Ok so i just realized i did not run my mower dry before winter.....i guess i had a brain fart when i put it away.....anyways it is a 15hp Kholer engine. Toro 36" wb. Should i go run it dry? I realize it has already been exposed to cold temps out in the shed, but is it a good idea to start it now? The temp today is about 30 degrees. Temps won't be steadily warm til probably mid march.
