Old TRX, new to ATV, new to forum

Howdy from rural Arizona. Just bought out first ATV, a very used 1988 TRX300 (2wd).
It had a broken axle, came with a new replacement. Got the axle in but some parts were missing. The nuts and lock nuts on either side of the diff/brake, hub nuts, lug nuts etc. Have replacements coming from Bike Bandit.
Engine turns but haven't started it yet. I'll address that once it's back on the ground.
Paid $500 for it so it will make for a interesting project.
Hoping to find helpful info on this forum.

All the axle parts arrived, well, need 6 more lug nuts.
So it's on the ground on its wheels.

Engine cranks. Carb getting fuel (and I have starting fluid).
What I'm missing is spark. Old plug was fouled, new plug no spark. Connections to coil and cdi look good.
So new coil and cdi box on order.
I did also clean the left handlebar switch.

Do you have 12 volts on both the black wire and the black wire with the white stripe at the CDI unit when the key and handlebar switch are in the on or run position?

Won't be home until next week to work on the TRX (I'm a truck driver).
But I had an idea (oh no. No no nonono).
I have two Yamaha XS1100 at home that run quite well. They are shaft-drive...

My 1988 TRX300 has only blue & pink, then black & red & red/brown.
No black/white.
I have battery voltage to the black with the key on. Stop/run doesn't matter.
And still no spark with new CDI and coil.

Sorry - my error - I was looking at a 98

You have 6 wires on the CDI unit - there is another box that looks like a CDI, but it is the alarm unit - the alarm unit has 5 wires, brown with a red stripe, black, dark green, pink and blue with a red stripe - the CDI has black with a yellow stripe, dark green (ground), blue with a yellow stripe, yellow with a white stripe, blue with a white stripe and green with a red stripe.

The black wire is hot when the key switch is on - it goes from the key switch to various places, but we are only concerned with ignition at this time - the black wire goes to the handlebar engine stop switch - when that switch is on, the black/white wire is hot - the b/w wire plugs into blue/wht wire that goes to the CDI box - do you have 12 volts on the blue/white wire? And does the dark green wire have continuity to ground?

Beyond this you will need a peak voltage tester to test the output of the pulse generator, the output voltage to the coil and the voltage to the spark plug.

Without a peak voltage tester, check the continuity of the pulse generator and the ignition coil - go through the connections cleaning and lubricating them with dielectric grease - check the continuity of the spark plug cap and always test using a new spark plug - be sure to verify good grounds at all points requiring ground - don't concern yourself with the alarm unit - it's only function is to turn the oil temperature light - the ignition will work without it.

Let me know where this get's you

It fires up, with starting fluid.
Very little fuel in the tank. Only flows on reserve.
I'll get more gas when we go into town.
Otherwise it's carb time.

FWIW, I do have experience with older vehicles.
Current motorcycles are a 1978 & 1980 Yamaha XS1100.
My transportation to/from work is a 1968 F100.
Work truck is a 2020 Volvo VNL670
