Hi
i start up engine with the air level to position 1 (see foto) and engine runs ok at 2000 rpm...but
when i open the throttle and revs go up to 4rpm they stay there even if i close throttle....only if i turn
air level almost to position 2(if i turn total to position 2,engine stop) engine goes back to 2000rpm(i know that engine must run at 1000rpm idle speed but i found that problem first and thying to solve it).
Is my problem air leaks,throtle cables?
??or something else?
