Champion gen warm starting

[EldIr]

Bought the 3500/4000 Champion this year since the Yammie 2400is wouldn't run the air. Champion runs 13.5 a/c no problem. Starts first pull when cold. The problem is if it's been running, shut off and then try to restart while it's still warm. Takes somewhere between 1 & 2 million pulls (I lost count.) Have tried different combinations of no choke, 1/2 choke, full choke, nothing has helped. It isn't very often we have this scenerio, but it's aggravating when it happens.

I need to shut the fuel valve on mine too.Bouncing on the road is enough to flood the carb if the valve is left open.On the carb,there is a hidden low speed jet under the plastic cap by the choke on top.You need to pull the plastic cap off to get to the jet and blow it out with compressed air.The cap goes right back on after cleaning.That will solve your starting issues.

Thanks, I'll make note of that for when I put it in storage for winter.

Speaking of winter, what is your crankshop 1000 in? Drag sled? Trail sled? Do you go to the UP much? I trail ride an XCR800 and just got an M20 Airwave skid to put in. I know summer is short, but I'm already looking forward to winter!

Drag sleds.Prostock 1000 cc. Just a hobby runs 5.40 seconds at 125 mph 1/8 mile on ice.Used to go on a 10 day trip from the bridge to Newberry,to Copper Harbor,to Hurley Wisconsin,to Mackinac Island and back to the bridge.Haven't done that in about ten years,kind of got out of trail riding when everybody thought they needed to run the trails at 75mph.

Yeah, 75mph is kinda slow. I hate when those guys get in my way:M

I did not bother telling Champion about the gas problem. All they would do is tell me to bring to a service center for warranty repair. Since it isn't an issue as long as I shut the fuel off, I'll just pull the carb and go thru it when it's time to put it away for winter. Like I said, I wouldn't be at all surprised if it's fixed itself just from the vibrations of running. It does run like a Champ and is a phenomenal value compared to other "bargain" generators.

WOW brand new out of box should run like a champ however it did not.
More reason too suspect something got in that needle and seat or it is just stuck right out of box. Did you explain this to the support team when you contacted them? They are turning off gas to stop problems over time.

I suggest using gas stabilizer after cleaning the carb

It was brand new out of the box when the engine filled with gas. First time it was used. Maybe read the posts more closely before offering a definitive answer (with an exclamation point) that is clearly incorrect.

read the post above from Champion support, turning off a machine should not fill it with gas to the point its pouring out the carp. you obviously have a problem

Yeah, I know that. I also know it's not dirt or something caused by poor maintenance or neglect. I'm sure the float stuck. It might be fine now that it's been run many hours (vibration may have cured it), but I've been shutting it off by starvation as instructed in the manual. That doesn't explain my initial question in that it starts fine cold, but not warm. Both startups are after shut down with fuel shutoff so it's not flooded.

I emailed Champion tech support quoting the shut down instructions from the manual. Here is the reply.


"Hello,

No it not a mistake. If you are using the generator throughout the day just use the on/off switch. If you’re putting it away for a day or longer we instruct to turn the fuel valve off and run until fuel starvation. This does a few things:

1) Allows generator head to cool

2) Allows engine to cool

3) Leaves carburetor bowl and fuel line dry.


With the introduction of ethanol you cannot just simply turn off the product and allow the fuel to sit, especially un-treated fuel. Areas with high ambient temperature and high humidity can start having fuel issues in about 3 weeks.


Please give us a call on our toll free support line at 877 338-0999 ext. 401 if you have additional questions or concerns.



Thank you for purchasing a Champion Power Equipment generator.

Maybe not a typo but a mistatement for sure. No generator has to be run dry of fuel in the carb every time you turn it off. It's a long term storage statement that got lost in the translation.
If the engine loads up with fuel there is a problem with the float or needle and seat in the carb.

Mistatement sounds better but it sure got lost in translation!
Just plain common sense needed here.

I have found hundreds of mistakes in diesel manuals including Caterpiller Diesels
One example is 190 foot pounds on 5/16 coarse bolt.
Common sense says NOT RIGHT.

Like I said, they changed something. Page 14 of the current manual.

Stopping the Engine

1. Turn off and unplug all electrical loads. Never start
or stop the generator with electrical devices plugged
in or turned on.

2. Let the generator run at no-load for several minutes
to stabilize internal temperatures of the engine and
generator.

3. Turn the Fuel Valve to the “OFF” position.

4. Let the engine run until fuel starvation has stopped
the engine. This usually takes a few minutes.

5. Press the ignition switch to the “OFF” position.

Important:
Always ensure that the Fuel Valve and the
Engine Switch are in the “OFF” position when the engine
is not in use

This is a typo for sure. Call Champion and ask, No one should follow that unless storing for extended period.

You might think it's a typo, but the online manual on Champion's site and the hard copy that came with the gen say the same thing. A typo is when a word is misspelled, not an entire instructional paragraph.
