    My 1999 20hp ghs 42" deck walker has not been vacuming leaves like it
    has in the past. It is leaving small amounts of leaves behinb. I have
    replaced the belts and blower housing, and catcher screen and there
    are no clogs. The motor has 1690hrs but seems fine. The deck is
    slightly worn and some of the baffles on it are bent a little. Even
    dropping the deck very low doesnt solve the problem. Also the blades
    are new. Any help would be appreciated.

    Did you replace the blower wheel when you replaced the housing? Also, are the engine rpms the same as before?

    yes, the complete housing and wheel were replaced. Unsure about rpms. What should they be, and how do i test? thanks

    You need an electronic tach, you hold it up to the spark plug wire and adjust your RPM's accordingly. No load RPM's for that mower are 3600.

    If you have checked all of the above....check to make sure that the collection system vents are clean and clear. Air in needs air out......

    Also check the belt tensioner spring for the blower

    this is probably the problem.... the tensioner for the blower is underneath.... or thats how i get to mine... when mine first started doing this i couldnt figure out what it was.... there is a grease fitting underneath thats hard to see unless u get under it.... behind the gas tank... make sure its greased good and working properly....

    Far reach....but there is a 3/4" lip that goes around the bottom edge of the deck....is that worn off.
