122 Oil? Change & Plug Fix
My son and I are slowly going through the mechanical of our 122. Today it was time to change the oil, but the PO had pretty much stripped the hex, i assume 9/16", almost completely off. I had to use locking pliers to remove it. Being a machinist, I simply cut it down to 1/2" hex. It mostly cleaned up. Now an easily serviceable part. I even added a neodymium magnet. SAE 30 for those that want to know. However, being in Phoenix, does anyone have thoughts on 20W-50 in the summer (100+ degrees) months?
