of people burn it out during break in...once you twice it with a normal cmr7h (if memory serves) it'll last quite a while
 
Throttle stuck and went out of control

Has anyone had an issue where the throttle stuck and took the car out of control? My truck luckily hit a wall out of control and became unresponsive as it almost hit some kids playing nearby.
 
Yes it`s happened to a lot of us.Now you know why we advocate getting a kill switch.The failsafe in your radio whatever brand your useing is useless.
