Just got back from the lake for the first time with my 69 Sea Ray with 79 165 inline 6 transplant. All went well for the first hour, some stalling issues going from idle. The transision from idle to butterfly opening is rough and had to work a bit (feather the trottle, open and closing rapidly for the first little bit till it "caught") to get things going. Once up to speedit pulled very well and would top out around 37 and cruse at 30 nicely, all throttle settings seemed to be running well. Temp and oil pressure were all in the green the entire time...
Then about an hour in started having issues with backfire thru the carb under heavy load. I could cruse at around 10 MPH or so with no issues but any harder or on acceleration I get a loud backfire thru the carb on a regular basis. Idle went down as well, barely sustaining idle and applying throttle was very difficult without stalling. Got back to the dock and tried working with the idle with no success, original setting seemed to be the closest, any further on the idle screw and it died out.
Thoughts???
Thanks,
Steven
