time to take the valves out and file them and the head with carborundum paste
|
each valve has 2 kings of not symetrical spring therefore the assembly sould be correct
|
|
|
taking the valves out you need to press them inside with this special tool and take the colt holders out
|
the new oil retainers sitting on the valves
|
this is the big aluminum nut the I had to open so I bought massive air hummer, here I drilled a small
reccess to punch it manualy with sand hummer
|
|
|
assembling the valves and spring back into place
|
abundance of tools and just a little mechanical practice
|
|
replacing the valves oil holders with the ones I got with the package
|
replacing exhost metal gasket packed altogether with the kit
|
the camshaft with the small pin (right below the niche on the left side of the axle)
|
|
measuring the valves stem to see if it fits the correct service limit diameter, it was
|
|
before/after valve clearance to conduct the next engine start
|
|
taking measurments of the piston spring length in rest to see it fits the correct service limit
|
putting the cogwheels gave me a headache so I printed a "before picture" to help me assemble the parts
for next fault start test...
|
the second culprit was the carburator, thats why I ordered from procycle.com a new sophisticated one
|
|
smearing carborundum paste (box at the right) on the valves and head bores and twisting them one on each other
to make a clean pressure resistant match
|
the stator before I use the new gasket (wrapped in nylon on the upper left side of the picture)
|
before closing the head you need to apply hot silicone paste- but sure not as much as shown here-
this amount might couse a oil passage being clogged
|
|
|
before assembling the clutch starter you can see the big cogwheel (which I replaced later on) which
became fault after (or maby during) the three plus years it stayed in the garden.
|
the half decompression was left outside on purpose but stucked just a little so that no oil will spatter
