Hello All,
After doing a complete tuneup of my 165 IL6--points, plugs, condenser, rotor cap and checking the plug wires I started and ran the boat in the water. Everything checked out except for what I would call a miss at idle 650-700 rpm.
I borrowed a neighbor's timing light to check the timing. It was off the scale on the tab-I am guessing 12 BTDC. I am supposed to be at 6 degrees BTDC.
Running on muffs I adjusted it to 6. It ran worse-lots of vibration and just didn't feel right-hesitation when I gave it throttle. Went to 8, much improved. 9-10 very nice idle, very smooth. Revved it up in gear and out seems to be okay.
Is this an indication of something out of wack?
Does this have anything to do with the fact the engine was made in 1976, never rebuilt, low hours-650, and the leaded fuel was different back then?
Any help is appreciated. I have not been able to water test this after the timing adjustment.
Jim
