if its not adjusted right, it takes longer to produce a spark and the timing of the spark dosent agree with the rest of the engine so it dosent fire right

so bigger gap = retards timing and smaller gap = advance?

interesting

To a small degree, yes.

from the horses mouth (briggs website):
Quote:
ĽAn armature air gap that is too wide will prevent spark. Not true. Well, sort of not true. Briggs & Stratton air gaps cannot be made too wide to prevent spark providing the coil is healthy and the engine is spun over fast enough. A wide air gap, say .030" will ever so slightly retard the ignition timing as the magnetic field takes longer to build within the coil windings
so probably not the issue here.

i wonder did you set the cam timing correctly? maybe its a little out (i assume you had it apart when you were playing with the oil slinger etc)


Was it doing this when fitted to the mower? if so then could be valves need work/adjusting as mentioned earlier.

you cant pull the motor so fast due to it having no counter balance and a light flywheel, "A wide air gap, say .030" will ever so slightly retard the ignition timing as the magnetic field takes longer to build within the coil windings" even ever so slightly is going to be messing around with it more due to its now sideways than vertical

My point is...make sure that everything is within factory spec.
What carb are you using?

That air cleaner is not helping. Very restrictive. Like having the choke on. Take it off and try.
