Choke adjustment on kohler cv224?

[The motor guy]

This engine is funny. Usually it's really easy to pull the pull cord and you have to be careful you don't pull the cord out too fast, because you'll hurt your shoulder. Then other times, it's harder to pull and it doesn't necessarily want to start. it's always started fine down to about 50 degrees, except today it was 38 and I couldn't pull it hard enough to get it to spin fast enough to turn over. Gave up, then tried again on the next yard and it started right up and was easy to pull. I tried adjusting the choke a while back, but didn't really see how it could be adjusted anymore. (I think that was it) I can't remember. I know it's got some type of easy pull start system, not sure if it's a spring loaded recoil or maybe it's a compression release on the camshaft that makes it easier. It's only got about 35hrs on it now, so I don't see how the valves could be out of adjustment. This is the first time I actually wasn't able to start it. Usually if it's hard to pull the recoil it just takes a couple more yanks on the rope and it starts. I also, don't like how these engines don't have a primer bulb. I bet it just needed to be primed, then couple that with cold weather and it was probably just flooded.

Don’t know if it can be adjusted. Could be hard to pull because oil too thick.

Young people don’t know what a choke is and its function.
I have a Troy Built Generator with a Briggs Engine. . During last hurricane, started leaking fuel from fuel bowl. Had neighbors look at it. These young guys are good with modern engines with Fuel Injection but know nothing about Carburetors, Float Bowls, needle valves, jets and Chokes and what a choke does.

Took generator to mower shop. They installed carburetor rebuild kit that included needle that controls float level, causing fuel leaking.

Good luck finding your pull problem

The choke doesn't affect the ease of pulling the starter. That is compression release.

You know I was thinking about this earlier that it seems anything below 50 degrees, it's just harder to get the engine to turn over fast enough to fire. This one is pull start, but even my electric start mowers have to crank for like 5 seconds before starting, where on a warmer day I'll just blip the starter and they start

What weight oil is in it? At 38f you are better off with a 5w bottom number. I couldn't recoil start a 10hp generator at 0f with a 5w oil, lifted it off the ground with the recoil with not enough spin over, 0-30w cured that.
At 50f fuel vaporizes faster than at lower temps so it's easier starting. I'm starting motors at 0f and with E starters it takes some cranking to get fuel up into the cylinder to fire up. Exception is the Tecumseh's with the primer, way faster start. BS on a rider with plow takes some extra cranking but it fires. Manual choke on it.

10w30 kohler semi synthetic. What's funny is after a few pulls it starts getting easier even though it hasn't started yet. It did the same thing the other day and I just gave it once big long fast pull ALL the way out and it started that time. The other day when I was having trouble I think it was still on the trailer, which is usually when I always start it, but I think I wasn't pulling it out as far on the trailer so don't hit my hand against the side of the trailer. The summertime I don't have to pull it as far out

They call for 20w50 in a lot of these machines now. Of course they have such a large temperature range that you can use each particular oi weight. I think even a 20w50 they consider good down to 20 degrees which is too low imo. I'm in Texas though, so it's pretty uncommon except for Janaury to get too far below 50 degrees. Typically if it's 45 or below, I just don't go to work and the mowers stay in the garage. lol Also, on days it does hit 40 or below, typically it's up to 50 by the time I actually get out to the jobsite.
