Thanks Charles I appreciate that!

I like "dials" because there batteries do not go dead.

[@robbinsracing801]

Can't argue with that. I would definitely agree I hate when the batteries die.

[@timdouglass2519]

Is it possible to have a competitive lo206 that is not built by an engine builder?

[@robbinsracing801]

1000% YES.

[@scotts24d]

Might have Cam lobe wear on that motor hows the oil been looking & do you have a Magnet on drain plug & sence this is a spec motor all cams by Briggs should be the same tallerances

[@robbinsracing801]

Yes the oil came out black. This was a customer engine. Could also try replacing the push rods before replacing a short block.

You really need to lock the engine down to your bench. If the engine is free to move around, it will effect your reading. Also make sure your engine is parallel to the gauge. A few degrees off square to the gauge will make a difference in your readings.

[@robbinsracing801]

Very true, so I have a dial indicator holder I use on 2 strokes and if I remove the head I can center it over the lifter and lock it down with one of the head bolts. Testing that way I get Intake .2525 and exhaust .254. I did complete cam profile measurements on my new 206 that way as well.
