Motor issues.

I bumped the timing to 14*. I also changed the piston springs in the carbs and those to settle down.
I'll be back next week to work on it. I'll mess with the timing some more and bump the lash to .022 or so.
I'm concerned as to why #3 Exhaust tube is 600* when the others are 300*
Once I get things figured out I'm having Ray on here setup a distributor for it.

It is not uncommon to have different header pipe temps its mostly caused by poor cylinder distribution of the intake manifold. In your case #3 is running a leaner AFR than the rest causing that header pipe to heat up. Read the #3 plug it will tell you the story.
Remind me what carb and intake are you using?
