Well guys over the weekend I started up the old beast and although she would still randomly throttle down, like when ever you release the forward interlock switch, slowly the problem cleared itself out. I would still get a little surging when I would engage the tines into the ground but that isn't anything new. I had put some more seafoam down her gullet too so maybe it helped cleanout whatever gunk might have gotten stuck. As a side note I always make sure to run the fuel out of the carb after every use. The carb bowl has a wicked habit of developing rust in the bottom of the bowl from the little bit of fuel that remains.
Now I just need a new throttle cable, Left tire, and tines. Throttle cable broke at some point in the line, tire likes to go flat, tines are looking like blades not tines.
