Had tried other fuel like Tornado and O'donnel, just same result.
When I go slow, its ok. When I hit full throttle, same like the other case, it just go zzzzzzzzzzzzzz.....
Does any know the factory settings for all the needles? I guess I have to reset it all and start adjust it again.
Thanks a lot!
