Thanks Mike, I'm waiting for your bird !!!

[@johnwilson5653]

I thought I heard “fuel pump”? Do you have a fuel pump running fuel to the carb? What size pump, (fuel volume), ID of fuel line pushing the fuel? Seems like a real fast way to really flood the system. I didn’t see any fuel pumping systems at Ch-Ignitions

Did it fly or not yet?

Where did you find 100 octane? Did you just use an octane additive to 91 or 93 premium? Love the radials!

[@knockoffs]

Local gas station sells the 100 Octane well worth the $ 9.50 a gallon. I use it on all my engines, Keeps them happy. runs cooler and very low ethanol. That's what kills the carbs and bearings.

Maybe airport? Av Gas?

[@peterschryver]

Yes, I found 100LL Aviation fuel available next to the airport @$5.61/gal. Thanks for your advise!

Gorgeous engine. But the only reason to run very high octane (100) is if the manufacture recommends it, or if you're advancing the spark for performance and you're getting preignition issues. Increasing octane alone serves no other purpose.

@@icin4d ethanol is hard on small engines, so that's another reason
