Timing

Abodee,

Yup I think I will do the fuel pump removal to inspect first. I took a look at the manual and it says 3/16 movement on the cam without the crank moving is time for a chain replacement. So after some math I know that on the damper, 10 degrees equals 16mm. Damper is 7.25 diameter. X 25.4 to convert to metric. X 3.1416 for diameter / by 36 = 16.07 mm. So cam is half travel as compared to crank, so 3/16 = 3/8 on the crank. 3/8 = .375 X 25.4 = 9.525 mm. So since I am seeing almost 10 degrees of crank movement before I see diss move, I am thinking that chain is suspect. 9.525 / 16.07 = .592 X 10 = nearly 6 degrees on the crank. So if 6 degrees on the crank is not OK, then 10 degrees sure is an issue.
