Hi all, got a few probs with my old r-c. Firstly, its guzzling petrol more like a V8 rather than a 2ltr, 2ndly its idling really rough and 3rdly, i cant damn well fix it!! I've mucked around with the timing and idle mix screws, which fixes it for a bit, but the idle mixture screw is now turned all the way in and that cant be too good! What i think is that i jus keep on adjusting the idle mix to suit the rpm with the timing crap, which is causing all my fuel probs. The car runs fine, its jus the idle. How do i get it to idle properly and still run ok?? This is pretty dumb, but how do i PROPERLY adjust the timing? as in all that 7deg BTDC?? I dont understand any of that, i just line up the 1st notch with the timing light? Any tips would be great!! Thanks guys!!

Sounds like your carby needs a rebuild.
Also, go out and buy a manual for the motor.
One of those Gregories ones.
Tells you how to do all kinds of stuff.

Does the manual not described what BTDC is?
Should do.
If not, a quick search of google will reveal it.

TDC= top dead centre.
BDC= bottom dead centre
So i would assume that BTDC= bottom top dead centre
hope that helps. As for setting timing it is important to find TDC and then make sure that ur marks are what they should be, ei, find TDC then make sure the 1st notch lines up with the ur reference mark. advance the timing accordingly.
Also buy a cheap carby rebuild kit from a parts store. Fuel miser make one for the 2t carb which cost around $40. Should be very similar for the 18rc
I am 16 and a complete amature and managed to rebuild my own 2t carb in a few hours, failing that, take it to a carby specialist.
If u decide to rebuild the carb urself, CRC make a great product called carby clean(pressure pack), this will clean the parts of ur carby much better then most other chemicals.
