Hey all RC fans..I know when you have your engine out of your car,truck,buggy you might want to try this...I know air filter can get in
the way at times...So take off the air filter and put in it''s place a foam ear plug..put it right in the carb opening..it will do the trick for you ..No matter if your
cleaning the engine''s out side case ..or what your doing it will keep crud from getting in the carb and into to engine...Just my 2 cents worth
