yessir got a choke cable as well, just waiting for a recoil assembly to be delivered, then i can actually diagnose this unit
Well i finally got this basket case assembled so I can diagnose it.
Shes surging bad, but it's weird, pulling the choke has very little affect on the surge, it will surge up until get to almost full choke, then it will start blowing black smoke and running rich. There's no sweet spot to stop the surge, so that makes me think , maybe a governor or load issue, for the heck of it I disconnected the wires coming from the generator head and restarted it, issue persisted.
I also removed the governor link and did the throttle by hand, any less than 1/2 throttle and no choke, she dies...
This problem has occured in the carburetor the customer installed, one I installed with new gaskets.
I'm thinking of opening the carb up again and enlarging the jets to see if that gives any improvement, but on the other hand, I don't think it will since the choke never gets rid of the surge, it goes from surging to chugging rich with no in between.
Spark Plug looks like a lean burn.

I put a new NGK in it, since it had a Torch.
I'll put spark tester on it and see what the sparks doing.

Hi Scrubcadet10,
Check out James Condon and his generator repair videos online. He tackles some pretty interesting carburetor surge problems.
Here's a video of this little pot.
Went back through the carburetor, and checked spark, good bright blue consistent spark.
One thing I've noticed, quite a bit of fuel spray back out of the intake when it bogs..

Hi Scrub Cadet,
From watching your video, this is a bleed air jet problem.
Have the valves been checked for proper adjustment and to make sure a spring has not broken? Anything is possible when dealing with a basket case project.
Aftermarket carburetors are some of the worst to deal with for this problem. I like to think just because they will bolt on and fit, does not mean they will work correctly.
James Condon and Teryl Fixes All have some videos that talk about this subject, but I have not found one in particular that I could attach yet. (I will keep looking)
You will need some very fine wire drills to resize the bleed air jet that is pressed into the housing below the base idle set screw.
There is also a rare chance that the flywheel has been tampered with by the prior owner and the flywheel nut was not retightened properly. It takes only a degree or two of key shear to disturb the exact timing on these small engines.
