Ok. If you can stick a screw driver in plug wire clip and it jumps min 1/4 -3/8 inch your spark is good enough. Next steps: Make sure the pulse port going to the carb is clear all the way to the crankcase, and oriented to the carb correctly. Next make sure the pulse port on the carb is clear to the diaphram. I did that on a chainsaw carb swap once, couldn’t figure why it didn’t run correctly….. oops! If all that is well and the carb is clean and in good shape, give it a prime of gas in the spark plug and it should light up. If all that fails, turn the high and low speed jets out 2 turns total. It will draw only light air at hand speed turning fly wheel. Thr reed plate gasket isn’t made wrong and catching the reeds it it? It is possible that some one rebuilt the carb and put the wrong choke butterfly in there. I had a Mono 48 saw that needed the choke plate to cover 95% to start it. Any less and not enough suction to opperate the Lauson Power Products carb.
