I am the new owner of a 1995 Gold-series 5 HP self-propelled mower.
The throttle has little affect.
There does not seem to be a full throttle RPM increase.
The owners manual does not talk about the carburetor or the high speed needle.
It must have one.... Any advice?
The electric start does not work either... Another project....
Might just be a battery..... Also missing the charging cord.
But the rpm increase is the biggest issue.
Thanks, M

check to see if the throttle shaft is binding, i've seen this when the carburetor mounting screws are over tightened, may also want to check if the governor spring is still hooked up to the lever:wink:

And there's also a thumb wheel directly under the governor air vane. Turn clockwise to increase rpms. You'll hear and feel it click. Good luck
Re: No High-Speed RPM... only a small increase from idle...
Well, I took cover off the 5HP gold-series and looked at everything... I still can't find the high speed screw... After re-reading the previous post... I need to back and look again at the plastic "wheel" under the vertical fin that extends up into the flywheel area. The plastic throttle mechanism does not appear to be connected to the vertical fin... The vertical fin is somewhat spring loaded... Throttle movement from idle to full throttle only varies the RPM by about 300 RPM...... It needs another 500 RPM increase. Still not finding anything in the manual or online. Thanks for your help...

Post up the engine/type number and I'll have a look into it.

There's no high speed jet, only air/fuel ratio. The wheel you referred to is connected to the throttle lever by a spring that winds inside the wheel itself. It may be disconnected.
Well, I guess I need to take it back a part and see if there is a spring..... Does the carb have to come off or just the gas tank /shroud?
It is a Lawn-Boy -Gold Series - Electric Start, Self-Propelled walk behind mower. Model Number #10546, S/N 7905773. 5HP....
Separate question... The battery is dead... is there a separate cord to charge the battery or do you have to buy a new battery. It starts easy, but nice if it worked for my wife.

Take the battery off and try and charge it, if it hold's charge it's ok and if not then buy a new one.
is it a B&S engine..?
I have not found a plate yet.... It is a greasy mess.... so not sure what the mfg is... The battery has 6 individual cells... Is it a 6 volt? Can I just use my automotive battery charger?

It's a lawn boy F series 2 cycle engine. I once had an identical model. The battery wiring has a place to attach a charger that plugs into the wall. They can be found on eBay. You will not have to remove the shroud to remove the carb. Just the 2 screws and fuel lines.

Its not a 6volt battery six cells around 2volts per cell=12volts, and yes use your automotive battery charger but set it for 12volts not 6.
