Dual carb (re) installation.

My 1980 tr7 has dual carbs. I removed them to send them out for a rebuild. When I unbolted the carbs and removed them, the linkage fell out, before I could take pictures, or get a look at the sequence of the bracket, the spacers and the bracket for the fuel pressure switch. It's not intuitive at all! Anyone have picture or know where I can get a good schematic? The manuals I have do not illustrate the linkage. Thanks!!

What type of carbs, & where are you Mjmartin316.

Where is this fuel pressure switch, I've never seen one on a carb car.

Hi,

Welcome to the forum, what can be handy is Rimmer Bros web site for this type of thing. They use pictures from the original parts fiche and catalogues and will at least give you an idea. As my learned friend say's what carbs are we talking of as have original parts books here I can scan.

I believe that your "fuel pressure switch" is really the A/C kick up solenoid that activates when the A/C is switched on.

You're correct, that's exactly what it is. As you can see, this is very new to me....my first crack at a foreign car and a British one, at that!!!. The Red ROM manual you refer to, what is this? Now that I realize it's an a/c jack pump, I know where it goes, but there are 2 spacers, the bracket for the jack pump and the bracket for the throttle cable / linkage that all mount with the same 2 bolts....it's this sequence that I cannot figure out and none of the pictures I can find, show this assembly. I am in the USA and its dual stromberg 175's. Its a 1980, Tr7 Spider.

Thanks, John, I appreciate the help. They're dual stromberg zenith cd 175. It's a 1980 tr7 spider. I've scoured the Internet a bunch and not found this setup yet. Any pictures you have would be awesome. It also has a/c ( thanks to Clara, below, for helping me out with the solenoid)

Not necessarily so, most cars sent to Oz have Zenith/Stromberg CD175 Carbies.

Canada also got the Zenith (US) carbs as their emissions closely follow the US to simplify the building of some Detroit models in Canada that were then shipped and sold to US. Interestingly we did not get FI in '81 (except as an option) so they must have been a little less stringent. A friend had a dealer sheet stating that for the Spitfire the SU carbs could be specially ordered instead of Zeniths. Probably not an option for TR7 with the FI available (but seldom seen in Canada). I know of only one Canadian TR8 that was FI (it could have been a US model that was directed to the dealer. instead of an actual Canadian model).

Probably means you haven't lived in Oz or Canada.

It probably you didn't realise how sloppy BL marketing really was, when they restrict some of their export market by not exporting the best option for each market, & just sending the US model.

So don't be too humble, but yes, just like our cars, you are getting old, but only in the same manner as a good wine of course.
