TR4 (and 4A ?) bonnet sticking

[alaric]

My recent battle with the mysterious misfire was extended for a while when the bonnet was stuck in the closed position.

Not caused by the usual cable problem.

In my frustration with the misfire I allowed the bonnet to slam shut instead of lowering gently.

It bit back and the pin and collar went beyond the tube on the underside of the latching mechanism, and stayed there.

Fortunately TRGB's previous experience and expertise was able to spring it free again, much to my relief. I was at the point of believing that the only solution was the angle grinder!

TRGB then fitted a TR5/TR6 item which has a slightly longer tube which prevents this type of lock down happening again.

I imagine that most owners are not even aware that this tube exists, can't be seen when the latch bracket is bolted to the bulkhead.

My strong advise is to change/extend the original tube for the 5/6 spec length.
