I changed all fuell lines bypassed selector blocked off one supply port . left the vent as factory contions I check the check valves etc I used after market filters I put two in line before carbs
this is a twin carb 717 motor .
motor only runs good with the choke plate half closed and it has to block the center of carb (the center being the about 3/4 inch round don't know the proper name if that part of carb)
the guy before me said he had a bog problem. so I rebuilt carbs with after market kits I used original spring inside carb for needle valves.
did find that the exhaust is leaking under the purple pipe and above the white manifold but that's only at high rpm. the bogging down is happening at mid throttle it wont rev up unless I close the choke halfway.
maybe I have two problems ?
I did do any adjustments to carbs like the needle valve arm is the only major adjustment I can think of
I will fix the exhaust leak first if possible.
I ran it yesterday and it runs with the coke half closed nice but I don't know the speed it seems slow but I'm used to my hydrostream venom that did 110 mph . it felt like 40 mph though
could the exhaust pipe be bad or just the gasket the guy before tried to fix it I believe . but he wasn't very handy and did lie to sell a lot lol
