What a disaster
The 18ss engine is worth nothing for racing. Mine stalled in the first 3 minutes in the first race. I wasted 3/4 gallon of fuel in 3 hours trying to get it running good.
The temps would be fine. When it got up to temp (250-260), after a good full throttle run while idling the engine would rev up for 3 seconds or longer, settle to a good idle and then stall out. I screwed with every needle but never could get it running. I cut the clutch...everything.
I don't know what to do, sell it, get a new engine or convert it to electric.
I used 25wt rear with the shocks in the outermost hole in the arm (of the 3) and used 30wt in the stock front arm location and for how it ran, I could keep up with the 3 diff truggies. I put about 1cm of fuel tubing as a down travel limiter in the rear shocks. Tubing in the shocks also help the shock ends to not pop off when the car land on it's lid, the impact is softer.
Maybe your running too lean since you have it rev up in idle? Did you try factory settings?
I had many good runs with my 15. The other day however it kept stalling on idle.. I adjusted the 3 screws and it times at seemed to help, only for it to stall again when giving full throtttle, I cleaned and kept adjusting it, but nothing helped. When I came home I discovered the exhaust header had come slightly loose from the engine block. I think this was the problem, and I hope not any dirt got inside.
Usually I never have any problems like this, and it always starts up and drives like a dream.. I try to keep it in mint condition by cleaning it often while running, using afterrun oil when I get home, aswell as cleaning airfilter and car at regular intervals while running. I'm also very very careful with dirt, and clean the entire motor completely before removing airfilter or glowplug with either denatured alcohol and a brush or bicycle cleaning spray and an air compressor. After a thorough cleaning I use car "bumper black" from Motip to make the black platic parts like new.
