I'm at day 7 in Cincinnati off the grid - which is nothing to cry about

I have a 30 year old 3500 watt generator from Sears. So far, it's
working fine. But I've been reading some of the threads about inverter
generators (which I had never heard of) and I would like to get some
opinions. I pulled the battery from my Ford Explorer and I use it at
night along with this:

During the day I recharge the car battery using a separate 12V output on
the generator that provides up to 8 amps. Funny, I used to wonder why
the hell I would need this. Anyway, today I am going to have to run my
business desktop PC for a while. Would I be better off hooking the car
battery to the generator 12V to keep it charged, then also hooking up
the inverter and running the PC off of it? I realize that I have a
cheap inverter but would the power out of it be less likely to feed a
spike or low voltage to my PC than this tired old generator? Or maybe
just charge the battery for a few hours and then just use the battery
and the inverter and do my work quickly?

This is the best photo I've found so far of the generator and the guy
has the engine partially disassembled:

I would check voltage and cycle output on the gen, 3600 rpm is 120v -
60hz, go lower in V and cycles go lower, go higher than 120v and
cycles go higher. Adjust rpm with load used
Are the local big-boxes open? If so, go buy a cheap UPS unit, and put
that between your PC and your power, to clean it up at least a little.
This isn't a table saw- you are not only putting the PC at risk if a
power glitch happens, you are putting your data at risk, like if you
happen to be in the middle of a disk write when it all goes dark or
spikes. Laptops are better this way- they have some power filtering
built in. If the big-boxes are closed, inverter from battery, with no
running engine involved, is the safest. When picture starts flickering,
save your work and shut down. My agency has lost a lot of PCs and other
computer equipment, over in the sandbox, due to running them off dirty
generator power.
