Check the ballast resistor - common failure.
I understand.5 BTDC is NOT good. That's not why it won't start, but set it to exactly 2.5 BTDC after you get it running. More and you'll destroy a 225 with knock under load.
Not at all accurate. I ran my slant sixes at 10 BTDC for many tens of thousands of miles with no ill effects. I had lighweight advance springs for even more advance. Five won't hurt at all. It sure won't prevent it from starting.5 BTDC is NOT good. That's not why it won't start, but set it to exactly 2.5 BTDC after you get it running. More and you'll destroy a 225 with knock under load.
75 psi is very bad. These engines run around 120 psi, so 75 will give it great difficulty starting, if at all. It may be that the valve lash was turned in way too far. That lowers the effective compression. Does it sort of 'sigh' when you are trying to start it and you stop cranking?1) What do the plugs look like now? Wet / Dry A, Both, can pump it up good enough to wet the plugs still no start.
2) Do you get a good spark? A, Yes
3) How much slack in the timing chain. (Use socket on front pulley nut back and forth. Slack portion is easy to move until chain slack is taken up and it tries to move the camshaft) (degrees of slack) A, pulled the cover and t/c is in excellent shape and on the money.
4) How fresh is the gas going into the engine? A, new
Ran compression check and it only has 75 lbs of compression?
I understand.
yes sir I have set a few set of valves on engines, enough to know about where they should be cold. thanks but I dont think thats it.I'm not sure what you mean by finger checked.
Valve lash is checked with a set of feeler gauges, with the valve cover off and the engine hot and idling. Since it won't run, you can set the lash a few thousandths higher to approximate the thermal expansion. This raises the effective compression and may allow it to start, if this is the issue.
Its definitely getting fuelI assume you full choked the engine in your testing. Jam the choke plate closed for a few engine cranking revolutions. I've had a few old engines not want to start no matter what I did. I full choked them and they lit off.
hot wired, all that is by passed.Check your bulk head connector for corrosion. On a vehicle that old, it wouldn't surprise me if every connector has the dreaded green corrosion on it.
