OK, what's the deal with Webers?
Seems like everybody is talking about them, looking for them, and asking questions about how to fix them. I am guessing there is something people like better about them than the Aisins? Should I be EBaying my factory and backup carb?

For me it was laziness. I got tired of dicking around with a 26 year old carb. You can barely find new parts for the Aisin carbs. The Webers are the only carbs that are basically a bolt on affair with minimal fabrication. I would still be running the Aisin, but I could never get it to run decently... The Weber is definitely not perfect, but it runs better than my OEM one. I still have 2 spare OEM ones I am keeping just in case, but I doubt I will be using them.

With that being said it is true about the 36 year old carb. It will always give you issues but if you want to stay OEM then just go for the vacume delete and then take some parts off and make it a preogressive carb and then it will be almost like a weber. But The 32/36 carb is a good carb but there is still room for improvement. Meaning jetting and setting it up. But if your going to buy a brand new carb from Ebay or redline then to be honest the amount of money your going to spend...you might as well jump on the bike carb install buddy. Cause thats the way im gonna go my .2 cents.

I am talking about the physical age of the carb, not the age of the design... Razz Every Aisin carb I have had has been pretty used and abused, and I have gone through about 4 of them. Replacement parts are not easy to source. Like I said... overall, I did it out of laziness Very Happy. Though I am really thinking about bike carbs on my next build... Or I may just get lazy and go 4ag, though that means I need to work a shit ton of over time. Razz 4ac stuff is pretty cheap though in comparison, so probably 4ac it will be.

My 32/36 was a compromise between my cars original Aisin and my twin DCOE's. I didn't like the aisin much, yet at the same time I didn't want to deal with re-tuning my DCOE's every time I went to the store for groceries.

Originally I wanted a single DCOE with a lynx manifold... Then I saw how much they cost! So I went with the 32/36.. Smile

i think that the 32/36 carbies are great for street driven cars. They are reliable, for the most part stay in tune once you dial them in, and your car gets more usable HP/better MPG to boot.

Yea I always draw out a cons nad pros list most of the time and well sometimes i just say screw it and just buy stuff andtry to make it work. But the 32/36 is a good carb dont get me wrong i mean its prety much cheap if you can find it second hand. But if your going to spend the MSRP on a weber thats 300.00 + new rubber fuel line + FPR (for those that want it) + mounting plate (if yours didnt come with it. I say thats pretty much a over kill on price. If I would of known about the bike carb route then I would of saved my money and went that route. But if you can get a weber carb then I say jump on it cause its sure is a upgrade from the stock carbie. Im not dissing the weber its just...there are other options out there. Modding your orignal carb , bike carbs and well I guess just the good ol 32/36.

Probably because Webers are everywhere; they're still being made and adaption parts(linkages, brackets, etc) are cheap and easy to find. It also probably has something to do with the knock-off market, or should I say the not-so knock-off market. You have to pay attention when you buy a Weber carb to make sure it's really a legit European-made Weber and not a Chinese-made look-alike that has been branded a Weber.

Read this if you're in the market for one:

Aisin carbs after 20+ years of hard use end up wearing out at the throttle rod, it can be sleeved, but that's just as costly as just throwing a weber on it. I'm now to the point with my Aisin carb that I can't get a consistent idle, and even when tuning the carb I can't get a smooth idle due to the vacuum leak. As mentioned before, Parts are pretty much impossible to come by and a new one is way out there on price. I love my Aisin carb, but I'm going weber due to cost, and it's the easiest way to fix the problems I'm running into with fuel delivery.

Hey thanks for the input. I'm asking because I've been having a rough go with my stock Aisan. I've had it open several times since summer, accelerator works great, above-idle works great, passes all the vacuum diagnostics, but it just won't start (well, it push starts great) and occasionally stalls during low idle. In its behalf, pretty much every piece of rubber in it was toast and yet it still ran almost as good as after replacing them.
I'm interested in the comment about the throttle pivot. That could definitely explain the trouble. I don't feel any play, how much are we talking?

Throttle shaft wear is a common problem with many carbs, not just Aisin carbs. It doesnt take much wear to let enough air in to cause problems.
The way I would test it would be to spray the end of the throttle shaft with carb cleaner while it is running/ fully warmed up. If the idle stumbles or it dies, then you have a leak. However you might have trouble with accessing the shaft end without spraying a bunch of other potiential leak areas. so be mindful. However I would be suprised if your hard starting is because of a worn throttle shaft...
Check to see if your choke is closing when the engine is cold. I know that that can be an issue. There might be a computer controlled 'cold start' valve of some sort on these that may be an issue as well.
