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 :bash: :bash: :bash:

cheers :confused: :confused: :confused: :confused: :bash: :bash: :bash:

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