I have a 1987 Indmar 351ci wit
I have a 1987 Indmar 351ci with a Holley 600 cfm vacuum secondary carb. Occasionally at idle the secondary jets are putting fuel in the bowl but the ports are not open. Does any one know what would cause this. Obviously the motor will not idle or run below about 2000 rpm when this happens. What kind of vacuum issue with the motore would create this problem. Any ideas appreciated.
