haha shouldnt you be working, for that matter so should i!

Jason,

Your dealing with a 30odd year old carby so things do wear out eventually.

As for the quality of the Solex Mikuni Carbs as used on the 2T-G I personally value researched opinion of a factory racing division over the narrow minded opinion of any one person.

TRD actually recommend the Solex Mikuni Carb over ANY other side draft but hey I guess they wouldn't know

Here is a scan from the TRD Catelogue:



Please note TRD sell BOTH webers and Mikuni's !

Sure they are an OLD carby, poor condition shouldn't be confussed with poor quality. If it wasn't for peoples lack of ability and knowledge on how to actually tune a carby correctly, Mukini's wouldn't have such a bad name. Its really starting to shit me how poor quality workers blame the product rather than admit they don't know what they are doing and yes this is a pet hate of mine

Its my lunch time sanity break

Hey Like I've said I have no Problems with the Carbies if i did I'd swap them for something different. Just that I was not aware of the problem related to the ventruies and just try to warn people to check them. If i knew before i wouldn't have the car in the garage at the moment not running.

One thing i have learnt is i'll be checking them offten now.

As I've found out these parts are hard to find. And unfortunatly now one around here knows anything about them so I'm left to do the dirty work myself. Actually no onw up here whats to touch a Carby engine EFI only.

ill swap you ! lol trying to work on the cars and mind four kids! trying to get the dizzy set in a commodore with kids yelling"dad im hungry" bloody kids have worms!hahahaha

Bill,

Good to see your ignorance and bias hasn't changed.

Well gee, let's see.
I haven't worked on a lot of them but 100% of them had the same problem.
This guy starts a thread, and my first guess is right.

You carried on about this some time ago - You were wrong then and even more wrong now.
What part of that are you having trouble with ?

[TheToyman75]

So Bill should I do a search for "Mikuni" in the Tech and conversions section of the old forums and re-highlight who was wrong ?

Nothing like a trip down memory lane

Oh and by not allot..... I assume you mean 1 ?? The one from 1985 right ?

I'm not the one who doesn't know how to use a factory lock washer or the one claiming to know better than the race team who actually raced the engines in question.

Thanks for the laugh Bill


Mick,

4 Kids.... Dude you need to buy a playstation or something

Rod, as stated in that thread you're an idiot.
Here's why - I said quite clearly that the carbies on both engines were as they came from the factory, untouched. Nothing to do with me improving them or making them worse or whatever. That the way they came, and they were both crap. So was the one in this thread. Did you miss that bit? I got it right first time, no-one else did.

Those are facts, no matter how you try to cover your arse by altering that.

Another fact - When I was mucking around with them in the 80's, it was common for the people getting big power from them to ditch the Mikuni's and fit Webers. When I asked why they did this, Jimmy Bertam of GP Cars who built the thing said that they "immediately gained 10hp by doing that."
So to make that simple for you, by not using the Mikuni's there's more power and more reliability to be had.
Understand that?

[Celica_73]

Ok this may stir the pot a little but on my carbies there was no lock washer on any of the screws for the large, small venturi of the sleeve. The nuts were tight and required to bit of force to undo them. Even so the venturies still were loose. I'm guessing over the 30 odd years of use the matterial wore away and the losser it become the quicker the worn until it fell out.

I have to admit I really don't know much about Carbies at all so Not entering the decussion on which is better webers or solex. All I know is what I've heard and read in these forum. Which mostly comes from the you two.

From that link ->

Diagnoses over the net only works so well and you would need to have a good understanding of what is going wrong for it to be of much benefit.

Dude, seriously, just don't even bother any more.
I got it right first time. The post above this one has the guy heading the same way.
You are not able to debate the technicalities so I am going to leave it at that.

[Rodger]

All sounds very interesting.

Loose, broken or missing inner Venturis are one of the most common problems I see when rebuilding or repairing Solexes

If anyone has recently checked their Solexes and need parts. I may be able to help.

As Celica_73 has said the parts a getting rarer and rarer. I have trouble getting parts.

Although I have a few tricks up my sleeve, from mucking around with these for 20 odd years, to keep them running.

At the moment inner new venturis for the S5 Solex (2T-G) are $40 each on exchange with worn old ones.

Rebuilt and used good condition ones are $30 each on exchange.

Bill,

ohh ohh pick me pick me I remembered what somebody once told me. Your a joke !
Argueing with you is like beating up a cripple and I try not to pick on the mentally disabled.

I'm sure "Jimmy Bertam of GP Cars" has worked on heaps more 2TG's than Toyota and TRD did, Hell I recon his budget must have been 1000 times theirs !! All this shows me is he has NFI idea how to set up a Mikuni Carb and has a better idea about how to set up a webber. And of course everyone knows that peak power is what you chase in a race car, that midrange torque thing is for taxi's.

I said it before and I will say it again poor maintenance does not equal poor quality. Anyone who has seriously played around with Solex Miuni carbs knows about the Inner venturi's coming loose. But lets see the set in this thread are How old ?? And have been rebuilt/rekitted or maintained when ???

Seriously Bill go hang out on the Hot 4's forum or something where you can carry on like a 15year old with a motor magazine and still look like you have half a clue. There is an old saying. "In the land of the blind the one eye'd man is king" This isn't the land of the blind, your not the king and as usual your about as accurate as the weather !

[Billzilla]

*sigh*
An impressive diatribe, but as usual quite wrong. Anyone that knows me or my work knows that.
As people know, I have been involved in motorsport since the early 80's. I've done a lot of thing but the better stuff is -
- Run in six sports car national championships. I've never won it outright though I've been on pole position twice and at the end of each championship event have never finished worse than 3rd.Yes, the car has broken down a couple of times, eg, last year where I would have won very easily if it didn't.
- I also run every year in the international event in Malaysia called the Merdeka Millennium endurance race, which runs for twelve hours in August. Number four for me is coming up in a few months. We're a small private team against the big-budget factory-backed teams and have not secured a podium finish - yet.
- I have helped people all around the world with their cars and engines and drivetrains.
- For those getting the new Wiseco 20v forged pistons in the future, I had a small part in that happening. Ask Brian Nutter from Wiseco.

The problem with the Mikuni's failing is well documented, yet you keep ignoring it as if it doesn't exist. It's not a matter of maintenance, it's just a poor design that people shouldn't have to put up with. I've never claimed that Webers are perfect but they work better than the shitty Mikuni's that came with 2TG's.
You don't seem to realise that Mikuni's are very popular in Japan becasue they're made in Japan and Webers are not. They have been used successfully on many cars in Japan but only after a lot of work done to them. Same deal with Webers - But we weren't talking about modified carbies, we were talking about standard road ones and as witnessed several times in this thread and the one you linked to, people have the same problem over and over again with them. Webers will run for many years with pretty much zero maintenance.
I gave an example of people working on 2TG's back in the 80's because they were winning with them. Nobody used the Mukini's.
You can try and hand-wave and waffle on all you like Rod, but you are wrong.

[Joshstix]

Mikuni or Webber it doesn't really matter, they're both antiquated technology that has no real place on a road car in this day and age. Any old mechanical device that is subject to the vibrations that carbies are WILL fail over time if they are not correctly maintained. I have seen a lot more problem webbers in my time than Mikuni's but thats most likely got more to do with the relative number of each kind of carby I have seen in use.

The original posters question has been answerred so this one is getting closed.
