Cvlngineer..... I don't know if you received that yet. I'll scan and send it to your e-mail address.<br />---------<br /><br />Bowhuntr.... He's not speaking of a "camshaft", but rather the cam that rides against the throttle opening roller on the starboard side of the powerhead.

Joe,<br /><br />Thanks very much for the picture. That is the one that is on here, so I can, at least, rule that out.<br /><br />Thanks again,<br />cvlngineer

Joe,<br /><br />After looking more closely at the picture, I see a dimension given for the length of the rod that pushes the timing cam. It looks like it says the distance is 4.31/32" Does that mean 4 and 31/32 inches or 4.31 - 4.32 inches? <br /><br />I appreciate the help,<br />cvlngineer
