I’m chasing a lean condition. If I pull choke halfway out she runs good and can throttle it up no problem. If you take choke off and try to rev she hesitates bad. Temp is good. Has new fuel pump, rebuilt carb, fresh fuel filters. not sure what else it could be. I noticed these were open not sure if they are closing when warm. Definitely something to investigate. Didn’t notice any vacuum leaks gonna get into that alittle more too. Maybe I have air leaking in some where. It’s driving me crazy. Might try to crack a whiper vacuum line and put meter on it see what it’s pulling. When it off for while the whispers sag down soon as you start it they shoot right up so thinking my vacuum is good
