I have made the acquaintance of a guy who has been mentioned here more than a few times. Keith Franck knows an amazing amount of information about the Weber side-draft DCOE carbs, and has invented and manufactured a number of innovations. Just last weekend, he had a 'tuning day' for Lotus owners who's cars use Weber side-draft carbs. He offered to include us Datsun peeps but it was really too late to set this up.

I am wondering if we have enough people who would attend a Tuning Day for us Datsun guys with Webers?

I have a friend with a restoration shop who would be willing to host in Sonoma CA... (Keith lives in the Martinez area).

We could have a BBQ and maybe even a drive, the roads through Napa and Sonoma are amazing!

Sound off if you're interested...

Coming up fast! See you there!

Bump for tomorrow? How many people do we have going?

It's going to be pretty intimate... Even Bill may not make it. He blew another head gasket at Thunderhill on Friday... Moral of this story? Don't let Bill drive your car! 8O

Bills not coming? Leon! Are you still in?

Heck yeah I'm still in!

About to print directions actually.

guys have a great day, take lots of pictures and notes!!!

I would like to thank Rob (conedodger) for the great day out in Sonoma! It was a great chance to meet a few knowledgeable Z folks, as well as a true side-draft carburetor guru, Keith Franck. Also, special thanks to Original Customs Restoration for hosting. Great group of guys.

I, being the least knowledgeable there, enjoyed learning a whole lot about Webers/Mikunis and the physics behind them! Highlight of the day was definitely Keith supplying the goods to help make Rob and Leon's cars run a whole lot smoother and quicker off the line.

Will add more photos shortly.

What a great day! Glen, Patricia, Leon, Mark, Bill, Tim, myself and our carb expert Keith. My car ran good but now it is so much more responsive and crisp. The A:F ratio is in the 13:1 range at 70mph cruise. So very much better!

If you have Webers I highly recommend Keith's Hypojets! If you have Mikunis don't fret, Bill offered to drop one of his off so Keith can develop Hypojets for them! And why not? Bill doesn't need his Mikunis! He goes through head gaskets as often as I do oil changes. 8O

I'm sorry I missed this.. I will be watching for the Mikuni Hypojets.. Please keep us posted!

Man, what an awesome day! Throttle response has never been so crisp before and the idle is so much cleaner. I love how my mixture got steadier too.

This is just the beginning, I'll be playing with the hypojets to find the optimal ones as well as increasing my pump shot and possibly upsizing the chokes. Achieving Weber nirvana is a (big) step closer! Big thanks to Rob for setting this up, Keith for the time, parts and knowledge, Original Customs for hosting, and Glenn, Patricia and Bill for coming. It was a blast!

Thanks for coming Leon. I will be switching to your ignition system as soon as you PM me with parts list and a starting timing map! 8P I can't wait!

Rainman, Keith is already commenting on Sidedraft-Central about getting ahold of some Mikunis from Bill and 3D mapping and designing solutions for them. I have mixed feelings on this as Bill is already too fast to catch. Not sure I want his car running better... :disappoin
