RV-4 tip over canopy. When I got it canopy latch worked fine. Canopy warning light went out. Fifty hours later I noticed that the light occasionally didn't go out. Canopy seemed to be fully latched. Later had a problem getting canopy to latch. Greasing pins seem to solve the problem. Now I have the panel in front of the cockpit off, I can see where the front pin and micro-switch for the warning light are. Everything seem to be working fine, no obstruction. Same for rear pin.
Here is the problem. With the canopy open and the canopy latch in the closed position the outside handle is parallel to the direction of flight. When I close the canopy and latch it the handle if off 20 degree or so from latched. The outside handle is indexed to the shaft with a through bolt so it can't be off.
I think the culprit might be the middle pin on the roll bar. Help!
