Engine Questions

I'm looking to buy a Honda GX25 or Honda GX35, but has anyone ever used a Briggs and Stratton 800 series (2.9L qt gas tank) engine or 550 series (2.0qt gas tank). The briggs and stratton are classified as "other engines" but can be used for multiple uses such as lawn mower, edger, whatnot. I'm only looking into a 4 stroke engine without mixing the oil and gas, and I really want the engine on the back of the bike. Let me know what you guys think.

@Ibedayank, sorry here are the Briggs and Stratton first
1. http://www.briggsandstratton.com/en...ies&id={B95F8B9B-DA04-4811-B42A-11329358FADC}

that is for the 550 series its 127cc's WAY more than I need anything 50cc and above in michigan requires insurance, so I'm looking for 49cc and below. Has a 2.0qt gas tank 4 stroke

2. http://www.briggsandstratton.com/en...ies&id={9EFC91CC-9803-4EA1-9A14-6C4EDC7B709C}

this is the 800 series again its 205cc's so overkill, I was looking at the 2.9qt gas tank 4 stroke

3. http://engines.honda.com/models/model-detail/gx25

This is the Honda GX25, its 25cc's only a .61qt gas tank 4 stroke. I can get one for $200

4. http://engines.honda.com/models/model-detail/gx35, This is a Honda GX35 its 35cc's has a .67qt gas tank 4 stroke. I can get one for $210.

5. http://engines.honda.com/models/model-detail/gxh50, This is a Honda GHX50 this is a 49cc 4 stroke, .81qt gas tank, requires me to use gasoline at 86 octane or higher.

6. http://engines.honda.com/models/model-detail/gxv50, this is a Honda GXV50, 49cc's, .29qt gas tank.

Looks like I'm going for either the Honda GX25 or Honda GX35, currently searching the internet for a modification to hold 1 gallon of gas without leaking.

chaindrive friction drive bolt another sprocket to the rear wheel or use the gears already on the bike
some type of belt drive?

I am planning on bolting the engine to the back wheel, I was planning on using the gears already on the bike IF it works out that way. this video basically explains what I'm trying to do http://www.youtube.com/watch?v=zpjh2EfzqhA trying to contact that guy personally, so far no response
