( I cleaned the injectors by running Seafoam through the vacuum lines to the injectors).
You cannot clean injectors through the vacuum lines, cleaner has to be pumped through them under pressure.
You are correct sir. I was under the impression that the vacuum check lines provided air to the injectors for a better atomization (Too old of a system for that).
Seems to run worse with increased oil temperatures/higher overall engine temps. (Operating temp).
I got rid of my alluminum wings and picked up a Goldwing. Here to be a Light.
