1985 Peace, mercy, and blessings of God be upon you. God has willed, blessed be God. Carburetor calibration watch. The price is 300 riyals. Condition: New, factory. Origin: American. It calibrates the carburetor to the millimeter and hair, and you don't need to go to the industrial area to tire yourself out, knowing that the cost of calibrating the carburetor is 100 riyals, and it might not be calibrated because the watch is rare in workshops. It calibrates all carburetors, whether American or Japanese. Final price. Good luck to everyone.
