Ok. I'll play around with the choke more then. It does shut and open 1/4 inch when the engine starts and slowly opens till warm. Maybe I need to set it to open slower. I'll try adjusting it more. My van is an 82 and definitely has hydraulic valvetrain. I had to replace the valve cover gasket so i got a look at that. Ill be taking the valve cover off again to take a look at how the mmo in the oil has been at cleaning some of it up. It wasn't horrible just some build up from 36 years of use. I'll take the numbers off the carb later. Been raining here. Hopefully spring will come soon.
