Breez...The screwholding screwdrivers were almost a necessity working on the old Kohler K series engines.
Getting the screws back in the points and condenser...as well as the metal cover without them was a challenge..the K582 23hp was really fun..
After having a local machine shop continually butcher the heads we sent to them...which cost me a ton of extra labor , parts,...... and excitable customers that looked at me like I was stupid....I purchased the Neway valve tools. The best money I ever spent...nothing worse than paying for the work and then having to do it yourself...
BTW...the big screwdriver is from a Ford model A toolkit...( I think..RestroRob will know for sure )
The flat metal thing with the U shaped end is a homemade valvespring tool for getting under the springs on L head engines.
