Hi all, I have a Ransomes Auto Certes (Mk 8?) I'm trying to get running. Compression is good. The carb and fuel system might need a bit of a clean But that's not what worries me. I put some petrol directly into the carb, pulled the recoil and it still wouldn't fire. The plug was wet so it was getting into the cylinder. I changed the plug but no joy. I held he HT lead just away from the tip of the plug while pulling on the rope and there was no spark.
I took off the cowl and the little inspection plate on the flywheel. It has a points system like the one in the picture below. The problem seems to be the arm the points are on is very stiff. I have to use a screwdriver to prise them apart and when I do they stay stuck open, rather than springing back shut. The little leaf spring on the arm looks intact. I've tried spraying WD40 on it and working itback and forth but it's still tight. Could this be my problem?
Something else that I found was that there is nothing attached to the back of the On/Off switch. I assume there should be a wire of some sort? Could you tell me where this connects to, as I'd like to return it to original spec. I know the mower ran like this but that was over 20 years ago. Thanks
