I'm in Manitoba Canada at about the 50th parallel, at ~930ft elevation, and the hottest days of summer here, rarely get past the mid-90s, but most days in July, are in the mid- Eighties.
>My engine has been running just fine on 87E10, since 1999.
Ok sure, after a week of sitting, the leaky front pump has partially drained the front bowl. Sometimes I prefil the front bowl, and Sometimes I get lazy and just stomp the double-pumper a couple of times.
>After she's warm, on any restart, she'll usually fire up on the first revolution, often on the first or second cylinder that comes up.
Well, to be honest,
>I have a couple of secret weapons, namely; 180psi plus CCP, a 750DP on an AirGap, fresh cool air from above the hood, a well-synced transfer slot, and a shady North-side carport, that stays relatively cool.
>The thing is this; fresh 87E10 begs to lite off. At 80*F, the VOCS are anxious for a spark. After a week in a vented fuel tank..... not so much..... unless it's been "stabil"-ized, lol.
I've been running that cheap skunk-pee since 1999, and everything on my yard has been tuned to run on it, cuz it's the only gas sold in my town.
>Op is in Florida; what's the elevation there?, and how hot does it get ?
Wiki says the highest point is 345ft and and the summer temps are maybe a tad higher there as here, namely upper 80s. Thus my engine would be right at home in Florida.
I understand that some of you guys have trouble with percolation down there; I get it.
And I get that the gas companies have reformulated their fuels for EFI closed systems, which can create starting issues for carbed engines; I get that too.
What I don't get, is your aversion towards alcoholized gas, when it clearly is a winning recipe, when you work within it's limits. Sooner or later it's gonna be all you can get, so you might as well tune for it now.
