I hope this is finally the answer! I just read that other post again, sounds good hope it fixes you up. When you removed it is the spring and plunger in the pump or does it come out with the COV? And its simple to clean huh ill check it out.

 

It has a spring and plunger, mine looked fine and moved up and down fine, I spraved it with wd-40 and blew it off 3 times and put it back in, don't tightened very tight.
Starts in about 3 seconds when warm instead of 6 or 8 as before

 

Glad to hear it thanks for the information.
