I had explained to my dear :wife: how important it is for the tractor not to overheat and catch fire as the husband is useful around the house unburned. She agreed.

Nevertheless when the item arrived and the oldest asked what did daddy get she said "daddy got a new toy" :15: :rofl:so much for being taken seriously in this house :sigh:
You seemed to have got a good deal, if it comes up again, say a re-order request, get one for me.

Ok. Just finished cutting the grass with the Case 224. About 45 minutes of run time, engine rpm at 2750 or so. While cutting. Came back to the garage and tested temperature as soon as I got of the tractor. Running test, engine off test and engine oil. Now you know why you run them a bit for cool down.

Okay, never mind, seems their on sale again, not as good deal as yours, though.

My wife told me about some new thing, prime deals. This was like that. Now it's more, even if I reorder. If it goes on sale again I'll let you know.

Both plugs look good I’d say Eugen. Mine just a hair richer.

Looks ok if you are worried about it open the main jet screw 1/16 of a turn . It is really close . Air temp, humidity, and E in the fuel will all make minor changes in the colour .

Ordered a thermocouple thermometer from ebay a while ago and it finally arrived. I measured the temperature of the oil right after I turned the tractor off and it was 174F. At the same time the probe under the spark plug measured 313F. Quite a difference!

I will repeat the measurements a few times to get an average.

Your measurements and mine are a bit different Eugen. Be good to see what your average is.

I agree, plus I don't know how much to trust this thermometer. I'll test it with boiling water.
