my jubilee carb is 'blubbering" no black smoke, so I don't think its running rich, but the adjustments have no effect on the carb, either of them, it as a fairly new kit in it less than a year and I have had it apart twice yesterday, and don't see anything obvious in there its clean, and no torn gasket, the venture is the original, and fits so tight it wont remove, ive never had it out, any ideas? the cause; this occurred as I was brush hogging Friday, stuff was as tall as the tractor is so I had plenty of throttle on, the choke rod actually fell off for some reason, maybe rubbing vegetation released it, but the tractor flooded to a stop, ive got it running enough, [ its not missing yet], sitting on the trailer, and still have 30 acres on this job so im going to try to run it, but if you have any ideas for me id appreciate it, this tractor was running near perfect before this
