A 160cc two stroke wont be enough power. Youd have to pair up.
You can buy a pull start 6.5HP horizontal shaft motor new off eBay for under $200. You can get them with a 2:1 reduction box attached for an extra $150 or so. They had E start ones too.
I tend to agree with the others, its a bit of a dangerous game. I have a 5hp rover mulcher here that i am going to rebuild, i will take pictures of it when i strip it down and get into it, so keep an eye open.
Some thing easier, manly and a little less dangerous would be using that Victa motor and making a lawn edger. Just a thought.
