They were beautifully built and finished.
I installed them paying particular attention to using quality cam breaking lube on the new cam and lifters. I broke in everything over a period of 30 minutes holding 2000 RPM, varying the RPM occasionally. Checked the valve clearances and all was good, After about 1000 miles my engine started making nasty valve noises. I checked the clearance and they were extremely loose. I checked the valve lift and all was in spec. so all I can conclude from this is the adjusters were not working as intended.
Has anyone had similar experience with this make of lifter??
Is there anyway I can tighten up the adj. screws without removing them??

Interesting. JAX lifters are Flathead Jack's new company. They sure look nice and their price reflects this, but it seems like you've got some bad ones.
I'd try to find some NOS or refurbed Johnson's. They work well and without issue for the most part.
