The last Tisco sleeve
and piston kit i recieved had a change to the way the sleeves were made. there was very little taper at the bottom of the sleeve
, so little in fact that the sleeve
would not start into the o ring.
i thought about grinding a taper on each sleeve
but discarded that idea as crude, time consuming and could potentially damage the o rings.
i thought about returning the product but that does not get the project completed.
so what i hit upon was to cut off the taper from one of the old sleeves, clean it up, and use it as a lead in guide to expand the o rings. with a little vasoline it worked perfectly.
Hope this helps someone else.
