I cant get my Yamaha 250 Timberwolf to run smoothly (Should have bought a Honda, I know ).
I have rebuilt the engine and replaced the jets in the carb but it will not idle when warm or run smoothly when not under load. It starts ok but does not like just bumbling along slowly on part throttle when out lamping. I'm guessing it is down to carb setting (Mikuni) but not sure what to alter. I was going to live with it but it was a right pain last night so does anyone have any ideas before I have another go at trying to sort it out?
