OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Tech Talk Tecumseh TVM 140 Rebuild & odd mods

See Pics... After umpteen litres of solvent and hours of cleaning I finally got the Tecumseh stripped down. Top ring gap is way too big at 0.026" so I guess a set of rings are on the menu, the bore needs a hone and really think it could do with a re-bore but if a blind man could see it he would be very happy with it (no funds for that)

I can't help myself with the die grinder and the lathe got fired up to give the valves some attention (it was a fun night in the man cave ) Were mods required? no.... was it fun yes... will they help? yes a little better breathing... (The sharp edges were just radiused a little). I left plenty on the valves really for a future rebuild, but I think by the time that happens it will be well and truly an historical oddity..








The bore marks are barely discernable to feel, however the long wide one (photo 3) is the one that bothers me, we will see how it looks after a hone as per grumpys method in the drill press....
