Hahahahaha....
I know some people run 100LL full time in a variety of engines but I'm not a proponent of doing that. Lastly, here in California, we absolutely Cannot find Ethanol Free fuel anywhere. Pretty sad so many people are forced to deal with and pay for some of the worst fuel in our Nation...
I hear you, at the time I thought I stumbled upon a free supply of as much 100LL as I wanted! it was fun for a few months and then all my toys started crapping out and I knew what the culprit was right away.

I don't know what the hell is going on out there in California, I love the place but dam that sucks you can't find any ethanol free gas anywhere. I went to flight school out in San Diego and used to race Glen Helen from time to time.

Im back home in New York, and im sure that'll be the case here too. Might be Time to move.

If pulling the pump, what do you do with the air pipe hole next to spark plug? Cut the pipe and put a cap on it?

I'm awaiting parts and sitting here looking at that pump. I've already got a manual petcock, why do I need this nasty thing? Soot at every hose connection.

Sounds like a lawnmower, Rides like a paint shaker!

I got 99 problems but fuel injection, 6th gear or a 2nd cylinder ain't 1!

IT is not a pump. It is simply a vacuum controlled Valve.

One can cut a steel plate, drill a bolt hole, use a dab of RTV on the o-ring and bolt the plate down. Then cap the vacuum nipple IF using oem fuel tap.

Or purchase an EM AIS block-off kit. https://www.eaglemike.com/Air-inject...ff-kit-AIS.htm

The nipple on the downstream side of carburetor is actually a branch. One branch connects to the AIS while the other branch connects to the vacuum operated petcock. So if you have eliminated the AIS and installed a manual petcock, you will need to cap both branches. I used a garden-variety rubber cap to cap mine and noticed after a year or so that each cap had multiple longitudinal cracks, which would result in imminent failure. Since these caps are not easily visible, I decided to pull the carburetor and permanently seal each branch with a dab of rosin core solder.

Good idea. I was looking at the cap for the petcock last night and it's starting to show age even at less than a year old. It takes so much heat where it's at.

Thanks!
