OK took out a 73 25hp 2 stroke that I picked up 2 weeks ago. New points/condensers, plugs,fuel line, carb was pretty clean when removed and inspected. Compression is at 100/102. Starts and runs on 1-2 pulls. Now here is the problem that I can't get. While using it this weekend it worked great most of the day. Then I gave it full throttle, it took of , kind of back fired/stalled. Started on one pull but then would only run in gear if the choke was on and then only at about half power. I pulled the plugs and both were dry and warm so i think both cylinders are firing. Tank is like new no rust with fresh gas and mix bought same day. Fuel line and bulb on the tank are new. Bulb was hard(full) when the stuttering happened, gas was about 1/4 full. Screen on the fuel pump clear. Made it back under half power to the dock. sat overnight. Started on two pulls next morning. Gave it full throttle and floated the choke back and forth and then it finally kind of just kicked in and took off. Ran it full throttle right back to the dock on the mainland (I was overnight on an Island). I like the engine and it ran great but I don't want to be stuck. Feels like it just wasn't getting enough gas under load. Any thoughts what to look for or check? Perplexed right now. Thanks.
