I have a agrifab leaf mulching tow behind vacuum that came with a briggs intek 190. Well the motor has been terribly neglected by the previous owner. Never changed the oil sat outside for years and got alot of water in it. The engine is not worth trying to salvage as it is in that bad of shape. I tore it apart and the cylinder bore is bad the ring gap is excessive..etc. I am looking for a intek 190 on craigslist and such (cause im cheap) and all I can find are intek 190's with straight 3/4" output shafts but the one on my agrifab is tapered. It starts at 1" and tapers down to .890" at the end. What can I do? I thought about buying one with a straight 3/4" shaft and swapping the cranks out. (but I really dont want to). I guess my question is did they use this exact engine in any other application? generators, log splitters, etc. I also see there is a intek 206 that is very similar. I am wondering if that will work? what engine can I use that will have a taper to its crank so I can press this impeller back on it. Sorry for the long post and thanks for any input.
