Expert Posts: 1476 Location: Pacific Northwest Hey there everyone, I just got an NOS carb off of ebay and I am wondering if I should do anything to it first before I just install it? I was thinking that considering it's age I might want to pull the accelerator pump out and soak it first but what else?

After a week or so, pull it out and empty it, go over the screws and give it a try Paul Hettick Posted 2016-12-17 6:28 PM (#528993 - in reply to #528962) Subject: Re: NOS carb rebuild?

Bolted, fueled and it went off without even a hickup. All I had to do was set the curb idle. Oh, and swap out the air cleaner. Seems the NOS carb has a vacuum pot on it that the other carb did no have and my air cleaner wouldn't fit.
