1980 175 Merc V6 moved to Colorado 5500 ft elevation from the midwest 600 ft elevation.
Changed prop from 21 to 19 helped a bunch. It would stall out around 2000rpm
Changed plugs and new bulb.
Have not changed the jets yet.
Pulled front cover to look at carbs and they are clean.
Last weekend it started right away at the boat launch. Tied up to park the truck/trailer. Went to start it back up and then the drama started. Start and die. Rough idle and a couple die outs at low speed. Restarts pleased the crowd with a ton of smoke. Ran it at 2000 rpm for five minutes with no problems and then W.O.T with no problems. Turned it off for the kids to swim for an hour and she started right back up with no problems.
What can I do about the cold start problem?
