At this point I am ready to throw this shop off the damn pier?. I thinking my timing is way to advanced due to a local shop changing my timer base? revs at cranks to 5000 RPM?.
So a month ago my 96 rude 200 died on the lake (running fine? then simply would not crank). Brought it to a local ?marine shop? that was recommended (I am new to Raleigh NC and didn?t know the local shops) and they diagnosed bad timer base. This is the non OIS type Evinrude. So to be on the safe side I had them replace base, pack, and coil. Pick the boat up last week and headed to the lake today. She started after a second or two but immediately reved to 5000 rpm and stayed there. I thought what the hell and shut it down after 3 or 4 seconds. Cranked it again and it went to 5000 rpm? I let it run for a few seconds and then it backed down to 4500? So the quick start is technically working as I would have thought. First thought was its getting way too much gas? so maybe idled way too damn high??? Backed off the idle stopper and still cranked and idled to 5000 then back down to 4500. What the ?F???? thought maybe was primer solenoid dumping excess fuel into the manifold? so I made sure red knob was pointed down and disconnected the lead coming off the solenoid? So now primer solenoid was pretty much deactivated. Same story? cranked and reved to 5000 then down to 4500.
So my next thought is for some reason maybe the timing was wayyyyyy advanced and even with the idle bolt being backed all the way out the timing was still advanced enough to rev it so high. On this motor as I understand it in the manual (and from observation)?. When throttle is applied (by either throttle advance lever on control or the control/shifter itself once in gear)?. The mechanism advances the timing before it opens the butterflies? when throttle is backed down the butterflies start to close and timing retards.
But the timing adjust screw and lock nut still had the orange OMC ?WAX? from the factory on it. The shop hadn?t adjusted it at all. Sitting at the dock I loosened the lock nut and gave the timing adjust nut 4 good turns clockwise (retarded the timing). Cranked up and it reved to 4000?. Then after 5 secs to 3400? Better?
Killed it? 3 more turns clockwise on timing adjust? tightened down? cranked up and went to 1800 rpm? then 5 secs later down to 1000? A little high but sounded a lot better. But now every 6 or 7 seconds it gets cough and a puff of white smoke out of the exhaust?. Idles nice then a cough and puff white smoke?
Boat is going back to shop Monday but my Holiday weekend is screwed cuz of these jackwads. What do you guys think??? What could they have done to cause this? If timing adjust bolt wasn?t modified and they just installed a new timer base? what could they have screwed up to cause this?
