After running my 004583-0 portable for about 15 minutes (fresh gasoline), it started emitting heavy white smoke. One forum suggested water in oil or gas so I changed oil/filter, drained bottom of tank at on-off valve and purged fuel from tank to carburetor inlet - no water observed. Good compression (140-150) on both cylinders. Carburetor intake duct is dry and air filter is clean & dry. Generator is on level surface and well ventilated.

Planning a test run as soon as TS Lee moves away from Baton Rouge.

Did you have any additives in the fuel that may not have been thoroughly mixed into the fuel?

Ouch! Hate to put this out there, but sounds like something internal went such as broke ring,hole in piston??? Had my Kohler do the same thing and found out it had a broken piston ring and the heavy white smoke was oil burning in the combustion chamber. I hope this is not the case, but doesnt sound good.

The OP said that the combustion check was good, so that eliminates - at least in my mind - a hole in the piston. I agree that there could still be some sort of a problem with the rings.

Agreed about eliminating the hole in piston.

Is there a PVC tube from carb. to engine? Since it is new it could have enough vacuum to pull oil from engine and run it through carb.

Test run cleared up smoke. My wife tells me the smoke was a "bluish" color (I'm color blind). She also asked me if this was the same problem I had several months ago . . to which I replied, "what problem was that?" She said, "You old fart . . don't you remember when you had to tear that damned thing apart to get it running?"

Then, I recalled that, after sitting over the winter, a test run was attempted and the engine wouldn't turn over even with a good battery. Turned out that the carburetor float had become stuck and fuel gravity fed through it into the cylinders and oil sump. The cylinders had hydraulic locked and I had to drain the oil/gas solution, purge the cylinders, change the oil filter and repair the carburetor float. After all was said and done, the engine ran just fine but oil had saturated the muffler and showed up as blue smoke until it got burned away. This "old fart" is once again humbled by my wife's memory.

Thanks for yawl's input.

Don't feel like the LONE STRANGER, my better half reminds me of things I forget or neglect to do in a timely manner. That's what they are there for.
