Na I'm a natural tinkerer. I've now managed to remove the plugs put some 2 stroke oil in left it for a few hours and wow what a difference it now moves free. Can't get a spark from the plugs but the stop button is damaged. Is there a way to bypass it to remove it from the equation. Thanks

No worries

Do not worry too much if you can't get a spark there are plenty of potential easy fixes that I can advise of, also I have a spare CD unit in my garage if it gets that far

If you are so determined to get a 30 + year old motor running .. surely you could find that answer ?.. but dont waste any emergency services time when it all goes wrong please

FWIW the stop button was always a problem

For those interested I managed to got this running the other day. Although its only firing on one cylinder and obviously running rough I feel its a good start. I would like to thank all those who halped me solve the problems.

Ha,Ha well done you

Going off what you have told me via other means, I am leaning towards the condensor for that cylinder, it is rare that they fail to the extent that you do not get a spark (but it does happen) normally when they fail it just causes the points to burn out.

Have you had the coil for that cylinder off to see if if it has a 'pigs tail' earth? if it has it is very important that it clean (be carefull it is delicate) and that the surface it is sandwiched against is also very clean.

congratulations on getting it going I take my hat to you, have a close look at the wireing if I remember correctly the wireing on mine was falling apart, its not a big job but well worth a look, you got to get a video of it running and have the last laugh lol
