best of all: it's a 59cc 4cyl iron-sleeved cylinder, so no need to mix 2T with oil (which I hate). Since it's iron-sleeved, it will typically outlast many latest offerings such as the alu-bore EU1000 series, etc.
regrettably, parts are quickly becoming obsolete, as do the carb (carb is already obsolete, good luck finding a brand new one somewhere out there regularly....I do have a hunch that somewhere in Asia (Thailand) there may be a few lying around, for the carb catalogue parts number matches some older small cylinder motorcycles...Keihin carb).
The fuel tank is lined/coated with an elastomeric coating (similar to POR-15) to resist in-tank rusting.
When I open up the generator for overall inspection (taking off side grill covers, etc.) what I saw was quality everywhere....the workmanship back then was simply excellent! This unit is around 40lbs (heavy by today's luggage generator standards) but nevertheless: being a traditional gen head type, it's actually one of the lightest, most-compact (and well executed) unit of all mass-manufactured unit by far.
While I may like to gather other oddballs such as E300, EX350 (2cyl), EX650, etc. fact is, my collection is now pretty much complete (have the EX1000 for running fridges; this EM600 for charging cellphones, providing non high-load electrical needs during extended power outages, etc.).
The more I venture into the older Honda generators, the more frustrating it becomes, citing that (a) most of the seriously old ones (collectables) are in questionable shape; (b) parts are obsolete, and with older units (most of them are in various distressed conditions when the owner let go); it becomes obvious that these units may not be worthy of restoring, afterall.
Things like pistons, ring sets, carb (always obsolete, no parts avail) parts, points (one must be ingenious enough to retro some NOS Honda motorcycle points to make things happen, and so on.
My biggest goal is to have something worthy of collecting, but also functional enough to provide me service when needed, w/o to worry about frequent servicing. That's why I stayed away from anything older than electronic ignition; brush type gen heads, etc.
These 2 genny (EM600, EX1000) will fit the bill nicely.
