The loopers sufocate if trimmed too low and the problem is amplified by a cold running motor. In my fairnly limited experience working on these ’92-thru motors, the newer you get the worst the issue. The 40-50hp motors tolerate it better, the 3-cylinder 60-70hp motors not so much.
The pre ’89 motors had fixed jet carbs that just seem to be so simple and good running. Post ’88 things just get more ridiculous the ‘newer’ you get.
