Ok so I need some help. I've cleaned and rebuilt the engine. Mounted it. I replaced the points with a brand new ignition module.
I managed to get the mower started and it ran. Thought I'd done a good job. Let it run for a bit then stopped it. Tried starting it again and it wouldn't go.

Same for the past couple of days. Sometimes can't get it started, then it starts. I stop it, sometimes it's one pull start when it's warm others it won't go at all.

I've checked for spark, which I have. Checked the carb and it's getting fuel. Thought the throttle cable might have been playing up, but not the case. Has compression. I took the engine off and tightened up the crank case nuts more because I was getting a little bit of oil aroufnt the crank case seam.

Does anyone have any other suggestions?? I was hoping to get it to be a one pull start.
