1984 Evinrude 50hp set up for about 2 years ran perfect when put up. spins over good an will pop every now an then through exhaust, fresh 50:1 gas, rebuilt carbs, top compression 130 bottom 80, timing checked good, plenty of spark will arc over 1/2", no blowing back through carbs, also checked both cylinders with a bore scope they don't a peer to be scored up. I understand low compression on bottom cylinder is a problem but shouldn't it still try to run on upper cylinder an just have a bad miss. I even tried a shot of starter fluid that I hate because it's to hard on the motor but still no change made zero difference. Thanks for any Help
