No kick starter, eh?
Putting gasoline on the spark plug won't help start the bike. Squirt some gas into the carb opening, then see if it fires.
Is the gas lever on reserve? Try it.
There's nothing older than a 20 year old Jap bike. Hell, that thing was old when it was one year old.
Look in the paper and spring $100 on a Jap bike that's only 5 years old.
If you really like your rice ranger it's time to spend money on a diagnostic. But they may not work on anything over 10 years old.
Good luck.

remember, you need three things for the bike to start: one, you need good fresh fuel. two, you need spark at the plugs. three, you need compression. If you have these three, the bike will start. It may not run great, but it will run. So, break it down. Do you have fresh fuel in the tank? is the fuel getting to the carb? is the fuel getting to the cylinders? If so,
Are you getting spark at the plugs? this is easiest tested by taking a spare plug ( leave the plugs you are using screwed into the cylinder(s) so that you don't get fuel pushed out of the cylinder causing a fire) take the plug wire off your sparkplug and put it on the spare plug. Ground the spare plug to the bike by placing it against the cylinder etc and try to start the bike. Watch the gap on the plug to see if there is a spark across it. If so, you have spark, if not, you found your problem. If you have spark then: you need to do a compression test on the cylinder(s) to see if you have a problem like a busted valve, broken rings etc. I'm sure that these three simple steps will tell you where your problem is.
Good luck

You need to proceed in a systematic manner to diagnose the problem.
Check to see if you are getting spark (if not, you need to do an electrical diagnosis).
Check fuel mixture. (If no fuel is getting to the inlet valves, then you have a problem in the fuel delivery somewhere --- clogged lines, clogged filter, gummed up or faulty carb.
Check cylinder compression (if you have poor compression, you may have valve, piston, rings, or head gasket problems).
You may also have timing problems or a stretched cam chain.
Get a service manual for your bike. The often have some troubleshooting procedures that will help find these problems.

If its been parked a long time the valves might be stuck open, also try spraying starting fluid in the carbs or plug holes.

"fuel pump" lol. Is there spark? If so, it'd be in the carburetor. A good rebuilt and cleaning could be in order.

Make sure the engine kill switch on the handlebars is set to RUN and not "stop."

check your compression...those bikes were bad for burning the valves

Maybe a fuel pressure problem, check the fuel pump.
