Reply To: sprk plugs

[Geer Pyron]

Been at it again since 7am.
Couldn’t sleep for thinking.
Gotta make this quick. Gotta work for some $.
Took it apart again. Noticed a few less than tight (snug, but not tight) nuts. Oil leaking from cylinder/crank gasket. Put it back together sans lower bronze. Re gapped plugs to .025. They were .030 plus!
Made sure all nits were tight tight.
Reminded myself that 5 o’clock is not 6 o’clock (spark advance).
Fired on first pull!!
So I reinstalled the bronze part, lower unit, and it ran. Dry.
Turned it around so it was in the water and it ran again.
Made a mess with oily water going every where.
So what was it?
Un- regulated air, less than tight tight fasteners?
Or the spark plug gap?
Or something else I did unbeknownst to my simple self?
Thanks for all the input!
It helped.
