Brief background (apologies for the length ):
Got this engine, used ~ 10 years ago to replace the same motor in Johnson model which was stolen. That Johnson was always a bear to start after a few days of not running. Once it started, it would start with one or two pulls as long as it was used daily. Once started it ran fine.
I replaced it with an E'rude because it was in inventory; I had heard (anecdotally) that despite being essentially identical, E'rudes always started better than Johnson. That does not seem to make any sense since the parts are the same but this E'rude was assembled in Belgium ... no idea where the Johnson was put together.
The E'rude turned out to be the same tough starter ,... especially in the fall (Canada).
This year I had some bad fuel and ended up replacing all the fuel lines and R&Ring the carb with a full kit. There is a small "foot" on a small tube in the float bowl that has a crack...is unavailable on any part source that I have found, but does not seem to be a problem at this point.
Happy end result is that this puppy now is a one-pull motor even after 10 days of not running. Looking forward to seeing how it does around the freezing mark.
I had always ascribed the hard-starting to how lean these motors are designed and setup to run. Obviously way off on that.
It just needed the carb cleaned.
That is all the back story.
The link and synch instructions are giving me fits. Guess I am old school ... my other small O/B is a 1975 6 hp. that I also have the OEM manual but do not refer to it often and have not seen a L&S section for it at all
1)Step one in my manual for the 8 HP is an exercise to define TDC using "OMC Tool XXXX". I do not have one of those. lol
I could rig up a dial indicator and get pretty much the result that I need, but :
Is it really needed? Can I have shifted the timing somehow just taking off and replacing the carb?
2) The remaining instructions are fine, but unless i am misreading/misunderstanding, the idle speed is adjusted by turning a fitting on the end of the handle. That does not seem to have much of an effect with this motor except that if adjusted too much the stop button does not work.
Any explanation on why that is?
Current status of this motor after the carb cleaning and rebuild is that it starts perfectly, and runs really well above half speed. It struggles a bit as it accelerates.
Idle is fine but stalls on occasion at slow speed in gear.
Thanks in advance for any insight.
