76 repu problem

My 76 repu seems to want to stall (and sometimes does) if I don't pull the choke. It kind of sputters and the RPM's drop and then it will kick in and go. It runs perfectly except for initial starts. Does anyone have any suggestions as to what may be causing this? The carb is not new, but it is super clean.

Check to make sure the accelerator pump is sqirting properly into the primaries.

Thanks, I did and it doesn't appear to be squirting properly. Do you know how I could get it to squirt properly or do I need to replace the pump. Can you replace just the pump or do you need to replace the whole carb?

You can do this with the carb still on the engine. (I did mine 2 days ago). After you get the air cleaner and vacuum hoses off, unbolt the choke heater unit and take off the choke/throttle connecting rod. Then undo the throttle/accl. pump rod (don't loose the little washers).
Now you can undo the screws holding down the top of the carb air horn. Don't forget the center air cleaner hold down bolt. And carefully tap loose the top plate of the carb. As you pull it up, the floats will come with, probably part-of or all of the gasket, and the accl. pump plunger will want to catch in the bore as it all comes out. Go slow and try to get a rag underneath. It's real easy for the float hinge pins to fall out, and the floats to fall off. If you pull it up in a hurry, it'll all go flying.
Use a rag or something to sop up the gas in the float bowls, next look down the accl pump bore and you'll see a long spring, a hold-down plate, and a small plastic check-ball at the very bottom. Don't lose this stuff.
You should take this time to squirt carb cleaner thru all the passages. However, you'll probably find the rubber plunger is disintegrating, and gas is bypassing. Oddly enough, I've found several repair kits for these carbs in parts stores, and I think you could take the accl pump parts in and match 'em up with Courier parts.
Let me know how it goes.

carb rebuild kits

I had the same problem and purchased a rebuild kit for $15 at CarQuest. The kit has everything in it including the pump parts. When you order it ask for the kit for a RX4, it has the same engine and carb as our repu. For some reason the repu isn't listed in their computer. I checked out napa and autozone and found out the same problem, repu isn't listed. The RX4 covers the same years as our trucks. Good luck.

Thanks all for the feedback, I will be working on it this weekend. I think I am going to go and order the rebuild kit and go from there. I'll let you all know what becomes of it...thanks again.
