SU's from an MGA maybe originally installed on an early MGB, my latest project
Lars you sure you cant work some of your magic on these things?

No doubt FI is more efficient than any carb, but, to retro a carbed engine can be pretty pricey and unless you go with one of the new smart systems can still be a lot of work getting right. And those smart systems? Figure on spending about $3K. My Qjet runs pretty darn good especially when I'm looking at thousands to go FI, doesn't it Gene?

I have two Q-jets sitting in my garage. One I believe to be original(off a 1980 L-82) and the other well who knows for sure. I would be more than happy to send them to you. I don't have any use at the moment for either. And unless you tell me that one or the other is in really good shape for a rebuild. You can use them for parts or donate them to the cause. I am running a Holley Carb at the moment.

Bobs77Vett,
That is a very rare MGA coupe! Have not seen one in years. I had a 1962 1600MKII many moons ago but a roadster. And an early MGB. Fun cars. Yours is rough but looks basically solid. Have fun with the restoration.

I'll mount Paul's Pretty Carb (now to be known as the "PPC") on the run engine in the as-received condition and give it a test run and a photo shoot. I'll start a new thread with test results and photos of the teardown, along with a technical evaluation of the results. I'll then go through the correct setup and repair process to fix whatever we find, and we'll then give it another test on the run engine. Should be a good technical write-up, so watch for it in a week-or-so...
Good participation and comments from everyone in this thread - thanks for all your notes and posts!

One day I come back from a ride and pop the 'bonnet.' Those $%"*# SU carbs were peeing gas out of their overfill pipes - missing the hot manifold by barely an inch. A microscopic float needle had malfunctioned. After rebuilding the carbs I sold the car.
Anyone who complains about a QuadraJet (which, in my opinion, is the StarShip Enterprise by comparison) hasn't had to deal with 1930s era carbs. Oh, and those 'oil-pots' were - as the Brits say - 'charming.'
Jes'. Sayin'.

Owned a '52 MGTD for about a decade. Enjoyed that little beast; never buggered it up with an MGA differential, though, which made it freeway incompatible. I'd cruise it at 50MPH on the back roads as angry tailgaters jumped the double yellow to pass me.

About two years ago I "almost" replaced my Corvette with one of the last Triumph TR6s. In fact I lost an EBay bid by just $100.00. I loved those last ones but strangely I was glad I lost. It is hard to get service and parts around here.

I've been gifted with a stature that prevents me from enjoying classic English sports cars. My line of sight drops dead even with the top of the windshield frame in my firend's XKE.
He enjoys it, though.
I definitely think a QJet makes loads more sense than the CD (constant depression!) carburetors, but it was still fun to work on. The tool I use for reaming throttle shaft holes on QJets indexed and cut perfectly on the ZS carb - same throttle shaft size (5/16) as a QJet primary.

You forgot about the Lucas Prince of Darkness. He was a treat to deal with.

"Why do the Brits drink warm beer? They have Lucas refrigerators." Don't get me wrong; I love old Brit machines - mostly for the outright crudity of the designs. I've had several, including a '66 TR4-IRS. One day, while traveling over the Bay Bridge, one of the half shafts became 'I'ndependent and parted company with the 'RS.' Loudest, bang/bang/bucking bronco ride I ever had. Then, of course, the Lucas-Loom failed at the worst possible time - in the hi-speed lane of the 101. Miracle I'm here today. But a fun ride while it lasted.
Good thing you lost the TR6 auction. By the time Brit became Leyland, the Limey Auto Industry had fallen to an historic low. Union problems, disgruntled workers; bolts deliberately left in transmissions. You really didn't want to be there.

Thanks Lars...received the Qjet and factory distributor you rebuilt. Soo looking forward to feeling how the car responds. Next time we meet, I'm buying the beer..
