Re: Tohatsu troubles
We have a 2009 Tohatsu 9.8, with what sounds like the same issues. I had the carb rebuilt about 2 weeks ago, and it ran great until last Sunday. I ran it dry and started it again on Friday, and we are back to square one.
I had been leaving the fuel bowl full since it sat no more than a couple of days at a time, but Sunday I decided to run it dry. My very amateur thought is that when it is really warm (it has been in the 90's) that running it dry caused the problem, since the fuel evaporates much more quickly in the heat, leaving behind the varnishes and residue that wrecks fuel systems.
