    Yes, the symptom will be a motor that runs like crud, or stalls out with the cover on, but cleans up and runs OK with the cover off. There is usually a blackish coating on the cowling insulation foam as well.
    Please don’t let test tanks fool you though. This engine is likely to suck its own exhaust when running in a tank because it sits down so low. You sure wouldn’t want to pull the engine apart needlessly.
