What have you done today with your Austin Seven
Hi All

Checked the tappets on the Special today. Not that easy as the bunch of bananas manifold and semi updraft SU make access to the cover impossible so had to come off.

The gaps were way off. The reason....the silicon block to case gasket. I had tightened the block to case nuts several times during the rebuild but 200 miles on and I got an extra 1/4 turn on most.

I have also found that the backlash on the timing gears seems to have opened up slightly (7 thou) and the distributor gear backlash much more  Huh.  

Is it just noise that excess backlash causes or is there likely to be more serious consequences?

Cheers

Howard
