Post your Mikuni carb pics.
 

I am installing my Mikuni, post pics of your installed carb please, advice also on what to do with the two outlet/inlets on the underneath of the carb.

Steve

i dont actuallt own the car yet :D but will this saturday :jump: sorry i have no helpful info, but it is a pic of a 44mm mikuni

what are your plans for the carb? what kind of build are you doing? what kind of hp you aiming for?

wow, that carb looks pretty serious! What applications would you use this carb for? Mainly for getting the most hp out of the car? And how much does one cost? Also mech secondaries or vaccum operated?

Ryan

^................. are you serious?

its a 2 barrel. there are no secondaries.

sounds like dude needs a 2 barrel for real.

a 2 barrel bong :D

Mikuni is excellent for stock or mild stree port, not for max hp in a wildly ported engine, but can easily make a stock 12a release 150hp with decent exhaust and ignition. This is my DD with full interior its the conservative nice car, my 83 however, well, I'll reveal that later on.

This what you're referring to?

ooo, I wouldn't mind one of those carbs. How much are they going for now days?

Perfect, thank you....

i'd say a setup including intake $350-$550 depending on condition.

coolant to the carb?!?

sorry guys, just got the car, don't know to much about carbs but Iam learning

I have 2 of those carbs and did not know those 2 extra nipples, that I have capped, were coolant lines. Most interesting.

Steve, I hope I didn't steer you wrong in my PM.

Here's mine.........I don't have the 2 extra nipples capped. Didn't know they were for coolant either. Learn something new everyday.

Mine has the 2 OMP connections plugged but has the coolant nipples? So do I need to remove the OMP and go pre mix. Where do most of you plug into coolant from. Or is this backwards.

Hey Scott, no problems, just trying to work this thing out, have it mounted, fuel lines run, just working on the throttle linkage and whatever those two nipples are supposed to do...

What the hell do I do with this throttle linkage?

What did that carb come off of? That is nothing like the linkage setup I have. I'll post pics later tonight of the spare.

Hope this helps give you an idea of the brackets needed. I don't really want to part this carb out, it was set up for an SE and I have the UIM for it too.

You might try contacting Wolf Creek Racing, they are the east coast supplier fo Mikuni. There is one on the west coast too, but I don't remember who they are.

Your other pics will be in the mail soon.

In the top pic, the bracket at the top of the spring holds the cable sheath, one jamb nut goes on each side like oem. The cable then wraps around the curved lever arm, lays in the square block at the bottom, it's held in place there by a screw and the round end of the cable goes in the very bottom hole.

The lower pic shows the top of the carb and the starter lever and bracket where the choke cable goes. Th Mikuni's don't have a choke, per se, it's called a starter circuit and richens the mixture instead of reducing the air flow with a choke butterfly.

You can order a manual from Wolf Creek that covers most of the operation and tuning of the carb. You will get a loose leaf copy of the original. PM me if you want a copy of a copy.

Does your carb have the lever arm on the other side of the throttle shaft for the mop rod? When I bought mine on eBay, the mop rod didn't come with it. The 1st gen rods are too short. I ended up modifying a 2nd gen one to fit, then had to drill the pivot on the mop lever to accept the larger diameter 2nd gen rod.

Mine has a complex arrangement on the other side also, I will contact wolfcreek.

Update, apparently I have a race linkage which allows for throttle cable adjustment to get better response for track days, cool huh, I also found the cable link, it was attached to the top of the carb, i just didn't recognise it as it was out of place (for security)

See the brass screw to the upper right, that's the linkage.

Post pics, you can't get away with a statment like that and not do show and tell. LOL.

Hehehe, I was taking the photo and loading it, I knew better than to leave you hanging.

What do you do about bumping the idle for AC with this carb? Or any of the aftermarket ones?

personally I remove A/C, its a sports car, IMHO

Set the idle up in the summer, turn it down in the winter.

Wanna be webers...




bump 4 good thread.

So Hyper, which came first, the chicken or the egg, errr the Mikuni or Weber. I detect a note of disdain for the Mikunis in your bump..

Only reason I would go with a Mikuni before a weber is because of the OMP lines built in. I am lazy and don't want to start pre-mixing. They also work well on a stock port engine.

The weber will make more power though. . .

Did you see a desent HP increase with just the carb and not the exaust?

(looks like the stock header on there)


To everone:

Wouldn't it make better power if you curved out that intake manifold a bit more. Those sharp angled bends have to be cutting your intake velocity down a good bit.

Run that shit without the venturies and you will notice a difference.

with a little imagination the webbers can accomodate OMP lines. you just have to built it in yourself w/ little brains

wackyracer's RX-4 w/ my previous mazdatrix custom 4port 13b w/ modded 48 IDA w/ OMP lines built in-house. and when i say built in-house, i mean the garage. ask wacky :)

Someone, please slap DoLuck. He is having wet-dreams again. :rlaugh:

are mikuni jets different than the weber and dell jets?

haha I am in FL its hot as ass here AC stays. Nahh tried that I bumped it up to 1.2k and it was unreliably steady with AC in the city. It would stall coming down from higher revs for a red light. Works fine on my turbo FC's. So I went back to one solenoid and throttle opener, took some tuning though.

Now you're asking for it. :D

Really though the factory throttle opener canister and solenoid could be adapted to any carb, if you really wanted.

Or you could shut the A/C off when you're sitting there idling. :)


I found that stripping the interior out makes it approximately 400 degrees hotter in the car in the summer, basically a car becomes a toaster oven. I can't handle that kind of heat anymore. If i stripped the interior out of one of my cars, I'd adapt some A/C for sure. (I say "adapt" because the OEM type stuff has got to be horrendously expensive by now)


Steve, glad to see you got the carb mounted up!

lol @ peejay.

Yea I was just asking what people were doing for it with this carb.

Is that bagel oven or pop tart oven?

Come on Ray, if your going to push Weber's please at least spell it right!!!!! :)

they are different. unlike the weber and dels, mikuni's main jets are screw-in type instead of push-in.

lol

know of a good source on them?

The picture was taken right before I put the Racing Beat on. Night and day difference from stock.
