Well, it's been a few months with of boat trips. Probably about 6 trips. Extra throttle warm or cold doesn't make much difference with warm starts. It cold starts flawlessly. Pump the fuel bulb, push the throttle forward, push in the choke, a few seconds later it starts and runs. The idle screws are set to 3/4 turns out. Once when it was early in the morning out on the water between 50 and 60 it started nicely but as soon as it got towards 70 outside it started to give me trouble starting it. Even throttling up didn't help much. IT would eventually start. Seems very strange to me. There must be something causing it to run rich. The most likely cause is leaking float bowl inlet needles but they both seem good and have been replaced. It runs flawlessly after starting and zips right up to max rpms. Also I am getting 3 mpg with 6 grown ups in the boat. I know because I can physically measure how much fuel I used on some recent joy rides. 7 gallons to go 22 miles @ 4000 rpms.
