My Blaster bogs out and/or dies (in neutral) after the throttle position is roughly 1/8 opened. I've cleaned the carb twice, put in new reeds, cleaned fuel weiner and filters, new air filter....I'm stumped! It's a 2000 model and has always ran fine. The oil pump was removed and I do pre-mix in the fuel. Will the throttle switch and/or carb switch cause this?
