Any ideas on going about “deep cleaning” the injection valves for the 70’? I was doing a volumetric test on gas for the injector valves and one was a little disappointing so I soaked it in gasoline but any other cleaning ideas incase?

I send mine to mr injector. He does a great job. Flow test before and after and new seals.

Very reasonable and worth every penny.
