I have a first Gen 83 so not same model as yours, but for me, especially first fire up in spring, it can be temperamental. This spring my front right was not firing, the exhaust temp was colder colder. I took plug out, obviously soaked with gas and fouled. I then reseated my plug wire in the boot, reassembled, and fired up and ran perfect. If you are pretty sure about getting gas (and pulling the plugs will confirm that because if they are getting gas and not firing, they will be wet and need cleaning) I would reset the boots. (I'm not sure about your Gen, but mine is a simple unscrew the boot assembly, clip 3/16" off spark plug wire tip, and reassemble).
