I seen the post on performance parts for a Honda engine, was thinking about upgrading my Briggs "L Head" engine. Also Does anyone make parts for a Tecumseh?
Theres not much performance parts for a Tecumseh. I'm pretty sure theres air filter adapters, Headers and I think thats about it. There not commonly modified. However you can do cheap/free mods like porting, timing, shaving browes and so on.
