Model is MS1636NAVCC and serial #40980104061. I had the saw apart to repair an exhaust bolt boss. It ran fine before. The plug is wet but there is no spark on my tester. The module gap is .010". The on/stop switch and wires are good. I get 3.5 to 4 ohms resistance between the module metal mounting ears and the module connection spade with wires disconnected. Is that a valid test for the module and what should I expect for good or bad?
