adtkart Sounds to me like it just needs a paint job. Usually when they start to rust, they don't run as well. Who wants to push around a rusty lawn mower? LOL

I agree that it may be the diaphram. It also may be the pick-up screen in the tank. They get plugged from all of that garbage, and will not allow the carb to pick-up the fuel. Not much else to go wrong with those things. Last time I bought a diaphram for one, it was about $1.25. Not a bad investment.

grouch It needs chrome rims, some nice flames, a skull shift knob and a couple of STP stickers. The STP stickers will make it run sweeeeeet. For more power, replace the dinky muffler with 2' of 1-1/2" galvanized pipe.

Festive57 I get allot of used mowers, actually they are mowers that people want to throw away. I take them and go to one of the local briggs and stratton reps. and get the same things every time... A $7.00 carburetor rebuild kit and a $3.00 spark plug. It works every time. My suggestion is look around to see where your local distributor is... I was extremely surprised at how many are around once I started looking. I have not purchased a brand new mower for around 10yrs. The first throw out mower I got (an older self propelled) is still going strong (this is after someone put it out for the garbage man... I know, I actually went dumpster diving). You could definitely do what the others suggest and replace the diaphram (that is probably your problem) but at the cost of a full carb rebuild kit... it just runs better all around...

ChevelleSS_LS6 for a fuel tank and carb it was $60 from the local small engine shop. 2 used fuel tanks with carbs (one carb had choke the other had primer) for $7+shipping.

Henry Highrise The carburetor needs the diaphragm replaced.

pigjamelectric Makes a lot of sense. I think I can tackle that.

(It was just oil, no gas scent, still very viscous)

Thanks Hippie, I'll let you know how it works out.

Hippie Sounds like the diaghram under the carb or the carb is bad, that is common on these. They'll start and run on the prime fuel and then die because the diaghram is leaking and they can't pull fuel from the tank. This can be from a bad diaghram, loose carburetor mounting screws or in the case of the newer ones with the plastic carburetors the carb body is warped. That chinsey little carb can run up to $45. I'm looking for a way to convert mine to an older metal carb. I'm having the exact same issue with one of mine and the replacemnt carb on it is only a year old. And are you sure that's all oil in the crankcase? Some of that might be fuel. Check the screws, if they are tight pull the carb look at the diaghram and throw a straight edge across the bottom of the carb. Change the oil too.

small engine lawn mower question

I just got a lawn mower for free. It has a Briggs and Stratton 3.5 horse engine. Problem is, it will only run with the gas that I prime before pulling the cord, then it quits.

There was twice as much oil as there should have been showing on the dipstick. I drained it to the proper level.

Would having run with too much oil be the cause of the problem?

If any of you have some small engine repair knowledge, could you suggest were to start, I'd like to have a go at it.

Thanks.

Paul.
