Here is a update, I took the Nemesis out for a tuning session with the OFNA check valve with some good results. I ran a couple of laps and it seems it was running to lean because it was runnig eractically. I turned the needles back to where I had them before I installed the check valve and started to turn the needles 1 hour at a time and found a setting with a good tune. temps were around 230, so I think I will lean it out just a tad more. I still cant seem to get the thing to idle with out stalling and when it does stall the carb is loaded with bubling fuel, dont know why this is happening or is this normal with the check valve. Overall I am pleased with this check valve and enjoy the longer run times than with the small tank I had installed previous. I was having a good time and you know it's not rc unless somthing breaks and sure enough, I broke the rear axle.
I have already upgraded the front axles but not the rear. Looks like I will be ordering a pair from www.customrccars.com. Any help with the stalling issue and the carb filling up with fuel issue will be greatly appreciated....Thanks
