RE: Four stroke Engine Problems
That is a good link on rebuilding the Saito. The trick with the rubber band is worth noting. Only works for the Saito though.
Using a pushrod or something else with the small point to fit the hole it the cam works for timing. Even though it is loose int the houseing, you would have to try really hard to get it a tooth off. That would include not having the crank on TDC.
I've rebuilt both a Saito and a Magnum/O.S. four stroke and other than the cam timing, the Saito is a bit eaiser to work with. I expecially like the cylinder pulling like it does. Also, unless there is s compelling reason, I leave the piston in the cylinder to prevent damage to the ring. That is much eaiser with the Saito.
