I have the small Jet 1-A retracts in my Grumania F-100 with just over 20 flights on them.
These are air up, spring down units.

The problem that has occurred is that the main units are not lowering with consistency when I release the air pressure.

Has anyone had a simialr issue and what was your resolve to this problem?

I sent an email to Digitech and he has my issue resolved.

Thanks,
Bob
