That second one is nuts.  They are more tricky to replicate because of the pin riveted in place.  A while back someone spoke with Joe Salva about replicating these.  I'll see if I can contact Joe about these to see if we're any closer now...

username?

Probably the same guy I talked to on AS in PM's about some other poulan aftermarket stuff. or maybe we have a 3rd guy now going to do up some AFM.  He said min order is like 500.

This was a part I wasnt interested in so I never said anything.

Sugar Creek Supply or Sugar Creek Saws.  Can't remember if he's registered here.  He's on House of Homelite and Chainsawcollectors.

OK I know SCS. He had hit me up for pics for decals before.

There is another guy on AS,  thinking of doing afm poulan stuff.   Besides the guy here making afm poulan parts already just not released.

Can you fellows advise on the correct ordering of diaphragm and gasket on this series?  I am doing my first one.  Service manual dated 1984 states the correct ordering when reassembling is gasket against pump body, diaphragm, then cover.  This pump had not been touched since  the factory based on the overspray pattern and it is actually opposite, with diaphragm against body, gasket, then cover.  The impulse channel cast into the cover is large and there is evidence of collapsing and puckering around that large channel.  I gather from searching on AS this can lead to crank pressure loss. 

As it stands, I troweled on Motoseal to fill the collapsed area in the gasket and set the puckered section of the diaphragm in additional sealant.  I did not reverse the ordering as indicated in the service manual.

Any definitive advice I could follow?

Thanks gents,

Cory

Sorry.  Didn't see this until now.
