So far making progress with this project.  While waiting on the powerhead parts I was able to get the lower unit apart, clean everything up and replace the water pump.   The gear oil was in surprisingly good condition with no evidence of emulsion.  I think I will eventually replace all the lower unit seals after I get it running and everything dialed in.  I have a couple questions about the carb relating to the packing around the needles and the welch plugs.

• Do you recommend any sort of lubricant for the packing material?  My carb kit came with what appears to be cork packing washers.
• The parts list shows the packing nut directly compressing the packing washers.  Would it be advantageous to add a small hard washer between the packing nut and the packing washers?
• In addition to the aluminum welch plugs I’m familiar with, there appears to be molded lead welch plugs sealing some of the smaller carb passages.  Can I just pound a piece of small lead shot in their places when I put the carb back together, or is a more specific procedure required?

 

Thanks!
