Stromberg woes

The reason I replaced the Strombergs with the Weber was that I could not see the value in overhauling 42 year old carbies. The Weber is brand new in every way. It is smooth and the car just pulls easily up to speeds we are not supposed to go to. Look forward to hearing from others that have fitted the Weber.

Leon H.: As you know my Weber conversion was also not straightforward. The car would run quite well but was an absolute bugger to start, no matter what little tricks I tried with the choke and throttle. I gave it to Richard at Fairfield and he then passed the car on to Thornbury Carburettors. He re-jetted the main jet ( I think 2 sizes down??) as it was getting too much fuel. It now starts nicely and I expect fuel economy to improve too. This is something for others to bear in mind if they buy the Weber, but I completely agree that it is a better way to go for those who don’t mind some mods to their vehicle, rather than overhauling the Stromberg’s due to their various issues.

Yohan E.: It would be really interesting to hear from those in the club that have the Holley fitted to their Stags to see if they are happy with the results or if they also have experienced issues. Kindest Regards, Yohan

Geoff B.: I have decided to persevere with the Stromberg original not sure if right or not but will do it anyway. Has anyone used Wilson Carburettor Services in Airport West to restore Stromberg’s and are they ok. Or is there a better option.

​ Enjoy the emails and interesting discussions. When I purchased my Stag nearly 3 years ago, it was running very rich and a little roughly. I found that the diaphragms in both Strombergs were split, so I replaced those, adjusted the mixture on both carbies and touch wood, no issues since. Even when its been sitting for a couple of weeks, I pull the choke half way out, don't even hit the gas pedal and it starts first kick. Its like all things in our beautiful machines, they need regular maintenance checks.

I have never had a problem with the Stromberg’s and figured I have enough on my plate trying to finish the full rebuild: Engine balanced and ported, headers fitted, sports SS exhaust, leather dash/interior nearly done, comprehensive stereo; 2 amps, 9 speakers, pop out touch screen, standard BW35 rebuilt, original brakes and profile Michelin tyres, integrated AC, Sundym glass etc etc.

Have used Wilson many times Geoff, mainly when they were still in Carlton. They do definitely know what they are doing there if the original people still run the show. There was a workshop on Melville Road Brunswick (West Melbourne) if I remember correctly who did an excellent job on rebuilding my Stag carbs – when he closed down I started going to Wilson.

Jeff R.: I have a holley 4 barrell carby and pan cake air fitter thats as been jetted and set up for a stag. Only done about 5000 km., for sale if any one is interested. Jeff Sent on the go with Vodafone

A Stag owner: I have original Stromberg carbys on my Stag, the jets have been replaced and I pull out the choke half way and it starts like a dream. There is no need to play around and waste money on Holleys or Webbers , for around $400 you can get the Strombergs overhauled and they will be like new, the classic look of the Stromberg carby look great

Dave M.: Wayne, with 3 connections to a charcoal canister you have a post 1976 emissions Stag. One connection is to the fuel tank, as you guessed. This has a small brass orifice piece in the tubing, just near the brake master cylinder. This is the fuel tank vent. It should stay connected to the canister. It allows the tank to breathe and should not be blocked, or you get fuel starvation or fuel pumped out of the tank. One connection is to the rocker cover and the 2 carbies, and the RH rocker cover, 1/2" diameter. This is the crankcase ventilation.You can re-configure this so it has a single connection to the copper pipe shown in Graeme's picture, and the other end to the canister still. One connection is to the 2 carbies float bowls, 5/16" diameter. This is Stromberg specific, so can be blanked at the canister. If you want to remove the canister, and fit an oil catch can, that's a different story again. The purpose of the canister is to trap fuel vapour and crank case vapour.

Wayne Ref to your 155129 to my 100_4229 I don't have a vacuum advance on my carby so I have blanked it of. You are correct the rocker cover outlet goes to the air filter. I have added a pressure regulator and gauge. My pump will not pump over 2 psi and that is not enough for a Weber let alone the Strombergs. I have been told that the Weber needs at least 3.5 psi. Yesterday I bought a Goss Pump GE239 that is rated to 4.5 to 6 psi. Supercheap have them on special until the 14th May for $73 a saving of 15%. The Carter pump that is rated to 6 psi was going to be $146.00. Hopefully fitting the pump tomorrow after the Tech Morning at the Resto My Ride workshop at [address removed] Williamstown. If any one is free come along at 10.30 am but let me know as I have to cater for a sausage sizzle. Wayne trust that you get the car running well.

For those that are having issues with sending to multiple addresses in the interim just sent to me and I will forward out. Yesterday I fitted the Goss GE239 4.5 to 6 psi fuel pump to the Stag. They were on special at Supercheap for $73 a saving of 15%. Sorry about the quality of the photo. I was going to get the Carter Pump but they were $145.00 I now have 3.5 psi as suggested by the dyno man at the Weber carby. Stag definitely started quicker. Maybe I should have bought a better quality regulator as I had to set the pressure regulator to 4.5 psi to get 3.5 psi on the gauge. With the old pump I was lucky to get to 2 psi. [name] in WA has just fitted the Weber to his yellow Stag and kept the anti pollution gear on the car. He had major issues with his Strombergs.
