Secondary Air Valve spring setting

(1/2) > >>

rad1026:
On a marine carb.  Any suggestions on a good initial starting point for the spring adjustment? 

Cliff Ruggles:
I set them at 3/4 turns from when the spring just touches the pin.

This assumes you are using a new spring.  Old springs tend to loose their tension over the years and it becomes difficult if not near impossible to find a good setting for them.   Typically you have to wind them too tight to prevent some issues when the secondaries come in......Cliff

rad1026:
New spring from the kit you just sent me Cliff.  I replaced the secondary meter rod cam.  When I reattach the air flaps can I use locktite on the screws or should I stake them or both?

tayto:
i personally just loctite them incase i have to disassemble in the future

rad1026:
I went ahead and did both.  Kind of a pain to set up the stake though.  Could have used an extra set of hands but was able to position it on my vise and get a good solid punch.  I'm hoping I don't have to take it apart again.
