Old thread revisited. I have a 1996 40hp that Im beginning to suspect has the worn cylinders but high compression numbers.
It will start but seems to be a Dr Jeckle personality. Plenty of power from 1/2 throttle up, but will fade out much below that consistently regardless of engine temp and when restarted seem to run like it’s too rich (shake/unsteady idle – NO SNEEZING OR LEAN RUNNING characteristic) and not be able to get up in RPM’s. It will not idle down to below 1,000 RPM without fading out. You can catch it by re-priming to stop the stall.
Shows 130/130 for compression, good spark. Ive already rebuilt the carbs and did a link N sync.
Does this sound like a familiar scenario to anyone?
Dan you mentioned early in this thread that you can switch back to the earlier metal carbs; this has the plastic top ones. Im guessing the pre-89 fixed jet metalcarbs would NOT work on a later model motor?
