Triumph Repair/Spitfire distributor noise


Carter Shore wrote at 2014-07-26 15:31:55
The Spitfire distributor drive CANNOT 'jump' or skip, it's gear driven.

The VERY FIRST thing to check/set is the end play, it's set by thickness of the gasket between dizzy pedestal and block.

Too many folks assume it's 'just a gasket', and crank it down hard to seal.


That leads to grinding metal on metal, noise, rapid wear of the drive gear, dizzy bushings, oil pump, etc.

Too much end play is preferred over too little (or NONE in OP case).

Easy to check with only a feeler gage set.

Use original gasket as a template and cut thicker pieces with scissors or Xacto knife.
