I have a brand new 9.8 4-stroke Tohatsu that is extremely hard to start. First time took over 30 minutes of pulling, checking fuel, oil, plugs, kill switch, & repulling. (New motor has new gas, new oil, new plugs) Finally got it to run, did the 10 minute idling for new engine break-in. Tried again today, and it would not start, did not even try to fire. Finally after much pulling, checking all things again, got it started by advancing throttle past the start and restart lines and up to about a quarter-throttle level. It still took about 6-8 pulls with that.
Experience with other new motors is that they should start easily with one or two pulls.
Contacted 5 dealers in my area and all have 2-4 week backlog, so looking for ideas before taking to a dealer. Anyone have any ideas of a simple adjustment that won't void the warranty?
