18RG carby issues

[shewiththe18RG]

Started with the solexes, had them dyno tuned and running GREAT for about a week, then the car started running like hell and we ended up rebuiling the engine, asuming it was big end bearing but not knowing for sure. There was damage so we assumed the car would be sweet once rebuilt, its never run at full potential since.

Recently bought some delortos i found for sale here, the guy didnt know what they were jetted for so it was no surprise that i could hardly get the engine running with them on. I thought, stuff mucking round with them and hassling my dad, i'll pay someone to dyno them and have it on the road sooner.

Trust me to pick the dodgiest guy in castle hill. filled me with false hope. He had my car for 5 weeks and i got it back in worse state than when i gave it to him. Luckily he didnt get any of my money in the end, and I got a free fuel pump out of it.

But now im just sick of playing with old carbys and i applied for a loan so i can finally get much needed work done on the car. I'm thinking new webers. brand spankin new =)
Can anyone help me with what's the best size for the 18rg, 40's, 45's?

Anybody know a true 18rg guru who can get in new webers, maybe with a dyno? in the 3 years of owning my car its only been running perfectly once- FOR A WEEK. everybody recommends frank kleinig, but i got in just before he retired when i had the solexes tuned. It's getting harder and harder to find people who are willing to tune carbys, well tune them well. Especially the solexs and delortos cuz you cant really get parts. That's why I'm kind of quitting trying, and seriously contemplating the new webers.

I'm sick of all this mucking around, i'll spend the money, i just wanna drive again.

Any help would be greatly appriciated! Thanks, Tiffany.

nooooo... a pair of new webers?

As nice as a carbied 18RG is, if you're looking to spend that much on new ones + pay someone to tune them, I'd suggest to go EFI. I know it sounds like a lousey cop-out, but I've seen many complete running EFI 18RGEU's for under a grand. I don't think you'd get a new set of webers for much less than that But that is just my suggestion.

If you do decide to go carby for historic sake, I know there are a couple of *ahem, more senior * guys in the Canberra Celica Group that know their way around celicas and carbies. I won't post their names for fear of getting hassled by everyone with a rough set of old solex's, but if you get a new set i'm sure they wouldn't mind passing on some tips to a fellow toymodder.

Cheers,

Thanks Timbo,
My heart is with carbys though. Fuel injection isn't my style
I was told new webers are about 800 EACH, so this really is the expensive option. I'm sick of trial and error though, and don't want to risk buying another dodgy pair of carbys.
New webers, am I crazy?

I just paid $520 for a fully re-conditioned pair of 40mm Solex's...

There's also a guy here in vic who is a Weber specialist who quoted $750 for a fully re-conditioned pair of 40mm Weber's... (He has a track proven record)

I would seriously reconsider buying new gear when there is an equally as good option for less than half the price!

Hi,

Onya sister.... none of this gay EFI crap for us old scoolers!!!

Frank, although now retired, I think does the odd job or two from home. Didn't he do these carbs not so long ago?

PS: Check this thread. It has some 18RG solex tuning info and pics.

Yeah, a year or more ago. That's when everything was running perfect and I was on my way to WSID to give it a run when everything went bad =(

Knowing the potential and not being able to get it back is so frustrating!

[river]

Hi,

What makes you think it's the carbs? I assume that when Frank did them he rebuilt and tuned them. Unless you've pulled them apart or frigged about with them they should be fine.

When the engine was puleld down and rebuilt did you get the timning done properly with the cams? I'm wondering if this is where your problem lays, rather than the carbs. I'm assuming here that the carbs have been untouched since Frank did them?

We had a major blow out in one of the carbys, the jet housing. frank said they gave him heaps of greif, and when he made up a new gasket somehow pressure blew the whole housing apart. i should have taken some photos, it was pretty nasty. and since then there has been a lot of playing around with them. my dad is pretty cluey so i trust what he's done. he was always more familiar with dellorto and weber though, so when i saw the dellortos for sale for so damn cheap i didnt think twice!
We've had other fuel related suspicions though, and over the last year I've put in a new tank, and checked lines, now a new fuel pump. It's mainly my patience that's running out. I miss driving my car sooooooo much. I think I've had it on the road for only about one month this year.

Hi,

Hmmm.... I'll check some stuff I got tomorrow and let you know.

You can get new parts for your dellortos, i got new jets, air correctors and gaskets sent from italy last year.

[shewiththe18RG]

Can you give me contact details of some sort? I've been having a hard time finding second hand jets and stuff let alone new! Cheers matey.

[rollin_stock]

you have pm!

I was told new webers are about 800 EACH...

New webers, am I crazy?

Do you really want to know the answer? no... REALLY?

Just kidding, we all have our passions, and none of them really align with practicality.

Do you think I was smart for throwing over a grand's worth of parts at my 18RC to have a single-cam, single-carb firebreathing monster (that chews through stupid amounts of fuel and would be lucky to put out 100hp ) ??

Do you think River drives his RA25 because replacement parts are easy to find, the engine is super economical and thieves don't even think twice about it? Come to think of it... Do you think River actually DRIVES his RA25 hehe

You have a passion for twin webers... which is a perfectly understandable passion

As River suggested, timing (both cam and ignition) can play a huge role in how these engines run.

The bottom end is very strong in the 18RC/G's and providing there's no knocking, that should be fine.

18RG top end's seem to be causing a few dramas these days as 30 years of hard revving and ill-adjusted valves, some of which no doubt has been with unleaded fuel, is taking it's toll. Give it a quick compression test to give you an idea on how the rings/valves are going.

If the engine seems ok from this, maybe see if you can ask a favour of someone close by with a known set of good carbs. For the cost of a gasket and an hours work you could find out if it really is a problem with your carbs. Just make sure there are no vacumm leaks and that fuel supply is freash and clean. If all is good, by all means fork out the dosh for shiny new Weber's Then post some pics, cos i'm sure many members here would get turned on from the sight of two age-deficient top-notch carbies

Hope that helps

i have 40mm webers on my 18rg-when first fitted were well out of tune very hard to drive until they were tuned and have not had a problem since that was about two and half years ago he changed venturis and jets around until it worked
place where this was done-brett
Tassell automotive
unit E6 2A Victoria Rd
castle hill
9894 4273
tthese details are from when ihad work done hope they are the same
also recomend-Stuart Wilkins Rally at Mcgraths hill
if you want new webers there is a place at hornsby will found out
hope this is some help Steve

[shewiththe18RG]

Thanks heaps guys.
Tassell at castle hill seems a good option cuz he buys stuff from my work, could probably drop a name or two hehe

You've all convinced me to give second hand carbies one last shot.Throwing borrowed money around seems fun but would probably drive me nuts down the track.

Thanks again
Tiff.
