starboard engine starts right up, runs fine....port engine, takes a long time to start.....5 tries, 8 seconds per try....once it starts runs fine, goes up on plane fine, runs wide open fine...

but if I shut it down after running a while and try to restart, again takes a long time even when warm.....and after running for a while, if I go back to idle at the dock, the rpms are low and it will stall out....I can get it restarted, takes a while, when it first starts, seems to smoke, but after 20 seconds or so smokes no more than the other engine, which is very little...

some recent maintenance...
- using non ethanol gas
- replaced all fuel filters...one on engine, and racor
- replaced plugs, gapped properly
- cleaned o2 sensor...was not that fouled up on inspection
- check all plug wire grounds (but did not check spark or resistance yet)
- new poppit valve, spring etc.
- new thermostats

I use ring free...

any thoughts....
