Hi MGW, and welcome to ODK.
I'm guessing (without seeing any pics) that you are correct, Straighten the tab if needed and then pull it outwards to apply more tension to the spring; not too much though, 4-5mm initially and then adjust according to revs. The 190cc quantum engines should rev at about 2900-3000rpm at full throttle.
