No, this one is fitted with the plastic inlet that is screwed onto the carb body. The storm shield that you refer to s still available but not fitted the case of this engine.
Would you believe the engine on this beast was designed to run on a 10:1 fuel mix I guess smoke and oil pollution was not too high on the agenda back when these engines were designed, there are conversion kits available to bring the ratio down to 25:1 but not fitted to this engine as it will not get much use and the oily mix has done a great job of preserving it so why mess with a working formula.
