Attempting the Weber carb install

[zoe60]

Also with the Weber adapter for a Suzuki Samarai, You get the flathead allen screws that fit the Festiva carb stud holes. and the 4 allens that hold the two pieces together. If you made them for people you would have to provide those. Weber adapter plates are around $42.00.

All I did was trace the bottom of a spare Festiva carburetor on paper. Then when you trace it onto your aluminum you have to make it as wide as the Weber top plate. The big holes are 5/16" and countersunk with a 5/8" countersink. Then you just drill and tap the 4 smaller holes after tracing them off of the Weber supplied top plate. The Weber part already had 4 allen screws with recessed holes so the heads are flush. That was the good thing about the kit. It had the adapter plate with it. I just remade the bottom and tossed the original part. Sorry I didn't measure anything. It is completely improvised from scratch. That's just the way I roll! I'd be proud if others made them, It's actually Webers design.

Hmmmm very simple and effective design. Would you be able to lend it to me? Or really, all I need are tracings of the flanges and bolt centers... more points if you have the CAD drawings of each Would be pretty easy to cast and machining wouln't be killer either.

[zoe60]

Sorry- for anyone that hasn't seen a Weber adapter plate, the top part with the studs came with the Redline kit along with a bottom part that won't fit a Festiva. I just made the bottom part.

[zoe60]

This is the bottom part of the adapter plate that I made. At this point I still needed to counter-sink the holes on the corner.


Here's all the parts before I put them together.


Ok, here's the whole thing assembled and ready for the carb.


Aha! Here's the entire assembly!


And heres the whole thing installed on the car! I think it looks like it was made for it. Whadaya think? Oh, I forgot to mention, I do have a bench grinder too.

Everyone's gotta start somewhere, with what they have on hand and what tools they have available to them. Casting is just one way of making parts, it's my forte' so to speak. Do you have pics of your adapter? I'd like to see it.

zoe60, Don't feel anything but proud. There were, and still are some pretty amazing things done just the way you did it.

Remember the movie, The Worlds Fastest Indian.

[zoe60]

I feel kind of silly. I made mine out of 3/8 aluminum using a hacksaw, a drill and a file! What a PITA! Worked out real nice though. That is some beautiful work. Wish I could do stuff like that!

drool drool drool Oh my gosh!!! How frickin' SWEET!! Those are awesome looking!! Great work,man!
Almost makes me want to change out the solid BILLET adaptor I made. :p

I think your about to be inundated with requests.....

That would have been helpful a couple weeks ago. However to answer your question, it seems this is becoming a trend. I am not sure how long it has been going on, but its just easier to replace the stock carb with a webber to eliminate most of the vaccum lines.

Well I dont know how much help I would have been, my foundry products usually move pretty slow, but I'm thinking for the future

Do you have some kind of patternmaking equipment? I think that those with 88 or 89 Festivas are due for a carb rebuild. Unfortunately, the factory carb is all choked up and not worth rebuilding.

I doubt anyone with fuel injection (89-93) will want to convert to a carb, because they would need the carb, manifold and a bypass pressure regulator.

I have a mini shop at home I can use to make my own patterns. I worked in an iron foundry for ~3yrs, been to numerous other ones, and I've been hobbycasting for about 8 years now. I'll post some pics of my work below. At this point approaching winter it makes casting tough, but in spring I can get back in the swing of things

if you could make an adapter to fit a Nikki 4bbl carb from an RX-7 (FB) i would kiss you!

no, wait, if you made a long tube, highrise manifold for the aforementioned nikki, THEN i would kiss you.

If you have the $$$

Here's a couple things I've done:

Tbird turbo inlet adapters


B6T intake pipes


Model train parts (2 trucks there, still on gating/tree)


Like I said, its a little tough for me to make parts at the moment but a carb adapter should be simple enough, if there is a demand then maybe we can work out a group buy or something.

Sorry for the threadjack...

Kind of off topic, but are there a lot of people converting carbs? I have some casting capabilities, and could potentially produce adapters or even whole manifolds for different carbs if there is a decent demand.

.
It also means you need to have a good DMM, or be able to borrow one.
I'd give it a shot, better if someone who has an operating unit could provide the data off their setup to help Brickdog get his tunned in!

I am not going to say how I got it, but I got a pretty good digital fluke multi-meter.
