Thanks professor. That shows me the where and what but I'm still concerned with how. Doesn't one need to pull the start rope to turn the engine to a set point like TDC (top dead center)? If so, how do I know where TDC is? Sorry for all the confusion and questions but I'm at about 70 to 80 hours now and feel I might want to check my valve clearance soon to possibly help prevent any future problems.
I looked it up this morning.
Intake is .005 - .007 in.
Exhaust is .007 to .009 in.
Both are with engine COLD.
Use a flat feeler gauge to measure rocker to valve stem clearance.
Yes, settings are made at TDC. I have a tool that goes in the spark plug hole with a moveable plastic rod in the center. As the piston comes up, it pushes the rod up. Maximum extension of the rod is TDC. Of course, you need to be sure the TDC found using this tool is on the compression stroke and not exhaust, meaning BOTH valves should be closed. This will be indicated by rocker clearance on both the intake and exhaust valves. I picked the tool up up years ago when my boys were into go carts.
Some folks use a paper or plastic drinking straw in the spark plug hole as a TDC indicator. Others inject light oil (WD40, kerosene, etc.) into the cylinder as it starts to reach TDC. When all the oil that can be pushed out occurs and it starts to suck back in again you have TDC.
Perhaps the simplest way to find TDC is to remove the spark plug and place a finger over the plug hole. Rotate the engine until you feel pressure start to build, continue slowly until suction occurs and then back up a hair to TDC.
BTW, on a generator without access to the crankshaft end it is easier if you remove the recoil starter shroud so that you may hand turn the flywheel. The recoil starter rope method can be less precise.
I don't claim to be a small engine mechanic. Someone with more experience may have a better method to share.
Again, 100 hours seems to be the magic number for adjustment. New engines should probably be checked at the 50 hr. interval.
On another note, the CPE part numbers I show for the forged rocker assembly is ST168F-1040100 (2007). The pivot bolt is ST168F-1040027 (C465). CPE will need to quote you the price if you decide to upgrade a 2006 or older engine. 1-877-338-0999 is the number.
