Hey guys,
Any advice?
I need a new or rebuilt carby. Or I can send my one away for a freshen up.
Any suggestions?
Regards
Baz
Best place to get a new or rebuilt carby to suit a 800cc??
Ask at your local auto spares supplier. Alternatively http://www.advancediaphragmoptions.com will give you a very capable contact. Mike's other business 'Dual Fuel' also does carburetor reconditioning
along with gas conversions.

So many delays to getting my MB back in order with 993cc & 5 speed transaxle... neighbor issue gone, donor shell up on rotisserie, new sheds on the way.... another project also..
Hi Baz.
Maybe. The car just won't idle. I can't put my finger on why - tried just about everything I can think of, and a few others have suggested. WIFE decided the time was ripe to take it to an expert.
Dropped the car there this evening. - The guy tells me he will call me tomorrow when it's ready... I like his confidence. Hope he's right.
He is a carburettor specialist, so assuming he get's my boy's idling issues sorted, he would be the man to take your carby to...
I'll keep you posted.

Hi Mowog.
Yes, I strongly suspect the carby is at fault here - I had it rebuilt in November last year and it ran sweetly up until the head gasket shit itself.
It's taken about 8 weeks to rebuild the engine and the guy from the Carby place also asked that very question right off the bat. So I'm hoping he'll strip it down today, find some gunk, clear it out, re-assemble it using my new(ish) gaskets and all will be sweet.
I'm just over fooling myself at this point that I know anything at all about fuel mixtures etc. and I don't have a tacho to set the idle revs properly etc. (Goddamn chinese/japanese/korean/whoever manufactured tachos only doing 4-6-8 cyls!) Try finding a workshop tachometer that does a three cylinder engine that isn't nearly worth more than the car!!!
I'm also not too impressed with the carby itself - precious little thing that it is... It better give me some good results once all this bullshit is done and dusted!
Cheers

There's only one mixture screw, and that's for idle. Screw it in until the engine starts to struggle, and back it of 1.5 turns. Running mixture is factory set by the jets and venturi.Tez wrote: I'm just over fooling myself at this point that I know anything at all about fuel mixtures etc. and I don't have a tacho to set the idle revs properly etc.
Speco, VDO, Sunpro, and some yum-cha brand make 3 cyl tachos, or if you're feeling crafty then Jaycar sell digital tacho kits you can solder yourself in next to no time.

Adjusting the mixture screw and idle on a carby isn't a difficult thing to do if you know the proceedure and that the carby is in good working order.
It can easily be explained if anybody would like for me to explain the process.

Hi Baz.
Yeah, thanks for asking.
Nigel did a fantastic job on the ol' Mikuni. - one of the galleries between the accellerator pump and the idle circuit within the casting of the carby body was blocked up with gunk - he had to strip the carby down and drill out the gallery to clear it. - 100 PSI of compressed air after soaking in Wurth's Carby cleaner overnight didn't budge it (no wonder it wouldn't idle) - Gave me a new appreciation of the term "clean fuel".
Car idles sweetly now, but I've also got a lot of crap in the tank and rather than drop the tank out to clean it, I've been swapping the fuel filter over every few days since getting the car back.
Nigel is a fountain of information - don't expect to be in and out in 5 minutes - if you show any interest at all, he will talk your ear off, but he does know his shit, and I feel was very reasonable price-wise.
I did ask him if, after sorting out my carby, he was still interested in doing more (because I would recommend him to this group) and he was not fussed at all - saying "work is work".
He personally doesn't like the Mikuni Carburettor, saying the whole Solex design really, is crap... but if you have one, and are not interested in changing it over to something else, then he can get it to go as good as it ever was designed to do.

I guess the big question is: how much did it cost you?
Also, it might be worth asking Nigel what carby he would recommend as a replacement for those who want to upgrade.

Hi Brayden.
The work included:
Strip / clean / rebuild all components of and the carby itself - i.e dismantled the accellerator pump and rebuilt that as well.
Re-sleeved the throttle shafts to remove slop and supplied & fit another new gasket kit. Reset the float level (I had it wrong) - The existing needle & seat in the carby were non-original and were the wrong length but I didn't realise that so I'd adjusted the float incorrectly - the float was sitting too low in the bowl - was still providing fuel, but not at the correct level. I wouldn't have known that, and the problem did not manifest itself driving around town, but if had tried cruising up a long hill for example at highway speed or under prolonged heavy accelleration, the carby may well have starved for fuel. Once he had stripped and then rebuilt the carby he found the idle circuit still problematic and so removed the carb for the second time and then proceeded to investigate further. That's when he discovered the blocked gallery. He then stripped again, drilled out the offending gallery and then re-plugged the entry point, reassembled the carby and refitted and then tuned the car (adjusted the timing etc I had set poorly 'coz I couldn't get it to idle properly!). In the process he replaced the fuel filter too. He also spent about an hour or more over two days explaining the intricacies of the carby to me - the effect and reason for the EGR valve etc and the correct way to fit new points (not how I'd done it!)... All good stuff. $235 well spent I feel.
I asked him what he thought of Mikuni carbies and he said Mikuni carbies were ok except they were modelled on a Solex design, and he feels there are many better designed carburettors out there than the solex design.
I asked him about an alternative carby - he said that for my purposes - using the car as a daily driver for the fun and fuel economy - the Mikuni would be fine and hastened to add that any carby modifications or alterations might provide more power, but at the cost of more fuel... so realised I wasn't into that angle. I think he said Webers go well.
