[Healeys] Accu Spark kit

[Larry Varley]

Hi Guys, has anyone had experience with the Accu Spark distributor 
conversion for pointless operation on a BT7? I bought a kit out of 
curiosity, which was quite cheep and found that the firing ring that 
fits over the distributor cam, is quite a loose fit and can rotate a 
little on the cam, so I can't see how it could maintain regular timing. 
Has anyone successfully used this kit? The concept looked good as there 
are basically no modifications or extra wiring, and the sender unit fits 
well on the points plate.
Cheers
Larry
