Adjustable timing pointer

To check the adjustmnet of an adjustable timing pointer the way I understand it using a piston stop you mark the balancer where the piston hits the stop and then go back the other way to the stop and mark that on the balancer and then split the difference right? How do you guys find the middle of those two marks ie; tape measure?

You can use a tape measure or a degree wheel.

easiest I'v found is to put your stop in the plug hole then adjust it as close as you can to stopping at exactly tdc.....then the marks will be 1/8-1/4 apart...then just eyeball from there

Works for me thanks. It shouldnt be off but its a mud racing engine and the timing pointer does a real good job of scraping the mud off of the balancer and just thought I should check it!

You usually have to worry more about the balancer spinning than the pointer bending.

Ran into something minor...when turning the engine backwards how do you keep the balancer bolt from backing out? I pulled all of the plugs but the stop I made must be catching some compression in #1 because the balancer bolt lossens up at a certain point before it gets back to the stop.Compression on this engine is pretty high.

Go to Harbor Freight tools and get a flywheel turning tool, cheap $5-$10. Don't use the balancer bolt to turn the engine.
