Didn’t start very quickly did it? Although it never does when it’s not been started for more than a couple of weeks. When it started, it was on less than all of the cylinders, this did improve once it had warmed up a little. This could be related to HT leads or similar. I have not looked at the rotor arm in ages. I think I’ll have look at the ignition system at some point in an effort to stop that from happening. I went out for a spin to the tip and then came a random route home partly due to crash on my route home. Here is a picture of the queue of traffic that I turned back from joining.
