Engine swap question
 

I have a cub 3204 with a CH20 blown engine and I found a parts gt2550 with a CH670 engine. I'm fairly sure it's a direct easy swap. Maybe exhaust needs changed, but everything else bolts up, plugs in. Am I correct? It will be the first full engine swap I do on anything this big, so don't really want to mod anything crazy. They both go to the same service manual. I just want to confirm I'm not missing something out of inexperience

I'm pretty sure that would be an easy swap. The 3k's are different than the 2k's so you will need to reuse the muffler, manifold's, pto system and a few other things I'm forgetting. You will need to see where they pickup the vacuum for the 3k pto. It probably has a fitting on the intake manifold for the 3k machine but I'm not sure the 2k will have it.

Here are some free manuals if you don't already have them.
