Re: It just doesn't run right-200 Merc
sounds like the low speed windings in the stator are going out,
Maco, did you get yours fixed also?

Re: It just doesn't run right-200 Merc
Troller - Glad to see you mostly fixed up there!! It's a great feeling when you yank that advance and your motor roars over 6K. You never knew all that power was hiding behind that little box. Dump that oil injection too and premix before it screws you over.

Re: It just doesn't run right-200 Merc
If it's not the coil or the stator . . . .the idle problem could be your reeds. If you've got the typical older Merc sneeze . . . try adjusting the tilt and make sure the motor is level (or at least tilted down). My motor idles real rough when it's cold.
What model carbs are you running?

Re: It just doesn't run right-200 Merc
:-/ It kinda idles OK but seems weak on one cyl. Just when it gets under load around 900 to 1000, you can feel that steady spot up to about 2000 when it clears out. Trolling at about 6 to 7 mph takes about 1200rpm and you really feel it. The carbs are the W28's and I know about the larger jets on 2 and 5 but I also am up .002 on 1 and 6 because they have been bored and sleeved and the shop recommended I go larger on those because "they run hotter". The roughest spot is around 1500 to 2000 when it starts thinking about getting on a plane. I have a new spare coil. I just am having trouble locating which cyl is weak.

Re: It just doesn't run right-200 Merc
Something I have done when searching for a skipping cylinder is to disconnect the spark plug wires one by one. *When you unplug good cylinders, the skip will be much worse, when you unplug the bad one, there will be little or no change. *
I reccomend turning off the engine between each test so you dont get zapped. And dont run it too long or you will gum up your good cylinders. The other way I have used is simply pulling the spark plugs after running the engine, the bad cylinder should be drenched in gas/oil, as long as your issue is not a fuel issue. Hope this hasn't been covered already, I didnt read the whole thread.

Re: It just doesn't run right-200 Merc
I have owned two mercury ob's, wish I had them both still, they are great motors. One was a 1984 115 hp, the other a 1987 45hp. You could look at the key and they would start.

Re: It just doesn't run right-200 Merc
I've never owned a merc, but always heard they start easy.
