Hello All,
Great info here as usual. I am working on 25cc homelite (weedie) and 33cc Homelite (chainsaw). I contributed a little on the 33cc thread. As it has been pointed out, the chainsaws come with a carb with enough oomph and the weedwackers need a carb upgrade.................. well , my 25cc did anyway.
Both were pretty easy to do using information posted here. It would have been tough without it.

I would advise scanning through the threads devoted to the conversion subject. It is exceptional just how much can be learned in these threads. That's my $.02 (I get a charge out of the humor here too).

Doug
