Two 60 motors

Two 60 motors were won in Yahoo Auction the other day. One of them is Super Tigre 60 ABC blue head with rear disc valve induction type, as a matter of regret, several amateur lane chest nut marks were observed. Distorted brass cylinder was so corrected with fine tool as to mover smooth at DC piston position, this error might be an original one such as chrome plating error or some thing. Main bearing re-positioning and tightening screw head correction were done. Thanks to my careful and desperate efforts, she have regained her original smooth movement safe. Recent Super Tigre has some tendency to give less clearance between a brass cylinder and piston top than before, the character is similar with Japanese OS ABC.
Another booty is Webra 61 Speed with Dynamix carburetor that is famous for Hanno Prettner' "Curare" in World Championship over 40 years ago.
Remember that Prettner designed carburetor has a fuel acceleration pump construction, so the transient from low to high was so quick incredibly.
As for my Webra 61 Speed, it's front housing was replaced into YS 60SR's one and it was used under fuel pressurized condition. It had a good performance with it's lighter case construction, on the other hand the combustion noise frequency was higher than other 60 motors such as YS 60SR and ENYA 60X.
Because I obtained these motors at some cheapest prices, I'm now in a mood of  good luck.
