Aborted MOT

[Matt306]

Booked for another MOT on Monday... fingers crossed.

Let us know how you get on and if you find anything to explain the ignition timing problem. If the pulley had shifted is it possible the valve timing will be wrong as well?

[Matt306]

Entirely possible i suppose, but I am not sure as it was sounding much more healthy after my tinkering. I reset the carbs again and have her down to idling at 1000rpm. I suppose i may have to try the screwdriver in the spark plug hole to be sure the timing mark is in the correct spot.

Yes its highly unlikely but worth checking...

Hopefully this helps. Can't find fault in what you have done so far.

If the dizzy is 90 or 180 degrees out with the plug wires in the prescribed position the engine would be rather reluctant to fire at all.

Thanks Beans, took me a couple of moments to remember you are LHD! 

I contacted Steve at S&S to pick his brains too the response is useful to anyone else with a similar problem;

"Hi Matt, the Rotor arm pointing is not an exact science. If it is running fine now then it must have been 1 tooth out on the dizzy."

 

I booked the MOT again and took her on the open road and she pulled well getting up to speed nicely, i was quite surprised how well to be honest.

I now have a nice MOT ticket , obtained tax and we are road legal.

 

Going to shake down some gremlins now, when its a little warmer it will be paint time.
