I am in the process of break-in on my 3 port race. I have ran 4 tanks through it while heat cycling the engine. I am getting 3 cycles per tank. What I have started to notice is that on tank 5 it dont want to stay running. Im getting plenty of smoke and temps are at 215. When I go about half throttle then let off and then give it gas it dies. It does not have this problem when I leave the igniter on. Im thinking I may be a little rich but im not sure. The motor was modded by Rick Brake. Any advice would be appreciated. Thanks in advance.
