Thanks for the replies.
Our irrigation water comes from McPhee, Colorado's "second largest reservoir". That concept is rather funny as the lake is not even 10 miles long and only a couple hundred yards wide. The water is cold; that's what keeps my trout alive all summer, and slows my bass growth rate.
I effect all sorts of chainsaw repairs and mods. One of the next "victims" is a big Jonsereds, a 90cc behemoth patiently waiting by the workbench. A side benefit of firing up loud, muffler modded saws outside my workshop is that it scares the pesky mallards and wigeon off the pond for a couple of hours.
