1985 force 50hp power loss

I've been working on this motor for a while and it seems to be problem after problem. Typical for force motor. I replaced the plugs and the ignition coils the motor starts right up idols great and run smoothly at low speeds. Problem is when I run the motor up at higher speeds I lose power. I can get more power when I hold the choke closed. seems like a carburetor issued to me fuel air mixture. But also thinking that my electric choke might be going bad. I'm looking for a quick fix maybe someone else has experienced these symptoms.

Figured it out. I had a damaged fuel line. Attwood has some fuel lines with a plastic shield on the inside and when pushed on to a fuel line connector the plastic crunches up and blocks the fuel. Watch out for these lines the plastic inner shield was also brittle and pieces of it would flake off easly.

To be more specific the line is the grey colored line. It has a plastic insert inside the line. Common issue with cheap line.
