Stop in for a cup of coffee
I am thinking carb, just seems like it. Still have to adjust the secondary linkage, forgot to do the top of the secondary cover also, just remembered it last night. If the floats are ok might go one size jet/rod in the primary side smaller. Secondary's seem pretty good after the bog. Could also be the accelerator pump nozzles are to big, they are easy to change and have all the sizes also. I will get it figured out soon I hope when I get a few hours, doing 8 things at once lately here.
Other than that seems pretty good mechanically!
