I am having trouble with my Mobility Big Dipper loader, I had it running a few days ago, it was ran great with no issues, I let it sit there idling for a few minutes while I was tossing some junk in the bucket. Then all at once the old engine started sputtering and running horrible. I adjusted the choke around and it didn't do anything. I made some adjustments on the carburetor and still nothing. The spark is great (just put on a coil about a month ago), replaced the spark plugs which didn't help. Fuel filter is not plugged and it is getting gas to the carburetor. Pulled the carburetor off and cleaned it out but it didn't help. Pulled the carburetor off AGAIN cleaned it, used the air compressor to blow air through it, nothing is plugged and it all seems to be on the up and up. Put the carb back on and still runs the same.
The loader will idle but it's rough, when I throttle up it pops, surges, sputters and smells of gas.
This has a Ford engine, same engine used on the 600 series farm tractors.
Any help would be great, I was in the middle of loading scrap metal when it started giving issues so I'd like to get it running as soon as I can.
