Lawn Boy 7268 78

Bought this mower in 1980 the best running machine i ever owned. Unfortunately I am having a problem. it doesn't have a primer ball and to start it i use a little starting fluid. Never had a problem until a month or so ago it would rev high rpm's when started and then go back to idle speed. I check the light speed switch and it is on fast speed. I retired it from cutting grass, but i do use it to vacuum up grass clippings I hate to sweep.

Thanks for any help
