the flame thrower advertises that you can enlarge the plug gap to get better gas and more power but it doesn't give a suggested plug gap? anyone have any experiences with this? Thanks
My 51A with 7.45:1 compression, Champion 16 plugs .035 gap & 50A with 10.5:1 compression, NGK 5724-8 plugs .035 gap, no problems so far. Either one will usually start by the 2nd revolution.(quoted from post at 06:17:00 07/17/15) the flame thrower advertises that you can enlarge the plug gap to get better gas and more power but it doesn't give a suggested plug gap? anyone have any experiences with this?

(quoted from post at 17:17:56 07/17/15) Nothing wrong with the gap you have. I keep reading wider and hotter is better but there is never an explanation of how it helps anything. The only thing the plug does is ignite the fuel/air mixture.
The gap changes nothing. There would be no difference in stating a stick of dynamite will have more power if you double the cap size. That cap is just like a spark plug, it ignites and nothing else. If a bigger spark is all it takes to make a bigger boom when no other variables are changed someone needs to explain how it's possible. JMO

Fun chat! I thought it was interesting that D reported longer time elapsed between plug fouling with a wider gap. I wonder if the wider gap leads to cooler plug arc points?
Bob's comment on a poor combustion mixture sounds valid. A wider gap as a Band Aid for an improper fuel mixture? Our old friend Glen would like that. LOL
