Well, Thank you all for your suggestions, I will get to it this weekend and report back, The timing suggestion is a challenge, drove me mad trying to get it right when I restored it, got quiote confused about wether the timing should include the “Impulse Starter” spring or not! so that probably does need a look, and YES it does run HOT!, I will clean out the carb and have a look at that as well, the suggestion from stuart regarding the tines is a new one on me, Is it possible to fit them wrong?.. In the meantime… Back to the Merry Tiller!…
On a different subject.. Took my grandson Go Carting, Noticed that all the machines that rip round the track flat out all day have Honda GX engines, asked the chap if he had tried any of the “Chonda” Chinese copies, He laughed and said he had, and they had fallen to bits! had to replace with original Honda engines.. Tell us something I suppose. Night All.. Plonker
