Just picked up an old Glastron (1971) with a VP AQ130A (don,t know the history) got it cleaned up and started but it won't run. If I pump gas in through the primer nozzles by working the throttle lever it will run for a while until it floods out, or will just stall if I quit pumping. I pulled the carbs (Solex 44pai) and cleaned them and blew them out good and put them back without any improvement. I concidered it may be a fuel pump problem but the float bowls are filling up ok so I'm shying from that therory. It does backfire a bit so I'm thinking maybe the valves might need ajusting and there may not be enough vacume to pull the fuel in????
