i am rapidly learning in life that most tasks run smoothly when i make measurements before the task, no more so in engine rebuilding.
I am looking to measure 2 things...
1. TDC, is there a dial type guage available that will screw into the spark plug hole, so i can set TDC for timing purposes without taking the head off?
2. Bore measurements. I found this old thread here http://dirtrider.net/forums3/showthread.php?threadid=65220&perpage=20&display=&pagenumber=2
Rich described a "Fowler Bore Guage" and if anyone knows an online source please let me know, sounds like tehy are around $100.
During my research, i also found a "telescopic guage set" like this

I am by no means a cheap ass, but i wonder if i can use such a guage to measure the cylinder bore with the help of my digital calipers? I know it sounds daft, but this could be a better way of measuring piston clearance since we are comparing 2 measuremetns from the same tool rather than relying on the measurements from 2 different tools being accurate However, i do apprieciate, that the precision of this method could be somewhat unreliable!
thanks
