Dear All,
My 1976 SS1 has been getting more and more gutless lately. Engine starts and idles nice and smoothly but lacks mid range and top end woooosh. Hills becoming a problem too. Rang up a Lucas specialist here in the UK. Very helpful and a good source for quality caps and arms : http://www.distributordoctor.com/ which I duly replaced along with the plugs and leads. Always a good starting point.
The good doctor reckoned that this type of Dizzi is prone to a sticky advance and retard vacum unit. Having only recently acquired the car I do not have a good manual (any recommendations?) and the online manuals I have seen are a bit sketchy in this area. I need to check to see if the unit is advancing fully. Trying to find the timing marks, I can see a mark on the crank pully but not sure what I am looking at, TDC, the idle advance mark , full advance mark or what :?:
So firstly if somebody could please help me work out which mark is which I'd be grateful,
and secondly I need to know what total advance I should be looking for once the vacum (and weights if there are any) is all in, at what RPM, and if there is a total advance mark to check that against.
many thanks.....
