3.5 briggs

#1
Anyone here ever Build up a 3.5 hp briggs? Are there many parts to make'm push more horse power? Is it worth it? I've been seeing alot 5hp briggs online that are pushing 12, 13 and even 15 hp. If thats the case could a 3.5 stock be made to get 8-9 horse power?

if you really want to spend ALOT of money you can build a open 3.5 Briggs pushing about 17 hp but it will cost you about 700 dollars if not more.
