Hi Norm and CM,

Good that we now have a fix for these primer caps and CM you are right about by having a very wide seat in the primer
cap, it will hold the needle up (sticking needle) as the early G4 cap with the wider seat doesn't let the needle drop
as quick as the smaller seats.

This is why I suggested a 80 degree cut in the seat .

I think the needle lever is a great idea as the 2 mowers I've fitted the Viton needle and lever in both start first time cold
with only 2 pushes of the primer.

I've heard some people use a 60 degree cut on the seat with a 70 degree needle but I'd like to try a few different
angle combinations to see what works best with the new caps.

The worst part with Chinese manufacturing is seeing the documentary's showing how the factory workers
are treated , it's not uncommon for workers to jump off the roof.
