OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Honda Engines Honda GXV160 giving slight dark smoke puff when revving?

I have had issues with some of these Hondas for some reason with the choke not coming off and I have had to put a small spring on them to ensure the choke fully opens. And then with these vise versa, you have to ensure the choke fully closes or they will not start. Sometimes they can be a fine balancing act to get right

Yeah no choke issues for this one super easy to start right from the first day I had it.

Unsure what the next thing to try is? Smoke has definitely gotten worse from when first noted on here.

I have it running 'better' now.....Red Line SI-1 fuel cleaner (recommended by Tyler) arrived. I will start using.

Wondering if it's worth trying to remove some of the carbon build up that seems to be in the cylinder & piston head? A mechanical disassembly would seem a tad much - but I've read spraying carb cleaner down sparkplug hole, allowing to soak can loosen and assist removing it.

Any thoughts on if it's worth removing the carbon & if so how to do welcomed. :-)
