You might want to try a Dynamite 007 HT, I am running a modded S7 with
WS7 crank ( basically a WS7 ), Bryons RACE 25% Gen 2 and I am easily getting 10+ minutes on different tracks I have raced at. This is in my
Losi 8ight 2.0 buggy. Temps from 200-230f

I own a RB C6 BB L2G with a 192 and 2045Exhaust, but I'm having trouble finding the right carb settings.
When I use the stock settings (HSN : 3.5 turns from closed, Idle : 5 turns from closed), I don't know which setting for the LSN to use. Should it be flush ?
Or could someone post their carb settings, So i can see where I have to 'aim' at.. I'm desperate
Sorry for my crap english, it's not my mother tongue ;-)

adjust yr LSN to 5 and yr idle gap to about 0.7-1mm...

and tune from there.

I have a WS7 and have done a full rebuild on it .
The engine is really sluggish down low and then hits a power band at half revs .
It flames out all the time .
It has new bearings and the carbi and back plate is sealed .
Plenty of pinch and compression as it is new .
WHAT IS WRONG , PLEASE HELP

I'm using the RB 2045 pipe with the 198 header combination
I tried an OS P3 plug , it helped a lot but still the same end result
It can flame out at any time , mainly in the pits . to get it running and keep it running when it is cold is a nightmare .

If it flames out during pit stop 99% of the time with ws7 or C6 the bottom end is to lean. Really have to run RB's on rich side on Bottom end. When you say it was hard to keep running when it is cold. The C6 & ws7 should get up to temp of 180 or so very quickly if they do not they are not tuned right. I have ran C6's at the Nitro Pit in AZ when it was 110 degrees in the summer and ran the same C6 in So Cal when it was 55 degrees and tuning was changed an hour or 2 on top and temps where exactly the same. Just have to find the sweet spot on the Carb.
