First time engine build won't fire

What are you doing to get on the compression stroke?

I don't set valves with a chart, I use EOIC which means......

Bump the engine until the EXHAUST just OPENS and set that intake

Bump the engine until the INTAKE opens and nearly goes CLOSED and adjust that exhaust

===========================

There are two ways to get on the compression stroke. Pull no1 plug, stick your finger in, and bump the engine until compression blows your finger out. Stop!! Look for the timing marks which should be "coming up." Then wrench the engine until the marks are "where you want" timing.

Second method has a caveat. If you have either valve cover off, rotate engine to TDC and look at either no1 or no6 valves. One set will be both closed, the other set will be both some open, on "split overlap." The two that are closed are compression stroke

The caveat is this is easy to mistake. When you get "let's say" looking at no1, on TDC, and you think they are closed, wrench the engine say, 20 degrees each way from TDC. If the valves move, they are split overlap. If they do not move you are on compression stroke
