Title: cox medallion .049
Post by: bob werle on July 15, 2008, 09:11:19 AM

Does the spraybar in the medallion press out or is it threaded?  I have a medallion w/out the spratbar and I also have a plastic venturi assembly with the n/v and spraybar.  I thought it would be easier to just replace the n/v,spraybat than the whole venturi assembly.

Bob,

ASIR, it pushes in from the fuel nipple side. There's a shoulder where the fuel nipple meets the red palstic, correct? the needle/threaded side is smaller diameter than the knurl next to the shoulder.

If you push in a new spraybar, remember to check where the fuel jet hole or holes wind up. There's been discussion about this, probably in this topic somewhare...

Luck!

I tried to push it out from the opposite side to the fuel nipple and found out there is a snap ring holding the spraybar in place It doesn't just press out.  The snap ring has to be removed first then it just slides out.,
