Skymaster gear door not closing

[mikec_myron]

Ref: 1967 Cessna Skymaster 337B. Gear doors wouldn't close on gear up after takeoff.

Thanks for the help guys. Problem solved! My gear problem was traced to the left main gear uplock switch rigging. I had checked it but after recheck found the switch was set such that it was only barely made and would open circuit after gear up, appearantly due to vibration.
