    Need Factory Spec RPM Speeds Briggs and Stratton 9D902 (92000 series)

    Tab on lever hasn't been modified - it's just the way it was when it left WalMart 20 years ago when new. Good memory - the owners manual states "On *some* models the governor lever is bent into position and is not adjustable" and points out the "Governor Control Lever (if equipped)" in an...

    Briggs and Stratton 3.5hp Classic: Plastic 'Upgrade' Air Filter vs Metal Air Filter housing for Dusty Conditions?

    I goofed above - it was St. Augustine grass I put in that plot NOT Bermuda. I spread a little soil on the sand and laid down St. Augustine sod.

    Need Factory Spec RPM Speeds Briggs and Stratton 9D902 (92000 series)

    Interesting - thanks. The engine above has a lever with a 'detent' at each extreme so I guess I'd call it a 'two speed'. But definitely no 'idle'. Those old L-heads weren't the cleanest I guess and this must have been a way to milk a little more productive life out of the line before retiring...

    Briggs and Stratton 3.5hp Classic: Plastic 'Upgrade' Air Filter vs Metal Air Filter housing for Dusty Conditions?

    I put a green flanged filter on oiled lightly with tacky bar/chain oil. It's both snugger inside the canister and provides a 'seal' around both the top cover and the base. It is likely to 'tatter' at those flanged edges over time however. But, when intact, I suspect it's a superior seal for...

    Need Factory Spec RPM Speeds Briggs and Stratton 9D902 (92000 series)

    From what I can tell - due to the lack of range of movement in the OE governor lever on the engine - there is no meaningful way to adjust the slow/idle speed separately from the fast/run speed. With the single effective spring - there is a pretty consistent 400-500 RPM gap between slow and fast...

    Briggs and Stratton 3.5hp Classic: Plastic 'Upgrade' Air Filter vs Metal Air Filter housing for Dusty Conditions?

    My B&S 92000 series 3.5HP Classic in a basic Murray mower has the old school metal can air filter housing. It uses the 'flanged' green-ish foam air filter where the flanges on the foam help seal around the lip of the air filter housing cover (and the plastic 'cup' inside) to form a gasket when...

    Need Factory Spec RPM Speeds Briggs and Stratton 9D902 (92000 series)

    3,200 - thanks! ;) SLOW/IDLE: I need to figure out why it's slow/idle speed is way too high still (without messing w/ the full/run speed). :unsure:

    Need Factory Spec RPM Speeds Briggs and Stratton 9D902 (92000 series)

    I have a basic Murray 20 in mower with a Briggs and Stratton 9D902 3.5 HP 'Classic' L head. It is a 'throttle free' model - ie. no throttle on the handle bar just down on the motor itself with 2 settings. Lately the RPMs seemed kind of high so I checked it. In the low position it is 2,750 and...
