Onan starts and dies

I used to keep a bunch of old leftover can tips that I had cleaned and simply replace the tip when I encountered a clog..

Not so much now days, the clogs seem to happen deep in the can somewhere and all I end up is two tips that need cleaned and a completely full can of paint that if only I could get the clog cleared I would be so in debt to the can manufacturer for saving a couple of bucks and help not adding to the landfill a full can of paint..

The last 5-6 cans really have made me angry about that, didn't even get a full squirt before they clogged off completely.

Took a small board the length of the can, added a short heavy duty bungie and a 1/4" carriage bolt in the center of the board. Then strapped the can to the board and the leftover threads of the bolt go into my 3/8" drill..

Take the whole thing outside and twirl the can at high speed for 15 minutes (safety glasses and other precautions apply just in case it goes south in a hurry)..

Much less clog issues after it has spun for a while.

Have looked into paint shakers but even air driven ones are awful expensive.

Interesting, I do not use a lot of spray paint but have not yet had a can clog up, only the nozzle! I hope you are not using that electric drill out side when it is raining out LOL

Carb is back together, hopefully can test it Today. I looked all around and see no extra parts.

Success, as soon as gas got in the carb it fired right up. Only ran for a couple minutes, need to check if it is producing power. Need to get it outside to run and test. Shocking how little gunk stopped it from running and leaves me wondering if it had run even a little I could have forced the naptha and gas mixture thru it??

SWEET!

Doesn't take much build up to foul up the works..

Shame they didn't put a drain plug on the bowl, it could use one the way the jet adjustment goes right through the bowl.. Fuel just sits in that bowl picking up moisture and the moisture simply attacks everything it touches.

But alas, omit a 10 cent part and now they have repeat customers for a $300 carb! Genius!

The real genius is selling the gen's to the manufacturers so cheap that no one can compete with them. Then making the profits from replacement parts they sell to the victims that buy them. A new Roadtrek 2.8 carb installed at Onan is $800 to $1000.

Shockingly there is a drain on the bowl! I do not understand why the drain plug has a spring on it?? Does not show on the drawing I posted, but shows in picture under the altitude adjustment knob.

Interesting..

I remember a few small engine carbs from late 60s that had a spring loaded drain plug, just push in to drain and when done draining release the plunger.. Downside to that one was the seal would wear out from engine vibration or get hard from age and no longer seal after a while..

The newer ones with a drain plug I always try to place something under the carb to catch the plug just in case I drop it.. Things that small tend to disappear forever in grass and even if it is on concrete for some reason. Not like the average person is going to have a metric size and threaded screw that happens to be the correct size laying around..

Did think about if one wanted to one could add a switch to the electric fuel pump and turn off the fuel pump and let the engine drain the remaining fuel from the bowl.. Still would leave some at the bottom of the bowl but much better than letting a full bowl go stale. Downside is remembering to turn the switch back on after the engine quits so you don't end up wondering why the gen won't start the next time.

anything would help, this drain is threaded with a spring, if it starts to vibrate loose the spring will help it fall in the grass. No doubt patented by Onan!

When all is said and done the best way is junk the Ohno and use non ethanol in the Honda!!
