My 78 2F stock carb and dizzy, has been running poorly. Timing is good. Symptoms: - Flooding after shut down. Need WOT to start motor. Wants to stall for about two mile after restart. - Very smelly exhaust during acceleration and deceleration. - Poor acceleration. Seems like its running rich. Smells rich. After I shutdown the motor the fuel bowl drains after about 5 minutes. Fills back up quickly upon restart and is right in the middle of the sight glass. After about 2 miles, it runs fine besides the smelly exhaust and poor acceleration. Any ideas?
