The motor in question is my 1962 5.5hp Evinrude. I have recently taken it apart to get it running correctly.
I now have everything back toogether. The motor runs really well from just past "start" on the throttle to WOT. The problem I have is that it wont start unless the throttle is almost fully advanced, and if I throttle down to near the "start" position it will begin to hiccup and die. It sounds to me more like a miss than a cough. It doesnt seem like much I do to the low speed needle will affect this.
My troubleshooting leads me to believe this is an issue of bad coils. I think that my spark is probably weak, and wonder if it is intermitant enough at idle that it would cause it to be so rough and not to want to run that low. I reseated the coils because they were draging on the flywheel, but I didnt replace them.
It looks to me now that I look harder that the top coil in the picture is beginning to crack, the bottom is difficult to determine in the pics.
Does it sound like I am on the right track?
- I rebuilt the Carberator with a kit, and replaced the float.
- Fuel filter bowl assembly throughly cleaned.
- I removed the powerhead and replaced the exhaust gasket.
- I installed a new waterpump and thermostat.
- I blew compressed air through all fuel (carb) and water passages.
- I regapped and cleaned the points.
- Head Cover was removed, gasket replaced
- Spark plugs are brand new.
- High and Low speed Needles were adjusted per the Joe Reeves method.
