OK,OK, I've been lurking and just sent an email to Phil this morning on the dripping subject. I was sooooo close to pulling the trigger on the Dynatek system as Rodney well knows, but the extra wiring and O2 sensors and extra boxes and controllers got to me at the end. I wanted the clean race-ready look of the original carbs without any extra things on the engine. I was, at the same time, shirking away from the dilemmas I was reading about tuning the Webers and all the expense of trial and error with the jet stacks and e-tubes, the mumbo-jumbo about chokes and jets and holders, transition circuits and the dripping and the popping and all the other "ills" that made their way into the CC annals.
However, reading this site almost every day, and doing lots of research on FE's with Webers, I decided I was up for a little tuning challenge. Priobe, eljaro and ENTDOC's input gave me the confidence to finally get over it and go with the Webers. I found a worldwide distributor 45 miles from my home, and they have the parts and the tech advice available so I went with the exact same setup as Stefano (eljaro) bought and it's pretty much period correct (although new parts/carbs from Spain not Italy) without using computers. I, indeed, spent about $400 in new chokes (40mm), two sets of e-tubes and two each sets of idle and main jets to get where I am. Probably not done with changing these in the long run, but I'll run with these for now.
I have had my challenges with the new carbs, and even the dripping that Phil is experiencing has abated. Totally stopped? No. But my DaVinci 950 4bbl also had a slight drip onto the throttle plates after hot shutdown. I can live with the tiny bit that is making some, but not all, of the throttle plates wet 8-10 minutes after shutdown. The spring gas formula seems to have helped over the winter gas.
My set up is still rich and smells rich in the idle circuit, but the popping has totally gone away. No stumbles and runs like a totally different car. The smell improves a bit as the car totally heats up. As Rick Lake said, the torque improvements are like nothing you can describe but you feel it in the seat of the pants when you hit the throttle. A real screamer and I drive it every weekend. I think the mileage may have dropped slightly but my baseline is too early to tell. Who the heck cares anyway, right?
Just like everything else, I'm happy I went this way and appreciate those that have the EFI's as well. This is what was meant for me. I'm an old school twiddler/fiddler and have not really made the full on jump to hi-tech computer-based systems. The Webers I can do with a Synchrometer, a timing light, my tach, a few plug reading sessions, my nose and ears.
Oh, and my 45 year old tool collection that I am thoroughly enjoying using again.
As an aside, I wonder how GreatAsp's (Eric's) Dynatek setup finally worked out for him. He indicated he too was having a little problem with the tune and said it was still not right after spending big $$ to install. I was hoping he was going to end up happy.
