For some reason the link to this engine isn't working. It's almost like HF pulled the engine from being for sale.
I tried a HF Predator 99 cc for my Taco II, The engine had such a mid-range vibration I brought it back for a another only to find out they have been discontinued. Too bad really as it is nice replacement but they might be having problems with Honda and copyright I hear? Side note, the latest HF flyer shows a 79cc predator on sale?
As for the cable hook-up you need to loosen up the nut on the throttle lever so it moves freely and also pick up another return spring and hook it up for a good throttle close action.
I pulled that plastic clamp out that holds the fuel line and put a bolt in there from the back to use as a mounting stud. I used a cable clamp on that stud that would hold the cable in place. I drilled a small hole out near the end of the throttle lever and was able to mount the adjustable cable guide there.
That motor should work fine but you might think about mounting it on some rubber if it shaakes bad.
Sorry no pics as I have a Honda GX160 now and am very happy with it.
