hi all i'am new to on road runing offroad for many years.just put a new
novarossi ins box and filter on my 21 keep on used novarossi air filter oil
and ran about 1/4 gallon fuel on track.on inspection the air filter has let
some dirt through into the carb (more than a offroad filter would runing
on dirt) and engine compresion has droped off some.am i doing something
wrong or is this normal for the small onroad filters?
