Got a good idle, and great power throughout with nice trail of smoke. But after about 4-5 minutes, the temp starts slowly creeping up past 250. If I don't back off, it will keep on creeping up. The highest it got before I shut it down was about 285-290. I tried richening the high speed but I lost a bunch of throttle response. Air leak maybe? Kind of trying to figure this one out.
definitely sounds like an airleak to me , those carbs are not the best . seal it all up and see how it goes
