I found that closing that gap will definitely help in dry snow. Probably the reason Mfg. are not doing it i cost. They want to make them as cheap as possible to sell and not real concerned about performance. If you have a JD your not going to make a better performing CC thrower work on it as an example.
As long as your engine is strong enough to run a thrower, speeding up the thrower a bit shouldn't make any difference. Mine was on a diesel which performs a lot different than a gas engine. Just don't get casrried away on changing the thrower speed.
