I am going nuts trying to figure why this 1975 merc 500 with lighting energizer ignition won't open up past 3200 rpms. I have gone thru the carbs, they are clean & set perfect. Have inspected distributor, and replaced driver coils, have replaced ignition coil (all new parts), set timing low&high, checked resistance of all dist.wiring, Tested on the water, will accelerate to 3200 then slight steady miss, squirted premix into both carbs, boggs down, all plugs are slightly oily/wet when pulled, Any ideas anyone? also compression is great.
