Champion genset starts and runs with battery, but not with recoil start

I'm a carpenter, not a mechanic, but I do limited work on my stuff with good success. That said, I have a Champion Model 71530 9000-watt genset. It's a dual-fuel unit that starts either with battery/switch or recoil/pull. We've had this genset for several years, and it's always started and run fine when using the battery method. It has NEVER started by pulling the rope, not since we bought it. I've let that go, but now I want to be able to pull-start this unit. My question is: What is unique to the recoil start process that is broken? I'd really appreciate any input on this post.

Choke plate closing all the way?

I'm sure that the choke is positioning fine (just replaced the carb and I remember checking that), but I'll verify that. Is that more critical with pull start than switch?

I have not. I will check that. I keep it in a plywood box with my snowblower, and it's only been outside and running maybe several hours in several years. Maybe 20-30 hours, but I believe that's high. But, I'll check it.

does it have too much compression to pull over by hand, or is it one that you pull and pull and pull but it never starts? How old is the fuel?

Are you turning the switch on? The electric start probably has an "ignition on" position and that allows spark to the plug and needs to be on for either electric or manual starting.

I'l start by asking what is the actual make of just the engine on this generator?

Then I'll say that if it's starting via the electric battery then listen to echo what "slomo" stated in post #2....

I'll finish by saying that there's probably rust on the fly wheel and/or the armature preventing spark...

When you say it NEVER started with the pull rope, does the pull rope turn the engine? I think that is what you are saying. There are “dogs” in there that should engage the flywheel, maybe they are stuck?

It has been proven the magnetic field flux is not affected by rust.

If its like my champion you just hit the starter button and the choke is automatic but if you use the recoil starter you have to turn on switch and set the choke manually or it will not start.

Pull spark plug, squirt about 2cc of gasoline in the hole, put plug in, apply choke, closed to 1/8th throtte, and pull. Should fire right up. If it does that it's capable of being started by cord. Now you just modify your procedure next time. Don't pull the plug just apply choke, throttle, and pull. But don't leave the choke on for more than two pulls otherwise it may have pulled in two nice slugs of fuel and flood. If it fires at any point it should run. Don't pull more than two times with switch off and choke on. Switch on, choke on, pull no more than twice. Choke off.

that is generally true; however, the poster says: "It has NEVER started by pulling the rope, not since we bought it.". that said I'd guess (?) there might be a severe rust build up . . . . . easy to check that first then move on to something more severe. jmo

The start key has to be in the on position and it may take several times pulling on the starter rope for it to finally come to life. Being a 9000W unit, it will take quite a bit of effort to get enough starting RPM.

Next option would be to remove the air cleaner and give it a short spray of carb cleaner to prime it and it will start. DO NOT USE STARTING FLUID. Starting fluid is harmful to small engines.

like so many, it appears the poster wants to keep everyone in suspense, ho-hum . . . . . 😙
