Greetings, As mentioned, the '66 200 idles fine, no missing, clean colorless exhaust, but tries to stall upon attempting to accelerate. The 1100 Autolite 1-V was recently "rebuilt." I can choke the barrel with my hand or by rotating the choke plate to almost closed and it will rev up as requested. Open the barrel and it gags as if it's run out of fuel. Leave it alone and it returns to smooth idle. We've disassembled the carb and found minor fine particles in the fuel bowl, cleaned and reassembled. The accelerator pump is newly rebuilt, once again, very fine particles (rust?) found in those ports as well as vacuum line to distributor, all thoroughly cleaned. Fuel to the bowl is perfect. Those fine particles aside, why will it run at idle but die upon asking for power? Thank you for your consideration.
