If you dont have a dizzy then you need to turn the pump with a drill in reverse or a ratchet to build oil pressure..The dizzy is what powers the pump.

Correct...you dizzy has a shaft that goes from it to the pump to drive it...You can take an extension and use like a 1/4" allen and turn the pump....Chuck that bad boy up and it'll prime just fine...
makes sure you use reverse....forward wont work...

Andy's got you covered. You want to get oil throughout the engine instead of making a dry start.

I thought you didnt have a dizzy....thats why I mentioned priming that way..if you do it with the dizzy out...then you need not do anything other than the prime as mentioned above..stab the dizzy in and you good to fire things off.

I would take a VC off and verify both valves are closed on #1...

then verify the HB is at 0...if so

set the dizzy in....making sure the rotor is under # 1 on the cap when its seated in...

once running the pull the spout and set it to 10...drive it a tad and go up from there..

Just in case it wasn't explicit, you need to get oil throughout the engine before you ever hit the starter. Not only does this get the oil circulated before the engine starts rotating but it ensures you can build pressure. Otherwise it takes a few seconds with an empty filter and a dry motor to even register pressure. What happens if there's an issue and the pump cavitates or something? You'll have run that beautiful new motor with no oil pressure for 5-10 seconds.

It takes a few mins to prime it with a priming tool so I'd do it.



Good luck.
