OK being extra cautious I mounted the saito inverted on a stand now when i got this engine it was used and i had problems with it (mounted sideways) but tracked the problems down one by one first the valve lash was out of tolerance two o-rings were bad and the brand new fuel tank it was feeding from was bad (nitro models grrrrr never again). But now it will be mounted on a powerline edge 540, first test on the stand amazed me, idle was perfect no adjustment to fuel started easily and ran great maybe inverted is the answer either way I have a renewed faith in this engine and again thanks all for the help.
