can you change the prime ball on a mower?

Never heard of a Tocoma engine brand- it could be Tecumseh. If so, the primer bulbs are available seperately and are therefore replaceable. A Tecumseh agent will need the engine model and code before he will be able to ascertain which bulb to supply, so if you can't find your numbers because of the paint then take the whole mower with you and he should be able to find them for you.
