Default Engine for Yerf Dog 3203

I have a yerf dog 3203 that I bought with no engine. I have the jack shaft and clutches ect all i need is an engine. Can someone tell me what engine options I have that will bolt right in? And the best place to purchase. I would not mind going with a little more power than stock, as long as it is still a direct bolt in.
Thanks

If your interested in used engines, look on craigslist for Honda, Techumseh, and Briggs and Statton engines, 5-8hp.

If you want a new engine, I would suggest either a Honda, or a Robin Subaru. Subaru has newer technology than Honda and is less expensive, but Honda has more performance parts available.

Not all of the 7-8hp engines will fit, but most 5-6 should. Make sure whatever you get has a keyed shaft (with a diameter to match the bore of your clutch). I would not suggest you buy a more than 8hp engine if you have a 20 or 30 series clutch.

A clone engine from Harbor Freight will bolt right on, that's exactly what I put in my 3203, usually you can find a coupon for $99 or $109, then for more power, get THIS and you'll be around 7.5 - 9 HP, you will save hundreds over the name brand engines and as long as you maintain the clone it will perform for you

usually tecumseh engines will have the same mounts up to 10hp. (im putting a 10hp in a mini bike) but briggs, that ive seen, have a larger mount 8hp and up.

a 6.5 clone will fit the bolt pattern of the old tecumseh, a 13hp clone will not. it would really help if they stuck with one mount up to a larger HP rating

Regarding the HF clone engine, it looks like the rewind would need to be turned either 90 or 180 so it pullls out the back. Is that correct? Also does it require any modification to get the throttle hooked up?
Thanks

It depends on how you mount the engine whether you need to turn the pull cord but there are 3 8mm bolts involved so its very easy to rotate and you get 6 positions to choose from, throttle linkage is easy as shown here:
