Well, I finally got around to taking a couple of test rides with the
new radiator duct in place. It was about 95*F when I went for a 25
mile ride yesterday. The temperature didn't change much from my
earlier reported 196*F-202*F norm. In fact, it surprised me by
staying on 200*F most of the time. I'd expected a little drop but it
didn't happen. But the temperature did vary less. About the only
time it changed was when I stopped a couple of times and idled until
the temperature stabilized. For about 5 minutes, the temp would
slowly rise to 210*F, then stay there for another 5 minutes, when I
got tired of watching it and drove again. Then the temperature
dropped back to 200*F within 1/4 mile. A 15 mile ride today went just
the same.
It may be my imagination, but I seem to have less engine noise in the
cockpit. But I also THINK I have a wind noise that I didn't have
before. With my hearing (or lack thereof), it doesn't much matter.
Then, yesterday, I finally wrecked the HF 1/2" electric impact wrench.
I bought it 3-4 years, maybe more, ago, expecting it to last a year.
The blades needed changing on the ZTR mower. The 5/8" bolts holding
them would not budge. The Craftsman impact wrench didn't do ANY good.
The HF removed 2 of the 3, but the third, after 'way too much
hammering, caused the output shaft of the HF wrench to twist in two
inside the nose housing. I finally had to grip the pulley on the top
side and use a pull handle on the bolt to break it loose. Next stop:
HF for a new impact wrench.
