I try the bike again after my first post and it was going fine.. so i rev it up and the left side started to cut and backfire.. i let it idle some time and try puting some chock and it was changing a bit but after some more idling the right side stop firering! I remove the carb and reed valve.
Is it normal that the metal part of the reedvalve have a greenish coating or it is varnish? .
I dinth use it a lost in the last year ..
anyway i cleened the reed valve and will do the carb tomorow!
