Love those little buggers...........in red of course......another real nice 490 drifted into the shop a week or two back....haven't had a minute to look at it other than to say it looks in great condition. Performance wise the 590 is way superior.....not exactly the same casting number as the infamous 45cc closed port Husky but will mount up to either. Not sure what the difference is...can't tell by just looking...look identical. Of course I've found the high strung 590 is not as easy to keep running properly as the 490 (5000/5000+)....they really run good.....every 490 I've had you set down idling and walk off and it just idle away until they just run of of fuel. (Thanks again for the 590 Jerry)!!! Love that saw!!
Has the recoil stood the test of time?

I had replaced the recoil on that saw twice for its previous owner, he had ripped them to shards , must of been his starting style. I put the 3rd one on but he didn`t want it back, claimed it was too difficult to start it.
Yeah....Dunno....I've not had any trouble starting it.......it doesn't like to idle for extended periods.....After fussing with it a bit I just accepted that's the way it is ....so I don't let it!! Runs real strong and fast.

My old man last year found this 5000+ at my local trash transfer station. he said the guy flung it off his truck and claimed it to be a POS..he picked it up knowing i have a chainsaw addiction. finally got around to it. she runs but only until she heats up.. it has a crazy gas venting system, that once hot it bubbles gas and turns off..

clutch&drum
so far i replaced the flywheel key (it sheared 2 btw)
put new spark plug
new coil
oil cap
clutch cover had a crack in it, JB weld back together.

anyone have a 5000+ that vents weird?
If you haven't already, check that all the crankcase/tank bolts are tight.
The fuel tank should be vented into the cavity between the crankcase and fuel tank via a hose_sintered block_hose assy into a black molded plug n the top of the case. If the cases are warped and/or the gasket has been allowed to move, pressure could be being equalized in all sorts of directions.

the only vent i have is a modern screen type that sits right out of the tank. while running, gas bubbles out of it like mad. i looked at the ipl and it shows a complete vent hose/filter all the way to flywheel. i don’t have. someone previous must of ripped it out.

It's normal for fuel vapor to exit via the vent under pressure. The idea of having it carried by a hose into the cavity is so that it cools that space as it depressurizes in there and any condensed liquid fuel drains out of the opening in the bottom of the case.

Thats good to know on your high compression version. Those aren't the strongest starters.
Mine both broke due to kickback. One cover merely cracked as the cord pulled itself tight, the other virtually exploded. I gotta put a rubber bumper in there somehow...

correct starting procedure helps a bunch..
