K....next question up....little 2bll carter carb....never done a rebuild on a carb so bear with me...in learnin mode...
Normal - not wear.
I'm no expert carb rebuilder. I can usually take it apart, soak it in carb cleaner, blow it out with the air hose and get it back together ok, I fall flat on my face trying to get it adjusted properly. One of life's great frustrations I've never mastered.
Anyhow a couple of my hard learned tricks.
- I use a cookie sheet with a 1/2" lip with a shop towel lining the bottom. Keeps parts such as little balls and springs from wandering away. The shop towel stops "things" from bouncing when fat fingered and dropped.
- Take many, many pictures, can't ever have too many pictures.
- Match all the gaskets you remove with the replacement in the kit.
- Make sure all the holes match. If there is any doubt which way is up, mark the new gasket with a sharpy.
- On reassembly, tighten screws evenly and not so tight that the gasket gets distorted. Too tight is worse than too loose, air leaks are your enemy.
Other than that, you are on your own!
