I was given a 1982 D-50 last week. Price was right.
It had two spark plugs broken off. #2 & #3
Extracted them, then pulled the head. Found cracks in the head in the #2 and #3 cylinders.
Threads for #3 cylinder got damaged.
Took head to the local head shop, and it will be ready tomorrow.
looking for any information on rebuilding the Mikuni carb.
Do not want to take it apart blind.
