what i did is i welled on the cam shaft just a little bit then grinded it down to where it is nice and smooth, the i took a drimmil to the head and carved pathes for the fuel and gses to flow though the head easer. i know it sounds pretty stupid and it will probly blow my motor soon but i did this like allmost 2 years ago and its still runing very good. i made my self feel realy good when i did this because i gave it a lot more hp for free and thats what i was going for was free

Hey guys, i didnt think you could weld the loabs on the camshaft? nice!!!!!!
also, i have what i think is a 10.5 briggs flathead and when i fire it up it sounds like it is labouring down low,i think the carb is off a earlier motor so i think it is either flooding or starving for fuel down low what do you guys think? any help would be great
cheers

You use just as much low end as top end. Clean out the carb real good and see what goes on.
