    That load compensation only occurs because the governor opens the throttle plate increasing intake airflow which lowers the pressure and the atmosphere pushes more fuel thru the orifice.

    FJ180 scored crankshaft and top bearing

    Image 6678 says Nope. The only way to save that would be clean it up, oxy/acetylene metal spray process to build it up and turn it in a lathe back to specified diameter. Not cheap.

    Is that your "problem" ? It's not a problem.

    Champion plugs are the standard answer when they have no clue. 🤔

    I was of the same mind set. My last aircraft was a Bellanca Super Viking, 4 tanks, two on either side. I'd never let anyone fuel it because the inside tanks would fill really slowly so I'd have to do the left then the right, come back to the left and then back to the right. The out board tanks...

    Up in PA several years ago a neighbor had a JD that would just die. Did all the normal investigations and determined it was a fuel issue. Looked into the tank and was amazed. Quite a bit of organic debris floating about including little leaf chunks. The amazing part there was no filter at the...

    Well..."water". Let's look for root cause. 1. Mower stored indoors? 2. Fuel cans stored indoors? 3. Same Fuel cans? 4. Fuel obtained from same, well used gas station? I don't recall having any flooding lately. Nor has it been excessively humid. As for putting gas in a mason jar....unless you...

    Welch plugs

    And just as a historical note....when Wernher Von Braun moved to Redstone Arsenal near Huntsville there was a conspiracy to welcome him...whenever he said "Huntsville" all the engineers would correct him with "Huntspatch" in a faux German accent. After a bit he started saying "Huntspatch".

    Only 9400 in USSF. You might see 15k tops.

    Welch plugs

    Their emergency should not be your emergency. Yeah, I know. My Dad was an IA level aircraft mechanic for over 60 years. He once said "I can't figure out whether they bring me all their planes because I'm good or I'm cheap.". He ate costs too. But it didn't matter......

    Welch plugs

    Welch plugs are there to hold something in like fuel in a carb passage but in most cases they are there to keep you from adjusting mixture screws or some other setting. Manufacturers don't trust the general public to make those adjustments.....and sometimes I don't blame them. This is a Welch...

    I have taken care of my neighbor's machines and mine....two stroke or four. I do it for free because we all have a lot of yard and last year one of them took their Zero Turn to a shop and they just never got to it in 4 weeks. I mowed their lawn for free, too. Hell to cut if it gets too long...

    I'm right over by Will Rogers airport on the west side...let us know what JD has to say....

    Welch plugs

    I guess it's too hard to fire it up in idle and when "surging" and place both thumbs over the holes and see if it smooths out..... I'll bet the oil issue is unrelated.

    2 stroke longevity - how many hours

    You mean "premium" as in price? Well, if you're using less per gallon of gas, but you'd need 2x+ as much of the other stuff....is the price per gallon of gas the same or less. And generally price is not the driver. Do the rings stay free? Do you have to decarbon routinely? Do the plug(s)...
