this story been told before i'm sure, (engine new to me) idles good, push throttle and gets to 33-3500 rps then bogs, bump key in and zoom for a few seconds, then back to 3500
backround info - carbs rebuilt w/kits, have online manual, cam roller lined up with lower mark on cam(2 on cam), spark advance moving to stop when throttle advanced, did drop test at idle , rpm drops on all cylinders, get cheap china fuel pump would't pull fuel at idle had to keep pumping bulb every minute or two, back to old pump, think compression is 130, was when bought
next will compression check again, and check high speed jets( will remove drain screw and poke wire throw), looking for suggestions for next weekends work list.
