I'll get those codes tonight for sure.

Yes the engine has compression - I havent measured it but its more than reasonable from my observations. Its only a couple of years old. I will put the gauge on tonight.

The previous owner assured me it was running but used to stop suddenly. I put that down to a loose connection on the spark plug which I have fixed. I was surpised it even started the HT lead clip was so loose.

Do you have a method to clear the breather pipe? I didnt think of that reason.

Thanks as usual.
