Subject: Re: M45 Distributor Skew Gear
Thanks Colin,

I am most interested in how Stephen's distributor had backlash when his skew gear was ok.

My guess is that it was the cam that was twisting on the distributor shaft spigot. This is fine if the automatic advance is used as it enables the weights to throw out as required. However, as the M45 has manual advance and retard the cam has to be permanently fixed to the spigot after the weights have been removed or welded up. It seems likely that whatever was done to achieve this on Stephens 'original' distributor had failed. Hence the need for the replacement correctly converted for use on the M45.
No doubt Stephen will advise if this was the problem...plus as he says it was also a 'cheap Chinese copy'

Of course wear in the skew gear has to be significant to have any significant effect on running as it is simply driving in one direction at a constant speed. Grateful for views on this assessment.

As for the Scintilla GN6 ...if anyone has one available I would be most interested! (Y2 in the register)

Best wishes
Mark
