Do you play guitar mr Funk or maybe your buddies do? You could gently feed small guitar strings through every port you have access to. While i hate cleaning carbs ive never met one i couldnt clear to make work.

But also never disassembled an Onan carb. I have seen where small engine carbs can be cleaned over and over and over. Finally the small clog gets agitated enough to break free.

Well, I got a shiny new carb installed today but it did absolutely no good. Genny still ran like **** and konked out after a minute. Actually worse than before. I checked for fuel at the carb and it looked like I might have a fuel line issue, so I ran a short new fuel line to a small gas can down below the rig. Same performance, it would run like **** for a second and stall out.

But wait, here's the best part! Out of the blue it's now blowing 5amp fuses every time I hit the start button. Awesome! I love working on this thing!

Somebody help me out here before I just throw the **** thing in the river and go buy a new genny from Harbor Freight.

I recommend you cruise over to the Onan experts here:

You will need to post your genny model number and serial number.

How about the fuel shutoff solenoid intermitentent/bad? Or is it part of the new carb?

New one came with the new carb. I suppose I could still test it though. Doesn't explain blowing fuses though.
