Honda eg3500x starts up fine but will only run choked.

http://cdn.powerequipment.honda.com/pe/pdf/manuals/31ZB4770.pdf Won't charge? Charge what? This generator has bo battery charging capability.

There is a series of spacers and gaskets that go on in a specific order. I can't remember offhand. If you get them on wrong it can mess up the alignment of the choke control which causes it to bind up and not move freely. That can make the engine run rich and smoke which makes it look like it is burning oil.
Check online for an exploded view of the gaskets and spacers along with the bracket for the choke control. Make sure they are aligned properly.

tune up,fuel filter.

the motor wont rev high on choke.the motor is suppose to fire once on choke. then turn the choke off.pull the start cord and the motor should start and run.check that the throttle conrol is on full. it should run fine.

Are you pushing down on the choke lever really hard? These things have a really tight choke lever. I choke mine and reduce the choke to maintain 1500 or so RPM until it is slightly warmed up. Then it runs fine. These are cold blooded machines.

Hope this helps.

check fuel level, u may need to check the flow of petrol to it,,Also if that does not solve you may need to service the carb and check fuel filter,air filter etc...

sounds like bad fuel try adding some fuel stabilizer.

Swap out the carb for another if you can get one, if not bring it to a honda dealer to have it cleaned.

When starting any engine, run engine until it will idle without the choke on, then ride.
