Thanks grumpy,

I'm getting a good continuous spark. I've previously emptied, cleaned and checked the tank and filter and all is good there. The governor mechanism all appears fine to my eye. The anti-oscillation spring seems to be moving freely and extends properly when manually moving the governor arm.

Now, adjusting the governor? Do I just use my ear to set the engine speed? I don't have anything else to measure it at the 3100rpm. I hope this isn't a stupid question!!!!

Thanks for taking an interest in this.
