Surfriding Pure 87 Octane Question

[Patrick Star]

I run a maniac engine in my B1. Its a surf boat so its all pretty much low end only at 185PSI or PE-PSI. I hate E10. The stuff funks up everything and will not store for crap. Star tron helps some. Anyway at what PSI would I have to drop to so I can run the available pure E Free 87?

From previous threads I have seen on this, its not all about the cranking compression psi. I cant find the other thread on this, but this is a link to some info.

Thanks for the links. Seems it is a in depth topic that I will have to dig into.

I can get pure 87 and not have to deal with E10.
Looks like I will have to remove the carbs for a disassembly and cleaning after every ride until I can find some pure fuel. With E10 it is just a mater of time IMO before the gunk starts, even with treatment.

I took my carbs off and they were clean, but I run an extra inline filter and a water separator and they were clogged with this film.

I spent 12 months one time in Diego Garcia, out in the Indian ocean and my old '93 fired up perfectly after 8 months of storage. Didn't even flush the gas, just treated with Stabil before hand, but that was pure 93 and not this rot gut stuff our skis are forced to drink these days.

I'm going to continue to run a big paper filter inline. An extra paper filter does a better job IMHO.
