I have a Coleman Powermate generator with a Tecumseh HM-100 engine. The dipstick is on the upper threaded oil plug.
If you screw the dipstick in all the way, and then unscrew it to read it you will get a different reading compared to just placing the same dipstick in the hole and removing it. The difference is about as much as the low to high oil levels on the dipstick.
So the question is should you screw the dipstick in all the way and then unscrew it to get the reading of how high the oil level is, or should you simply place the dipstick in the hole without screwing it in, to get the reading of the oil level?
I looked in my Tecumseh manual but it does not give that detail.
Please include any reference from any manual you have regarding which way is the proper way to take this oil level measurement.
Thanks in advance for any reply.
