I have an old 4hp Briggs I pirated off of a $20 garage sale Monkey Wards Tiller, I attempted to get it to run before I pulled it, but no luck. It seems low on compression, and weak to no spark.
it appears to be a #100202 built in 1965
I havent torn it completly down yet, but I did pull the head and found that the cylinder looks ok, with just a slight ring ridge, besides some carbon build up it really dont look that bad.
In the process of checking it out I found that the flywheel is rubbing on the coil, it appears that the crank bearings/bushings? are sloppy causing too much slop.
Questions I have...
Is it worth saving? Cylinder would be no big deal, but the crank slop has me worried.
Good online place for parts? I tried local, but it seems like all the mower shops either want to sell me a new engine at $270 or a "rebuild kit" for $240
I would also like to replace the carb with a mikuni or other type that is more like a motorcycle so I can run a separate gas tank (gravity feed) Any suggestions on what would work ? I will probably be fabbing my own intake manifold so Im open to anything.
Any performance improvements? anybody have any basic performance mods to share? I plan on at least doing at least a slight port job, maybe bumping up the compression a bit.
Its been many years since Ive rebuilt one of these, but I dont remember it being too hard.
thanks for the help!
