Crankcase bolts/screws.
« on: June 27, 2014, 04:34:17 PM »
Tried to slacken a bolt today,to remove broken cable clamp on 400F. This is what happened. :( :(
Someone in the past has tried to slacken and butchered screw heads. Will have to heat them,and try impact driver.
Have never split one of these engines. Will have to now!!  >:(
