So I bought this kit new.
It came with a Carson .15 motor (Don't think it was the original motor)
The air filter is definitely too old to use. So I ordered a Motor Saver air filter kit.
I also ordered a CVEC tuned exhaust pipe.
Just need to order an exhaust header, glow plug, fuel line and a fuel filter.
Plus I want to replace the hubs the wheels attach to.
They are the kind that do not have pins and I hate them.
I think I can substitute some kind of Tamiya hub so I can use hex's that slide over a pin.
Here are some pic's.
