bout 500 miles on the motor, started to start sluggish (wont start with choke). like symptoms of a dirty carb, so cleaned the carb real good, did find some debree in carb, blew out orifices. put back together, same issue. i have to pull with choke on ( wont fire), flip choke off & pull start giving gas and it stumbles to a start, after it warms up, it runs/ idles great....SO... i put in a new plug, a new magneto, fresh gas, and even changed out the old carb with a brand new one, still wont start in choke. i have even tuned the old & new carb starting at 2 turns out on the air screw(brass) and gone up to 3 turns. normally between 2 and 3 turns out works great for me. i can start it through the method i told above. and can ride it all day once i get it going, it runs well.lots of power! could the valves be causing this? pretty much the only thing i havent done.
your input is greatly appreciated.
thanks
