just sent a 13mm pump out last week. stock timing gear. 2nd place this weekend. may have been a worn out gear.

 

So you have something to do with 13mm pumps but dont know anything about an adjustable pump gear?

 

Lets stay on topic and not hi-jack threads with what someone does or does not know.

If you can afford it, go adjustable. But make sure it's a good one. friend of mine has had his slip twice now
