    I have 2 Toro blowers. Both starting to act up. I want to check compression and valve clearance but cant figure out engine it is to find the specs. One is a 721r 38451. The other a 621r 38741.

    So i found out its a toro engine. My compression im getting is roughly 45 to 48psi. And i found the literatures for the valve adjustment.
