I spent some time this weekend breaking in my FZ63. Now that I am ready to put the cowl on my plane, I have noticed that I misplaced that little spring clip on thingy that goes on the needlevalve(part 62 on the diagram). I haven't had any problems with the needle wandering without. Is it really important to have one? If yes where can I get one? Thank you in advance.

It might stay put for awhile, but it will loosen up and cause a problem.

Call our service dept at 775-782-4562. They can get one to you.

Thanks Dave!
Your response prompted me to do some trash can diving. I found the part later in my toolbox.
