Hi folks, this is the engine I have purchased to pop onto the edger frame to give back to the relos.

It starts and runs very well but .............. it hunts a little in the mid range. I have tried the mixture screw as Grumpy has advised me before on the 12HP I wrote about earlier. Whilst that motor did it at idle and seemed to run better elsewhere this 3.5 does it in the midrange.

Seeing the relo runs it close to full throtte during use I'm not too concerned but how do you iron it out of the mid? I had a good play with the screw and it did improve but not eliminate the issue.

This is the motor;
