ARC Posted December 20, 2021 Share Posted December 20, 2021 Hi Guys , Any ST guru's out there . Picked up a ST90 (Ringed) and fitting out in a model. Following tons of advise about spray bar angle and tank height but curious about the barrel when closed . There looks like a cats eye shape to the left of the barrel that's open even when the barrel is shut off ? Is this normal? thanks Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted December 20, 2021 Share Posted December 20, 2021 Still same answer, there could be a burr on the barrell caused by the screw, strip it and look. Quote Link to comment Share on other sites More sharing options...
