Morris Minor Owners Club

Just one simple question. I have lost my bit of paper showing me which lead goes to which plug having took them off to replace them with new ones I know I should of done one lead at a time at a time. I know the firing order is 1342 and it is anticlockwise the leads come out of the top of the dizzy cap, so how do I determine which one goes where. I am on my two rest days Friday and Saturday so I would like to get the old girl fired up this weekend as the engine is now back in the car. Thanks

Remove the rocker cover and turn the engine over by hand so that the timing mark comes up to TDC with both No 1 cylinder valves closed, that is the compression stroke.
When at TDC look at the rotor arm. It will be nearest to 1 on the distributor cap. Then go anticlockwise, as you said, 1-3-4-2

Just do it trial and error! Statistically - you should get it right by the third attempt! A lot quicker than messing about with the rocker cover........

Have to agree! The rubbish leads I bought a while back came off while I was messing with the car at the side of the road (condenser had failed) no way was I taking the rocker cover off there. I eventually got them back in the right place... after a spectacular backfire

Okay, point taken, so without removing the rocker cover, at TDC the rotor will point to 1 or 4, that way you will get it by the second attempt!

Cheers guys if the rain keeps off I will try it. Gloucester seems to be holding off the rain until later.

If you can find TDC - then yes!

And whats the valve clearance on both inlet and outlet if I want to run it on unleaded. It is not an unleaded head, but i,m sure I have read somewhere to run it on unleaded you only need to adjust the tappets. I,m getting there slow but sure.

12 thou on the inlets and 15 thou on the exhausts
