If the valves have to be done I'll have to bring it to a professional I'm not good at such things. Thank you for your help

Check valve clearance adjustment, especially if overhead valves. All of these type loose adjustment and severely disables the compression release on startup. Normal valve clearance is small and subjective to wear. Briggs and Kohler
