They were set out 6.5 and 7.5. I have done a lot of work rebuilding all the carbs including new bowls and float assy. 4 of 6 bowls were cracked.
When I bought the boat it always had a fuel smell, but the guy told me they changed the fuel line from the tank and sending unit, and the smell was from that. Needless to say further inspection I found many issues. fuel fill and vent hoses were leaking, and that was the bigger issue with the fuel leaks. Changed them flush the hull numerous times and no fuel smell. Replace the VRO, primer(both leaking, rebuilt all the carbs, replaced hoses and clamps. no leaks by the motor. New plugs and good spark (I checked spark today). So I have another string talking about the sputtering at low speeds. And I found the battery switch had failed and was not making good contact so the engine was not getting full power. The battery meters showed 12.8 -13.5 VDC. But yesterday it would not start like it had a dead battery. Long story short I traced it to the battery switch. I replaced that and the engines is running better. I did not get it out to the water for a good test yet, but atleast in the test tank she would idle without sneezing or coughing..... If I would have checked the spark before I fixed the switch I bet it would have been weak..... If I ever have a problem like that again (Hopefully not) I will check spark as one of the first checks. Thanks
