Right High Speed Turn !

G Guest
my question is: What is the proper setting for a motorcraft OEM 4600 carb float valve
on my 1974 Pantera L I rebuilt the carb and need the proper settings?
The car runs great straight and left but on right turns at full throttle it flattens out and starves for fuel.
Prior to me rebuilding the carb the car was stored for 10 years and did not run. I have gone thru the complete fuel system along with other systems on the car, but after I rebuilt the carb with the settings suggested it spewed gas everywhere, so I set the carb up to just not leak gas out when you remove the top plate but I don't think it's high enough.

Thanks and I have learned a lot from you and the other owners that have posted on your site
Sincerely,

Joe,

Unfortunately, the problem you're experiencing is the nature of the beast. The only known solution is to slow down in corners, and what fun is THAT?

I suggest you retire the original carb, or sell it to a concours guy, and invest in a decent Holley; make sure it is one of the models featuring center-pivot floats (i.e. not one of the cheaper "economy" replacement carbs) or you'll be right back where you started.

Depending on the extent of your motor modifications, a 600-700 cfm will probably be best.

Good luck!

Mike

Sorry, Joe. Running the OEM Motorcraft carb, you're definitely in the minority among Pantera/Mustang drivers. In fact, there are few shops that even recognize the Motorcraft, stock parts or work on them at all. Of the 140+ Panteras in the Nor-Cal POCA chapter, only one runs the Motorcraft. Your symptoms point to fuel problems, either starvation or momentarily rich due to float bowl overflow into the throttles. About all you can do is play with float heights to mimimize the effect, or avoid the situation. Or change to a more mainstream carb...
