Hi everyone i have a Honda GX 160 and i was wondering how much clearence the rocker arms should have between the valves. I wan't to check them because it is making a fair bit of ticking. It sounds like a sewing machine. Thanks for the help.

The valve clearance should be,

Intake 0.15 +or- 0.02 mm

Exhaust 0.20 +or- 0.02mm

Depending on how old the motor is and how much you use it it may also need new valve springs.

Hope that helps

thanks hasady93 for the help much apreciated
