I posted this problem 3 weeks ago and got some great help. But I need more help. The engine starts ok, but when you run it for about 25mins it bogs down, I pull back the throttle and throttle up it runs, this will happen a 3 -4 times today, within 5 mins. I turned back and ran for another 25 mins and it ran fine, no bogging. I slowed down and it goged at slow speed once. I ran for another 2 hrs with no problems. Since my last post I have changed the water pump, thermostats, Fuel lines and bulb. Even taken the ball valve from the fuel line out. The only thing I can think of is to rebuild the carbs. Am I going in the right direction. Any and all sugestions will be more than apreciated.
