Summer blend gas and Briggs carb seals???

1936 · Oct 31, 2008

I have been told in the areas that require summer blend gas which I am one causes the Briggs seals to soften and gas to leak down into oil??? Have a 17 HP Briggs and is doing this. Was told to install an inline gas shut off and a new gas cap???

Never heard that one??You might have a needle & seat not closing or a defective or out of adjustment float.Of course a cutoff would solve the "leaking"to carb.bowl,but it's not the problem."Always use an inline fuel filter".I would ck the above first.Let us know what you find.Dude11

The seasonal blend makes no differance, what is making this happen is the ethanol fuel you are using. It is hard to find fuel without it, but that is the main reason. The best thing to do is put a shut off in the fuel line and don't worry about it. You can rebuild the carb with a new needle and seat every 6 months and it will happen again.

JT,I'm not sure what % ethanol is in his fuel?We have had 10 or 25%mix at our stations for some time and I've not had his trouble,thank goodness.Maybe the mix is different from state to state.I'm located in Ga.Dude11

Dude, this is quite a big problem around here in Illinois. We get machines in all the time that the rubber needle is all messed up from the alchohal. So, you are a very lucky one.

Don’t blame it on the gasoline.
I have a Husky #44 chainsaw ( high end Electrolux) built back in the early eighties. I’ve run every kind of gas there is in it. It runs great and I have never had any trouble with the fuel lines. The saw was built to industrial specs. I have recently resurrected several late model Poulan ( low end Electrolux), and Briggs engines for friends which have all had fuel line problems. The plastic gets brittle or gummy and just disintegrates.

My opinion is that to make them cheaper, manufacturers are using cheaper less durable plastic fuel lines especially in the lower end machines. It’s a foregone conclusion according to the retailers, that when the thing won’t start, the easiest thing to do is go buy a new one. I for one, think this is really wasteful. New gas line is cheap and really how much are they saving by putting in cheap lines? Not much. It’s a guaranteed obsolescence thing.

Quantity over quality every time. Good for Biness

Shaking my head no.
