Well I did it finally... thru a combination of... bad... handling, speed, location, luck & yes, stupidity... I managed to render my RS4 useless.

I drove it UNDER a dumpster with say 2" of clearance ( ouch! )... 1/4" more would have been fine!

I tore the lid clear off the fuel tank ( thus tearing a hole in the top of the fuel tank )...
I broke off part of the pipe ( the end of it where it attaches the the chassis... ( I think I can save it )...

AND

AND!!! I broke the high speed needle off just below the fuel intake... ( double ouch! ) Carb is now useless.

There was no damage to any of the drive train or steering that I can determine... but I have a steering handling problem ( obviously ) I need help with.

SO!

I am in need of replacement parts...

From the top... should I buy the same stock fuel tank? ...or is there a better one? suggestions....

I'll ignore the pipe for now...

Should I buy a new carb? Or just grab a whole new engine? The engine has 1/2 gallon thru it... If just get a new one then any recommendations...?? NOTE: I am looking for an engine with more low speed qualities ( response / power at the low end ) ...lighting fast speed is useless around here... no tracks or big parking lots to utilize blazing fast speeds...

If I buy a new carb I know I will be retuning it from scratch, but will I have to do any kind of breakin?

Suggestions anyone?
