The Jag has always been a bit more difficult to start vs. the Puma...despite the same general engine; (Puma being about 100cc smaller).
I feel like it's starting a bit rich. Back in the early winter, I noticed the plugs were wet when I started the machine...even with the choke off. I adjusted the choke (enricher) to spec and it seemed to solve the problem. However, it's still an issue. I fired the machines up for a mid summer warmup a few weeks ago. The Puma started pretty easily despite not running for months. The Jag took a lot of pulls. It was getting fuel to the carb; no issues there.
The fuel systems is new in both sleds: all lines, pumps rebuilt with kits and new impulse lines. Carbs are rebuilt once a season.
Can the enrichment plunger go bad? Do they wear out? Maybe try dropping it down further as an adjustment? Are there any hidden o-rings in there?
