Another grass cutting with the 224 and gadget. Outside air temp 75F. Oil temp in tractor 70F, before start up. All grass blown off. Oil temp was 125F at the end of grass cutting. Was down to 113F by time I let her run around 1800 rpm while I was blowing the grass off. So then when I shut off the engine, I thought I’d turn the gadget back on a see if the oil temp would rise from thermal heat with out the cooling system on. And it did not rise, it kept dropping. So that’s good.
I figure now that I have a idea what it’s going to run at, on an average day. If it got over 140F I’d start looking for a problem. Thanks for reading, this will be the last post from me on my findings. I don’t think things will change much now. I might post once this winter when I’m throwing you know what, to see what the temps are. Just for the heck of it.
Have a good day gentlemen.

Noel, thank you for doing this! Where is the temperature probe located?
Last time I used the 644 I used an infrared thermometer and the temperature of the engine on the side of the carburetor was 97C. Either that thermometer is bad or the engine overheats or both.

It’s located on the steel line for the fluid going to the cooler. Front right side Eugen.
Did you check your timing yet on that engine ?

Hope you don't mind guys, I have moved the posts the latests posts specifically about the engine temperature to a new topic
viewtopic.php?f=4&t=888
I have a 444 that's running really well and I use at the moment just for mowing, that never overheats. I will check the temperature on it with the IR thermometer on the head, right around the spark plug so we can use that as a base line. There's a digital thermometer with a k-type thermocouple hidden somewhere among all my junk, when I find it I'll install the thermocouple right next to the spark plug and get some more precise readings.
Hopefully we get all kind of data on the K-series engine. If there's interest this could be done on the other engines too, like the Onan 16HP.

As much as I like the multi-function gauge idea, kinda like lots of gauges.

Normally those types of boats have very nice eye candy in them.

Then you'll like what I've done to my old 442...
