Once they are set up, they work great. My car always starts, gets good gas milage, and they sound cool also. Mine were set up WAY too rich and might have killed my rings, but it seems to have quit burning oil (since Shasta). Every car with solexs that I have ridden in has had good drivability around town. If you find a solex roadster you shouldn't be disappointed.

Most everyone wants the solex or sloex-like setup.

I have never driven one (I tried to find ya Will at shasta but I couldn't find ya), so I can't go from experience.

On the web I read that the solexs have hesitation on stop and go from idle. This logical to assume since solex are meant for racing and in racin gyou seldom do a lot of stop and go. However, this rumor stems for the lack of owners not knowing how to adjust those babies for street use.

Another logical assumption is that you will see yourself adjusting the solex a little more or not to too noticebly more. SU are bitch to adjust becuase the compounding adjustment, but stay pretty set after being set. The Solex are adjustable as often as Webers. Ask some Weber carb owners to get details on frequency.

Full consumption is more of factor by use and performance. Higher performance and heavy driving. An SU consumption can be very close to Solex consumption when driven very lightly. At idle they should almst identical. On acceleration the Solex should be higher.

A Solex can induct more air than an SU for getting of added power from the same combustion chamber. If fuel to air ratio is the same, then yes the Solex will use more fuel.

I prefer the power. My Roadster's primary purpose will be for personal mental therapy. Fuel consumption is secondary.

I haven't noticed any hesitation with my setup, infact throttle response is almost instant. The only drivability issue that I have found is my flywheel. It is the stall monster, due to its lack of inertia. Its just kind of a pain. Nothing big, just a little irritating sometimes.

DISCLAIMER: My solex powered beast is not yet a driver, and I have not worked on Webers.

That having been said, it is generally stated that Mikuni-Solex carbs are "set and forget" carbs. Dellortos have the same reputation. Webers have transition porting (I am told) that is not as good as the other two, and that may lead to some of the finickyness of their adjustment. Most folks that have Solex cars seem happy....

I'm with Will - anyone who has drivability problems with solex's doesn't have them set up right - It ain't hard to set them up either. I used SU's on my car for 18 years and liked them a lot but once I put the solexs on, I wanted to kick myself for not doing it years earlier. I'm running the 37mm chokes too and have no issues with hesitation or low end torque. The SU's work well IF the carbs are in good condition. I'm not sure I would spend the money on Solex's if I were using the car as a daily driver or cruiser but for any really spirited use, I highly recomend them.
