Back in 2010, I had the dreaded hit a speed bump, engine dies Hatachi carb
problem. My solution was to go to the Weber Carb conversion kit. Mass of vacuum Plumbing, wiring and a ECU, all gone bye bye.

After receiving the kit, I could see during the mock up, that, yes it fits, but it has some
major air (Breathing) restrictions as is.
1st; the adaptor plate openings, were way larger than the openings in the intake manifold.
My solution, Hardware Hank'd a die grinder bit, Sharpied the new gasket outline onto the
carb base on the manifold, stuffed some small rags into the runners, had my sweetie run the shop vac as I opened it up with the electric drill. Just be careful, this aluminum is soft and disappears quickly !!
1st pix shows the end results, 2nd isn't the best, but I dug out the old spacer plate, and laid the new style gasket on top to show the size difference.

Having Issues with the Pix portion
I'll try 1 at a time

Well I could not get 2nd pix to go thru, tried 4X, must be too long a distance from up here in Area BFE Wisconsin to the server

The next air restriction;
Since I wanted to keep the original air cleaner system as it's hooked up to my external air intake (Snorkel), was to modify the Adaptor that came with the kit, and also the Plenum for the Factory air cleaner. The top adaptor that comes with the kit is just bearly above the choke plates and the opening is covering half of both venturi's.
My solution was to cut open both the adaptor and the plenum to match the choke plates on top of the carb. did this with a thin, fine tooth blade in a sabre saw on my tool bench.
There are a few mods to the Plenum, one is get rid of the vacuum bleed sensor as this is not needed anymore, and grind off the one bracket on the bottom. (See Pix)
Next I cut a gasket to seal between the two.

Uh, you are about 20 years late on that Weber tech write up.   

Then again, all the pics and write up on the old ORC board are long gone.  Circa 1996, not 2005 as listed.  2005 was when it was reposted.

Sad.  What was once the Mecca of Suzuki Offroad Information is now largely gone.

Anyways, the two piece Weber adapter is completely open in the center.  So even more material can be removed from the intake manifold inlet flange face.

Johnny Rash,
Thank You for finding this old post. Wish I had it in 2010 when I bought the kit.
But Great Minds Think Alike ! And on my own, I have figured these issues out,
and made almost the same solutions.
I have not experience the Hill Climb Stall from flooding, but my rig is not a
Rock Krawler, but I have tested its metal several times on Off Course runs.
Also being a later version, designed/kit for the 1.3 Samurai, I will look at that
Bowl vent modification, My vent is hooked up to the Charcol Can, maybe this
was made by the Progress that has been made from IMPUTE for the Off Road community.
Also the instruction sheets included of the carb rebuild kit, even have suggested
float setting for "Extreme Off Road Conditions", or carb placement for the G-Forces of circle track racing.
Also I highly recommend the fuel pressure regulator, I have eliminated the mechanical pump, gone to a low pressure electric pump set down to 2 psi with engine running.

And It's Great that there are Old School Sammy Owners like yourself, to help us
Rusty Iron Junkies, thru our Addiction, and Mentality of "I can Beat This" !!
