Thank you Rich for the Onan information. I did what you said; remove carb, clean every orifice / Jet and hole. This 7000 watt is so smooth now it’s crazy. Loaded both ac units, lights and microwave and never missed a beat.
Thank you again.

Happy Holidays to you and your Family.
Be safe!

Exactly Curtis. First time I did it was better but surged . I spoke with Rich and he was pretty sure I missed some debris. Dead on! He has been a asset for quite a few on here and CR. Not worthy

Thanks

Just a FYI

Onan fuel pumps and carbs are on what we call intercontinental-ballistic back order....and have been for months.....with no idea of when they might be available.

I have no choice but to buy Made in China el cheapo fuel pumps and have used 2 just last week....they worked normally

An Onan carb for a 5.5 or 7 kw gas unit has a list price of over $300 !!

Now I am seeing a Made in China replacement at a fraction of the cost.....

Again I have no choice but to buy one and try it since I have customers that use their machines everyday to make a living.....

It's a "revoltin development" as one TV show actor used to say back in my ute..... Life of Riley I think it was.....LOL

Snow heading our way here by midweek......BIG SNOW......Oh shyt.....!

I also do small engine repair, and used to take apart, clean up and reassemble carbs, but since you can buy Honda, Yamaha, stihl, mikasa carbs for 10 dollars and onan for under 50 and fuel pumps for 20, I have to do what I have to do to keep customers going.

I've used a number of those carbs for less than $20 and they usually work fine....not perfect but good enough....

Small portable generators and other machines I've fixed for friends...and my own Honda I use at home in a power failure....

The last time I needed that Honda generator, the carb needle was stuck shut.....from the ethanol fuel.....

That is the second time that happened on a cheap carb and the last time it happened I could not get it free and working....Had to buy another $20 carb....

The biggest problem with any of these small machines is how to keep them sitting idle for long periods of time and not have a problem when you need them...just running them out of fuel doesn't always work well....

Some fuel residue lays in there and wreaks havoc.....The Ethanol fuel is worse for this probem....by far...

My Honda mower never f's up.....so far and it's a few years old...I run it out and drain all the fuel

I also drain the fuel from my 2 Onan generators......those carbs have a bowl drain screw and that works on those.....

I have taken bowls off of carbs that look like someone has spit tobacco in there it has been so bad. I quit telling customers to drain the carb if its going to sit, cause they won't anyway. I can't even get them to turn off the fuel while they transport so the float doesnt bounce and they flood it out. I solved my problem with my home tools, chain saw, leaf blower, edger etc, I went all electric lol.

Was sifting through junk this week and ran across my old Homelite generator, 1000-1200 watts maybe?
Anywho, the carb was varnished terrible 22-23 years ago, wouldn't run without the choke applied, rather than fix it, I removed the air filter, put a piece of duct tape over the carb throat, and proceeded to poke pinholes in the tape until it ran perfect. Razz Big Grin Cool

I looked at those carbs Rich..Nah! I have time and I like a challenge. I did have to back out mixture, ethanol? More fuel? I have pin gages and lots of tiny drills. HMMMM

Big snow? Watch out where the Huskies go..

I just had a phone call from a racing friend who is in Florida right now for a race at Bradenton this week.

His 7KW Onan that he did a lot of work to this past summer is pouring fuel out of the carb.

This cannot be fixed....floats go bad and there are no rebuild kits or parts for them available from Cummins-Onan

I told him he had only one option right now....buy the Made in China carb ....

The heat gets to those plastic floats and they are not full of fuel but they somehow get heavy and the flooding issue occurs....

I've changed a lot of carbs for both flooding and just running rich.....high float level.....not adjustable....

Until just recently I did not know there was even anything available other than Onan.....for a replacement carb.....

Buy American.....RIGHT.....sure....

Goob! Great story! Reminded me that Jeff and I had a Honda 1200 belt drive generator in the 70’s . We took that Honda all over Ca Racing, supported 2 cars and many parties. Never failed! I’ll look for it. I have the EU3000 also. It’s getting the fuel treatment too.

Many small engine carbs are so lean they need the choke slightly on, to stop them from hunting or missing....even when they are clean inside.....

I routinely pop the anti tamper cap off Onan's and richen them up 1/2 a trun.....

A very common issue on Onan 4KY's is they stall or surge with AC and more on and 1/2 turn richer fixes them......
