I just got a Mad force Kruiser 2.0 and am just about through the break in processes but seem to be having some issues and not sure if they are normal. The spur gears just got whipped out because the bolt holding the engine drive on keeps rattling loose. Do I need to put a little Loctite on that bolt and is it difficult to replace the spur gears.

I am not familiar with your specific model but on all my rc's the spur is relatively easy access and easy change. Blue loctite for metal on metal is ok.

Thank you for your feedback. I really do like this truck but it sure likes to fall apart every time I take it for a run, beyond what I would consider normal. And it is extremely hard to start.

Post a picture of what is coming off often. If it's what I think it is, a dab of blue loctite will fix it. Do post a picture to be sure.

I will post a picture shortly, any idea on the hard start. I have to pull it 30 times to get it to purr.

The list is long that can contribute to a hard start. Under primed, over primed, poor glow driver charge, poor glow plug, incorrect needle settings, incorrect idle gap setting, loose engine screws (head, backplate), etc.

If you have reasonably close settings on the needles and idle gap is .5-.7mm, then try this: fill fuel tank full. Remove pressure line from tuned pipe (that goes to tank). Blow into pressure line until fuel reaches the carb - blow one more second. Connect pressure line back onto tuned pipe. Connect glow driver, and hold transmitter while trying to start the engine. If you give it about 5% throttle (so throttle opens just slightly) when you pull the starter, it should fire right away. If you have to hold the throttle open slightly every time you start the engine, the low speed needle is too rich. Lean it in 1/16th turn increments until it starts better and idles nice/transitions to high throttle effortlessly and without a ton of blubbering and smoke.
