So I've done alot of reading on this forum and I haven't come up with any good answers as to why, when going around 25 mph I get a hard cut in motor power. The engine will spool up to what feels like almost full power then cut, lower rpm and then throttle back up and cut again. At half throttle it will run perfect, and it idles fine. I checked the petcock and it flows fine. A few of my concerns are, I put premix into the gas tank but I still think the auto mixer might still be mixing more into the carb, maybe that's whats creating the issue. The auto choke hoses don't seem to be connected properly, and when I put them in the right place it runs worse
