My first fully edited video production. Time-lapse of a whole day rebuild of a 1992 11.5hp Briggs and Stratton Flathead Ride-on mower engine for a future lawn tractor project. Made using Sony Vegas Pro 9
looks good mate! i like the valve grinder. wish i could afford one for my self but theres more important things on the list like a decent lathe lol. good to see someone taking the time to do it properly.
@Jaytheozzi yeah it is a nice grinder, my dad's work was actually gonna throw it in the bin! It was perfectly working and everything, just all the new kids there had no idea what it was or how to use it! That's how we got it for nothing.
mine had the seat replaced but the valve was not closing all the way so i had to grind the stem and lap the valve. It regained around 20psi so the engine ran 10x better after.
Hi i have old 12.5 Briggs with side plate Gov that seems ok and smooth running and loose when idle throttle then tight at full throttle BUT i can only get 1/2 power and push throttle further and no change. So does this mean the govt arm has slipped a little in that clamp OR the govt spring needs adj- and how? If i move the Gov arm myself, i get full power so its not moving far enough through that spring? thanks
@30GB yeah with most of these L-heads they will almost always need a stem grind because they are set very close from factory, plus wear. I usually go for around 0.25mm or 0.10" and they sure do run much better after.
@nick89gm If yours has funny bolts, it must be different to mine. This big end has standard 6 sided (hex) bolts with a locking plate (which I was bending away with the screwdriver at 3:09) try and use a star socket on yours if they are not hex bolts. I forgot what size mine were, sorry. Good luck mate and thanks for watching.
@Jivemaster2005 I did lightly hone it, I tried to show at 4:31 but the camera didn't pick it up. plus I had to re-use the original rings which were worn in already. thanks for commenting.
