Turbo carb question

[Oldshep24]

I’m in need of a detailed exploded view of the Carter YH carb. After installing the Holley fuel pressure regulator the car runs much better, but still way too rich. We’ve installed a new carb kit but perhaps we missed something? Thanks in advance.

You should post more info on your car…

However, if you have an EM, you can get turbo carb info here:

As in my other thread, my car is a 63 Monza Turbo. Was running terribly when I got it, and we started the usual steps in trouble-shooting. Last thing we did was to get the Holly regulator, which helped a great deal. However, the car is still not functioning correctly. The idle mixture screw can be screwed all the way closed and it makes no difference in how the car runs. So, we need to get into the carb more extensively. Hence the request for an exploded view of the carb.

Page 9-18 of the fuels section of the 62-63 shop manual supplement as linked above. Simply installing a kit often does little to fix a faulty carb. the carb must be rebuilt, which means using the manual and a kit, thoroughly cleaning and checking and fixing the adjustments while installing the kit parts. Perhaps you will find your issue when you take it back apart , verify the assembly and do some adjustments.

One thing you can check before taking the carb apart- with the air cleaner off, and the choke open, look at the venturi at small throttle openings... if there is a lot of gas dribbling out of the venturi, there may be something going wrong with it that cant easily be fixed. Theres some sort of internal passagway related to the accelerator pump that can get messed up.

It's can be fun to learn something new, but sometimes it's best to just call in the experts. The YH was revised from one model year to next. They can be a challenge!

Steve Goodman at Rear Engine Specialists in Colorado has a lot of experience with Corvair turbo systems, AND a good reputation!

Call him and ask about sending your carburetor to him for a rebuild.

Also note the 62-63 Turbo cars did NOT use the same ignition ballast and coil as the other Corvairs. After all these year who knows what someone has changed (the original ballast and coil had a reputation for short points life). So you need to determine which coil and ballast is in your car. While your at it check the distributor number.
