Re: 1956 Oliver 5.5 hp won’t start

Frank, I know that the new o-ring and old are very close in diameter
as I looked at both today. When the carb is tightened, and o-ring
compressed, the reed flange to power head gap is 1-1/2 mm or less.
When not compressed, the gap was 3 mm. I really don’t think one
could have an o-ring in there and have the gap any less.
I will take the cowls off the Chris Craft tomorrow and compare,
and switch carbs if all else fails.
I have brand new "Outboard Jim’s" Scintilla coils and condensers.
Spark sure looked good at the plugs, but I did not try an air-gap
spark test. Not sure what’s air gap jump is normal for this type
magneto, are you?
Hopefully I’ll have better news tomorrow!
Thanks
