February 6, 201115 yr hello all. my mates scorpa 04 250 starts with the choke on but stops as soon as you switch the choke off, it will only run with it on, and dose any one know what the air srew setting should be, 1and half turns out or 2 turns, any help much appriciated.
February 6, 201115 yr I agree, definately blocked jets. Remove the float bowl and go to someone with compressed air and put an air line through. Holes are so small you dont want to jam any wire in them.
