    I would second the tube. I go off road often and like the thicker slime tubes. We have these stupid straw liike sticks and if they catch the tire just right they and make a small hole, but they dont seem make it thru the tube; if they would get thru the tire and tube , the slime would fill the...

    Removed Head to Investigate. Here's what I found.....

    You need to check your valve gap! Whit the piston at TDC ( which is actually down about 1/ 2 inch from the top ) can you push down on the top of each valve an spin it in circle you should feel resistance ,,,,, if it spins too easily then its not shuttuing all the way. If the valves are...

    stains in Aluminum wheels?

    I have actually taken a large drill bit and a ball of steel wool. Turn on the drill and let the bit grab the ball of steel wool and let it wrap around the bit. About the size of a tennis ball. Then simply high speed buff the wheel. Just be careful and dont expose the bit,,,, let the steel wool...

    Short Shaft Briggs 5 Flathead

    Just flip your clutch around with the teeth facing in. Also you can use a bolt and washer on the outside for extra security . Also keep your eye open on ebay for a used crank that is longer ; dont pay too much sooner or later a cheaper one will show up!

    Loose Piston Rings/ Slap

    I checked the ring gap on my piston rings and they were within spec . However i noticed i could wiggle the piston side to side really easy inside the cylinder! I replaced the rings and now the piston is nice and snugg within the cylinder. The old rings were thin and brittle. Even though...
