I've got a gas 3020, front console. It starts and runs fine in the summer (sounds like it cranks slow to me, some others agree, others say that it cranks as a gas 3020 should).
A couple of locals have suggested "improvements" and I'm wondering if any are worthwhile. It's already negative ground, but still has the generator, which works OK but barely (if that) keeps up with the lights. It is a yard tractor, probably used 2 hours at a time max in the winter. Sometimes I mow with it in the summer, but also use it for short terms just to fill a pickup with the loader.
It already has the electronic ignition and a Zenith carb (upgrades I've made). It has a tank heater, and I plan to plug it in before starting in the winter. I do understand how the manifold heat blocks work.
Some have suggested that I put in the next size up starter. I believe the one for the propane 3020. I'm told it will fit, and will not extend the solenoid (which is already almost touching the carb) but that the starter body will be under the carb so that the starter will need to come off to remove the carb. This sounds like a problem I don't want, and I hate to replace a working starter, but I also want a reliable tractor.
Others locally, and posts I've read from Gerald J on here, recommend switching to an alternator. As I said, the generator does work, but the tractor is used for lots of short "trips". Is this something I should consider?
