I'd make sure the basics are covered, newer plug, fresh gas. You can usually get an upgraded plug like iridium or similar by cross referencing the original type. One can also use a bit of starting fluid in the intake with a machine that's hard to start. It may not be an everyday approved method, but really helps lighting off.

Could be lots of things...

You have to start with the basics to narrow things down. Start with gas, compression, and spark.

A sled with low compression will be a bear to start. Both cylinders should be within 5 to 10% of each other. Compression is the easiest thing to check. If that checks out move onto fuel. Bad gas?

Once your sled is running does she run good, or stutter and hesitate a bit? Try some fresh fuel and a full can Sea Foam. You could have moisture in your fuel, or dirty injectors. Sea Foam should help either of these. How is your fuel pressure, may have an issue with your regulator - pretty common problem.

That is a battery-less EFI. Rail pressure, compression, TPS and voltage to and from the ECM need to be checked. Get your hands on the shop manual and go through the trouble-shooting progression and specs. Once tuned they are a good machine.

Sounds like a carb issue. Probably could use a good cleaning
