Oh, and I’ll probably have to affix an expended whip antenna with a flag on top as none of the cars around here seem to see me. Is this a common problem?

tire pressures before I hit the highway. Any guidance here would be appreciated.

I agree, tire pressures should be VERY low compared to other cars. I've heard of other Locosters who run as little as 12-14 psi.

Bear in mind that running 30 psi in a Locost is like running 60-70 psi in a Miata's tires! Squirrely doesn't even come close to describing it! I run my '00 Miata's tires at 24 psi, about as high a pressure as I dare. I did try it at 32 psi once, just for laughs - punched it in 2nd gear (dry, flat, warm, empty parking lot) & spun it instantly. Fun...but terrifying for a street car.

As far as the Webers are concerned, that off-idle stumble is usually dealt with by richening the idle circuit. Guys with Zetec engines have been struggling with that issue for years, and most have ended up richening the idle circuit until the car's blubbering & smoking, just to get it to run. Weber, in concert with Webcon in the UK, has now come out with brand-new, modified 45DCOE's with 5 progression holes which, apparently, cures the problem once and for all. After reading about all the attempts to fix the problem otherwise, over a span of years & with zero success, I caved & bought a set of the new Webers from Webcon. I haven't done engine start yet, but I'm pretty hopeful that the 45's will be very close to right, right out of the boxes.

1st, make sure that you don't have any loose nuts/bolts in the suspension and steering areas. Ensure the lugnuts are all tight. Then check the suspension point welds. (Hempy anyone?) Then do a rough alignment. It doesn't have to be perfect. An eyeball alignment should be good enough to get started.

As for tire pressure, I ran 18.0 PSI all around. FYI, I had 205/50R15 Azenis in a 1400# car.

Since I know where you are, I'd say yes. However, you could be driving a London Double Decker, and you'd still have the same problem. I wouldn't venture south of Whistler, unless I'm driving our minivan. Unfortunately it is a sign of the times. And I have the deepest respect for anybody who drives one of our cars in the Lower Mainland.
As to giving rides, that's where it all comes together. Lot's of smiles. Even my teenage daughters still think it's cool to go for a ride.

It's a regular Gong-Show down here in Richmond. How some of these folks get a driver’s license boggles the mind. I swear, at times it feels like they're blinded by their windshield.

Last week I was visiting friends that live in Mariner's Village near your place. I believe that many of the people on the road in Richmond did NOT qualify for their driver's license, they had someone else take the test for them. There's no way a large portion of them could even take the test as language proficiency would stop them.
