Yeah i've tried many different idle settings to start it, and it doesnt help. Also, for some reason the pull start is incredibly hard to pull, compared to my last engine. I'm assuming it is when the piston is reaching its highest point and there is pressure in the chamber. When trying to start the car, and im pulling the pull start cord all the way out, it doesnt allow me, only when i slowly pull the cord, can i get it all the way out. When trying to start it and im pulling it fast, i can only get it out about 3 or 4 circuits of the piston.
