Good to hear you're doing well. I really enjoy reading up on your progress and what you face and how to handle it. I have a small side business and am learning along the way. I do face similar situations as you so it's nice to know it's just not me.
I to have a list of people I just wont work...
Currently a 2011 F250 work truck. Before that was my 02 7.3 pickup. Before that for 9 years it was my 02 7.3 service truck. Service truck has 475K miles. For a couple years I was putting 1200 miles a week on it. Its semi retired and gets driven about 2K miles a year.
I have a sanitaire bag vacuum. It has balls and performs better than the canister style vacuums. Only maintenance is change the bag when full and change the belt every 2 years.
2 motorcycles were laying down in the South bound lanes down from the springs and going North there was some running event that had a cop going the speed of the runner in the lane this morning. Backup of cars both directions and when the cop pulled over into the turn lane to let everyone pass...
We had one at the family business and I was glad when it got sold. Be prepared to have the doors get ripped off the first time it goes to the landfill...
I noticed that after you pointed it out about only 1 valve stuck. I'm curious as to what caused the push rods to bend. More curious to know how 2 got really bent. Seems the only way to really bend pushrods is to have stuck valves but you only have 1 that is stuck.
Old ethanol fuel will cause intake valves to get stuck. When the gas gets old it gets sticky and will cause intake valves to get stuck. Enough to bend pushrods.
I ran 853 and 863 for years. The 853 has servo controls and is so smooth. 863 is a beast for its time. Also have a 553, it has it's purpose. It's really only good for moving wheel barrow amounts of material. They don't dig well or do anything else well. At a minimum I would not get anything...
Ca handgun roster only applies to NEW handgun sales. That's why used guns in Ca don't have to be on the roster to be sold, they are not new.
Whatever you do, if you buy a gun in Az and bring it into Ca, make sure its Ca compliant based on assault weapon "features". Roster doesn't apply here...
