Got a question for dht or whoever.
I just picked up a 27 ton unit second hand. It had only maybe a couple tanks of gas thru it. Anyway, I can't hardly get the 6.5 HP Kohler to start when it's below 20 degrees. This morning I stopped trying after 15-20 pulls. It was 10 degrees ambient.
The engine will occasionally fire, but getting it to run is another issue. I have not inspected the spark plug yet, but I doubt that's an issue since it ran well enough in warmer weather.
I'm thinking something isn't quite right with it.
The only gas that has been run in it is the non-oxygenated stuff.
Any ideas?
Sorry it has taken so long to get back to this.
I got a couple of spare carb main jets online. The Honda gx160/gx200 clone jets work in this carb. They are exactly the same as the OEM jet that Kohler supplies in this engine.
Anyway, my friend has a set of those tiny drill bits. I opened the jet from .028 (OEM) to where I stopped tinkering at .033 in .001 increments.
I noticed that at .031 the engine would miss (it seemed) very slightly. It became more pronounced at .032 and more yet at .033. I ran the engine for at least 20 min at a time, and I checked plug color every time. I found that the plug remained white for the most part until I hit .033, where it went sharply black (too rich).
There didn't seem to be much of an in between stage, such as what I was looking for where the plug turns a nice golden brown. But it could be that 20-30 mins of run time between stages was simply not enough to do that.
Here's the disappointing part. The engine didn't start any better in the cold with any of those main jet adjustments. I also had first gone thru the carb completely, making sure that every orifice was clear.
So, I took another jet, drilled it to .029, and called it good. I set a thermometer on top of the engine to more accurately monitor actuals temps on/in the splitter, and I more properly determined that the engine won't start at around 11-12 degrees. I barely got it to start at 12 degrees, but it will not start at 10 degrees. Between 15-20 degrees it is a one or two pull start.
I figure this must be just the way it is, and I will have to see if starting fluid aids in colder weather starts at all.
BTW, there is fresh 5w-30 synthetic in the engine. Another thought: I think that an electric start would get this thing rolling in colder temps, as it does pop and fire when I'm pulling it over, but just not enough to get it going.
I've decided to keep this splitter, and I had a welding shop extend the side rack out a few inches, and they put a one inch lip around it to keep pieces from falling off. I don't know about the other DHT splitter users on this board, but I find that bigger rounds are too much for the side table to handle. They slip off the rack. I like the rack and think it's well-made from the factory, but if others are like me in the way that I split wood, then the rack is a little too small too be really practical, and it needs a lip too.
The next project is to figure what to do with this hose (pictured). It extends down within a few inches of the ground and way too easily catches on stuff when the splitter is being pulled thru the woods. Almost tore it off once already.
Overall, I think this splitter is very well designed and built. I'm just looking for a little more user-friendliness out of it.
