"Greetings,
I have a 2008 Tohatsu 4HP 4stroke that I bought brand new. It has the integral tank and that is the only tank I use. Haven't tried external yet.
The motor seems to run well high idle to top range. However I use this motor for trolling exclusively and the low idle is poor. At low idle, the motor surges up and down, I would estimate 200-300rpm. It is quite annoying and elusive to what may be causing it. I have tried the idle adjust screw to find a sweet spot but doesn't help. Checked the fuel cap vent, lines, and fuel. I haven't tried an external tank yet, will do that next. The idle surge is quite regular. It's disapponinting since this engine is brand new but will keep trying to solve the problem.
I checked the archive here and didn't see a similar problem so was hoping for any additional advice before I dig in. Thanks."
