Was a bit disappointed with the Victa self propelled slasher when I looked underneath and found no blade carrier and the end of the crank seems a bit strange. I think the motor may be different than the standard side pull motors because of the drive belt pulley. Be a while before I get to have a real look at it
That looks identical to the one I brought over to you for an engine swap. We did have a few issues stopping the fins from hitting the frame from memory.
