Thank you, Quicksilver, for joining in. Been raining here which is a double whammy... curtails my outdoor activities and usually interferes with my wifi signal. I choke, start the engine, immediately push in the choke lever and let the engine warm up a minute while I untie. When I apply throttle, the revs pick up for a second or two then drop off, then pick up again and drop off. What my father used to call "Kangaroo Petrol." Things don't improve until I'm close to wide open throttle. I don't get the feeling it is going to die. And with no demand on the carb, running at a constant half-speed, it runs rough. The problem does not eventually sort itself out. If the engine is warmed-up, I usually just gun through the mid range and run at speed. In the beginning, I cleaned and rebuilt the carb using a rebuild kit with new jets included. I switched over to an external fuel tank, so new tank and replaced all the fuel lines between the tank and the fuel pump. Bought and installed a new carb and fuel pump. I'll be the first to admit that "new" doesn't always mean "set-up and in good working order." But I can take a look inside and check the float. No ultrasonic cleaning capabilities here but I have carb cleaner and compressed air. Tony, do I have to pull the fly wheel to check the resistance on the exciter and trigger coils? Thanks, guys... Bry
