mac 3200 coil/carb trouble?

I seen your post on replacing the fuel lines on the 3200. I just replaced all of mine. Before I replaced them the saw would start and then stall when throttled up. I cleaned carb. without replacing diaphram and metering gaskets. It started fine after I primed the new fuel line, I ran it a bit with no problem,got back to the tree and it started to do the same thing. would replacing these gaskets help or could it be a coil problem. I get spark but don't know if it's strong enough. Would you know the coil # and is it difficult to replace or should I just find another saw?Thanks
