I have a full set of old Craftsman screwdrivers that I probably bought in the 70s when I was working my way through school as a Sears Automotive Tech. The part number on my screwdriver is a little different, 41584 WF. They have been great and I still use them occasionally. One flat and one...

I read somewhere a paradoxical concept about this topic. It goes something like this. The fact that this is happening is good for our society at this point in time, and paradoxically it will ultimately become far less of a distraction. For many, beliefs long held "close to the vest" are now in...

I'm living in Phoenix and look at what the sun did to my face. I suggesting you store your 5W-30 motor oil in my climate controlled work room. I can also check to see if Mobil 1 Extended Performance is still OK by putting some in one of my 4Runners.

My career was gas turbine heat transfer cooling of disks, blades, vanes and more. I also wrote software to perform the analysis. Retired ~10 years ago and started my career using punch cards saved in large boxes. Cooled airfoils had the greatest impact on gas turbine development cost and time...

Electrical Connector Pliers and a SteelSeries QcK Mouse Pad (gaming quality with excellent tracking and stability).

I initially bought a BR600 to move pine needles which requires air velocity. I also bought an optional add-on nozzle that increases exit velocity and turns exit air direction 45 degrees so that air skims over rather than blasting directly into landscape rock. The tube is at maximum extension so...

I run my BR600 at full throttle and lock it there to operate at optimal combustion temperature and not form carbon deposits. On start up, I'll let it idle for 20-30 seconds, then gradually accelerate to full throttle and set the lock. On shutdown, I release the lock, deaccelerate slowly to idle...

I use Honda HP2 at 40:1 mixed with 91 octane E10 fuel (10% ethanol) in a Stihl BR600 (4-mix engine) for yard cleanup every weekend over the last 12 years (about 600 total hours run time). I have had no issues.

Avg age 8 years, avg miles ~72,000. Accumulation of miles has slowed down over the past 2 years, with an average of 7000 miles/year on a 2023 and 1200/year on a 2011. The average time I have owned any vehicle is about 20 years.

My mother-in-law was about to toss a perfectly good Snapper lawn mower. I asked to have it, drained the fuel, oil, removed the wheels and took apart the handle. Everything fit very well in a box and there was no extra fee for weight or size as checked baggage on a return flight. This was in the...

It's how I feel when I wake up in the morning. I took the photo.

Topics in this video include... 1) Benefits of a fine nanofiber layer for surface filtering on the outside of an air filter. 2) Efficiency testing process and development of Donaldson Blue Media. 3) A severe duty case study in coal mining extended engine replacement from 30,000 to 50,000 hours...

Check the cabin air filter too. I suggest once a year in normal conditions and every six months in dusty conditions. My 4Runner cabin air filters last about 18-24 months with one vehicle in a carport and the other not.
