There is no guarantee that "tightening" the secondary air valve will stop the bog. BUUUUUUUUUUUT, this is a very likely cause of your bog. I would recommend tightening the spring tension a little at a time, drive, repeat. If the spring tension on the secondary air valve is too loose, then this is very possibly the cause of the bog.
