Billy Goat LB30 / Briggs & stratton 92501 questions


Picked up a very early Billy Goat garden vac, early 80's I think. The engine starts on the first pull, and runs perfectly with a satisfying tone.

I have never owned a petrol engine other than my car, so I don't know the general maintenance /usage facts. I would like to know how best to maintain it and also how long it will last if looked after.

I know it's a 4 stroke engine, and I have found the fuel tank. What I'm unsure of is how and where to top up and check the engine oil.

I haven't found a manual online for either the Billy Goat or the engine, so any links would be appreciated.

Billy Goat: Little Billy LB30

Engine: Briggs and Stratton 092501-1009-01, 158 CC, 3.0 HP

Welcome to the forums!

Normally there is a little plug near the bottom of the engine, you remove it to check the oil [it fills to the top] Normal maintenance is fairly simple; change oil, spark plug, clean air filter, don't leave gas in the system for extended periods of non use [like over the winter] without adding something like StaBil to the gas. The small engine mechanics should be along later with more/better info for you. One of them might even be familiar with your particular machine

The Billy Goat website has a list of downloadable manuals. I did not see your model listed but looking at the other LB manuals should give you most of what you need.

Thanks for the replies.

The closest manual to mine is the LB351, which does actually resemble the one I have.
Even in that manual, they do not describe how to check / top up the oil.

The engine though is where the main difference seems to lie.

The LB351 seems to have a throttle marked with fast and slow settings, and a push button primer. The LB30 has only a knob saying start / run / stop, which seems to be the throttle control.

One of my other questions is with the motor I have, is it OK to run it in the 'start' setting. This seems to be full throttle, and gives quite a bit more suction than 'run'. I don't mind the extra fuel, but don't want to burn out the engine.

Full throttle ok with these things?

I have been using the vac for a bit now, and have found where to put the oil, seems to run really well and does a nice job.

My only remaining question is a general one really: can I run this old engine at full throttle without damaging it? Full throttle is 'start' on the dial, while 'run' is a lower setting, with noticably weaker suction.

In case you haven't read the original description, it's a 20-30 year old engine.
