I have a single cylinder sachs motor in my Amphicat. I just rebuilt the carb. It will run great when you first start. I drove it around a while made a couple carb adjustments to the high because it wouldn't open up. I let it idle a few minutes the. Drove it more. The. It died an the motor was so flooded with gas that I had to pull the carb an pull it a few times to get the gas out. I let it sit a while an out the carb on. It still won't start this is the second time it's done this. Any ideas?
