Hi
Go to the site
www.rsengines.net/brute45/brute45.html
good site with instructions and photos and parts to convert 33 and 45 cc Homelites.
surf the site , have photos and good instructions your engine is named Brute 33
Go to the White pages ( printable) in the site.
for my point of view this is the best site with Homelite photos conversion.
I make my own conversion of a Homelite 38 cc with parts machined by a friend and this site is very good on Homelites.My Homie is in a test stand and put original carb rotated with a teflon piece and CDI.I have bought a chainsaw with little use and engine like new.
Other good site is
www.rcfaq.com
but I saw in RCU it is temporarily unavailable.
Good luck
Jose
