Hi Bankone1,

Thank you for the donation.

Here are the procedures for adjusting the valve clearances.

Rotate engine until No. 1 piston TDC mark on front camshaft sprocket is aligned with mark on rear of front cover. See Fig. 2. Adjust cylinder No. 1 to proper specification as necessary. See VALVE
