My 52 pw did that years ago, I pulled the carb and the crankcase vent poipe I found a large amount of carbon had built up at the vent inlet, I drilled it out with a 5/16 bit vacuumed the loose carbon out of the manifold and it has never had the severe blowback since! I'll bet thats your trouble.. good luck!
