The car looks nice enough. Is the fuel tube on the brake rod supposed to be there? If I put it on that way on my s710, when squeezing the throttle it would also engage the brakes and cause the engine to stall.
For the running backwards, it sounds like your plug is too hot and your fuel ignites way too early, pushing down the piston when it's still on its way up, and so reversing the engine's direction of rotation. Bad thing. I have a mugen x12 engine, and use novarossi 7 cold plugs. That seems to work fine.
