Adjusting NPP valves to be just partially open
I did a search of this forum and on Google for info on how to install a stop collar of some kind on the NPP valve linkage so the valves can be adjusted to always be slightly open for a little better sound.
I pulled the fuse on the NPP, but that opens the valves fully, and it's too loud for me ... I just want the valves slightly open.
Anyone here know what people have used to accomplish this ... a photo would be even better.
Thank's

That's just what I'm looking for ... Too bad they don't show a photo of the 2 NPP linkage collars that are selling for $25 + $7.50 in shipping.
I will probably buy that, but I would rather go to the hardware store and get the stuff I need to make my own (might cost me $5).
Sure wish i had a photo of what that guy is selling ... or what others here have made themselves.
Ron,

I thought I read this leads to rattling linkages at idle???

AORoads ...
So, you have this installed. Can you be so kind as to post a real close-up photo of the collar installed on your NPP?
Did you buy the collars that the guy is selling for $25 + shipping ... or did you make your own?

Here's what I did (temporairly) with a clamp and wingnut from my junk Drawer, works the opposite of the collars in that it sets the maximum sound, applying vaccum shuts it off. No vacuum connection necessary if you want to run this way all the time.

They look just like drill bit stops that any hardware store should have for about $2.

Ok ... a 'split collar' ... that's the ticket!
I wonder if Lowes or Home Depot has these in stock for the diameter acuator rod found on the NPP?
BTW ... anyone know what the actuator rod size is?

Any chance you could give us CF members a break on the shipping cost?
$7.50 shipping to Florida seems a little high for a couple of small collars and an allen wrench.

Drifting
two small u-bolts
For less than $1 and including the 4 bnuts and four lock washers for the u-bolts; just installed them over the rods to hold flapper ~25% open when running ( sounds just about right to me). Adjusting is a simple case of loosening the nuts and sliding the u-bolt one way or another.
My question, is there any risk or possible damage by keeping the flapper always partially open???
