Re: Rebuilding 2300 List 2977 Carb
We'll hold yore hands Tren!
Main thing is to TAKE PICS and document your first effort, that way you KNOW what ya got along the way and can compare with stuff I have here for samples.
Do NOT attempt to remove either the choke butterfly or the throttle butterflies, though you do need to verify that the screws are extremely tight.
Remove the nylon accel pump cam from the throttle arm, noting which hole the screw is in, that cam needs to be carefully inspected as well as the actuator arm, for wear.
Many of the pints are covered in that 23XX thread also, especially the accel cam/arm interface.
Be sure to remove the accel discharge or "shooter, and carefully remove and set aside the check valve that is underneath the screw. There are THREE different checks used on these carbs, you MUST use the one that is correct for that main body.
Those kit instructions cover all variations of the 2300, not specifically your 2997. So use that info as a reference, it is NOT an absolute for your exact mixer.
You will prolly find all the throttle body and fuel bowl screws loose. That is a common "problem". When ya go back together with it we'll discuss how to handle that.
The accel pump well "check" in your carb will either be a small ball bearing encased by a retainer, or a orange silicone rubber "umbrella". The ball is captive, no service required as long as it's not corroded/stuck. The silicone check will be replaced with the new one in the kit.
The throttle body-to-main body gasket you select from the kit must be an EXACT match for the old gasket. EVERY noob has a problem with that, ask Trever and Drew! Any carb is a precision instrument, so you can't be too clean in your re-assembly techniques. Same for cleaning all parts. THAT is the difference between "works perfect" and "parts donor".
Here's copy of the worksheet I use for Holley modular carb service, works for either a 2V or a 4V carb. Record the important inspection points as you pull it down, then you will know what the setup on it is for future tuning!
