Hello! I have really big problem with this engine. I had the stall effect and no settings of the carb can make it run normal, but I changed few types of plugs and now works good. But the problem I have is this:
I have very nice acceleration and good finger response, but just only in slower speed. From 1/2 of the throtle to the end its no more acceleration and the truggy goes max with 20-25km/h I know you will tell me to close the HSN, even now the engine goes more then 140-145C, so its very hot enough to lean it more. What elese could be the problem? I opened and checked the piston and slave, they look very smoked, but no scratches or so. I think it could be the carb problem. I have a leak from the one side. Is this a normal hole? When I blow through the HSN it makes bubbles from this hole(when testing with foam). Do you have the same hole in your carbs? Can you suggest me what elese could be the problem that I cant get absolutely no top speed?
