Just curious;

Has anyone tried finding TDC for valve adjustment using an endoscope to find TDC versus the straw or chopstick in the cylinder? Seems to me it might be a real easy way to find the right spot.
 
That kind of precision for valve adjustments is a bit extreme :) . Possibly if you're checking your
cam timing , maybe . The base circle of the cams extends on both sides of tdc . If you must , then
you should have a degree wheel which you can mount to the end of the crank , then with something
you can thread into the plug hole and extends far enough to stop the piston before tdc , you would
mark the position on the degree wheel . Rotate the crank back and up to tdc (the other way) and mark it .
The position between those marks it true tdc . Peter
 
I am not looking for precision, it just seems to me that it might be quicker and easier to find TDC, than watching a stick go up and down.

If using a bent stick was good enough for the Cave man who are you to say it needs to be improved upon !
You dang kids today always trying to make things better and more complicated... [ just kidding ;) ]

It’s not like we have Endoscopes just lying around the place... :rofl:

The Honda has the two access holes one to see the TDC mark and the other to put a wrench on the crank.
