3.5 horse Brigs repair help!
Wayne,
Noted your post B&S engines and I'm in a similar situation. Bought an edger at a garage sale, had corrosion in the fuel tank from sitting too long without being used. I cleaned out the carb, replaced the fuel pick up and diaphram but it still won't run and I can't find any more jets to clean! Noted your comments about the fuel tank (I have the small tank - 1 qt) having the duel level and bowl inside the tank. The bowl is there but corroded. I can't see any fuel pickup that would fit in there so I wasn't sure of how it worked. Am I missing something? I'm guessing I need a new fuel tank. I'll strip out the carb again and maybe take photo's - there's a steel pin (?) about 1" long that I don't understand, it's not listed in the part list. And what's a "welch plug" p/n 223472 - are the main jet's in there? Thanks for any assistance. M - Houston, TX My dad bought a sprayer with a 3.5 horse engine at an auction. I have been trying to get it to start. I can make it run for a few seconds by spraying starting fluid down the throat of the carborator. I took the carb off, it has a plastic tube with a filter on it going into the tank. I cleaned this tube and sprayed cleaner through the carborator. It did not help it to start. I have put a new spark plug on it also. Is there an adjustment on the carborator I can make? Any help would be greatly appreciated! |

Before any more work, just get the choke closed and put a pretty liberal supply of gas on and around the choke plate and try to start it. If you get nothing after a couple of pulls, it isn't a fuel system problem. Don't assume that the corrosion indicates it is entirely a fuel problem. Many of these small engines have magnetos die on them, and they still may produce some small spark when you try to test it, but it won't jump the plug gap under compression. Jon |

Been in the exact same position recently. My father has a tiller with a B&S 3.5 that we could not get to run. It had been difficult to start for a few years but got to the point last year where it wouldn't start at all. There was a problem with crud shorting out the ignition kill contacts a few years ago but it had plenty of spark when I decided to have another go at it last month. Tried carb cleaner, tried cleaning the fuel pickup, tried tightening up the connections from the crankcase to the fuel pump, tried cleaning all the crud out of the fuel pump- nothing. It would run for a few seconds on quick start but that was all. Finally I took the jet out of the side, seemed clean but I ran a wire through it just for fun. Then I shot compressed air into the jet passage just for luck & put it back togeather. Started on the first pull. Tweaked the idle adjust a little & it runs like new .

Jon A couple of older B&S I came across, had the points actuated by a plunger that rode the cam on the crankshaft. This plunger was stuck in the open position, once I got this freed up the engine started and ran great. Gerry :-)} London, Canada |

Thanks for the responses.
Let me give more details. The engine fires up fine when I put gas or carb cleaner in the carb intake and I can keep it running by continuing to feed it manually. I have a camera but the link is at the office. I've been to www.briggsandstratton.com and downloaded the parts list - have a look at the pdf file at http://shop.briggsandstratton.com/BS...ngineType=2288. The engine number is 80202 2288 88071903. The machine was new in 1989. Wayne: I think its the newer style of carb but it just has a plain spring loaded jet. Appreciate your thoughts. M - Houston. |

Wayne,
I can't get photo's but here's a link to the illustrated parts list - http://shop.briggsandstratton.com/BS...ngineType=2288 The edger was new in 1989. I belive it's the newer style and has a spring tensioned jet on the side - the oppostite side to the diaphram. I replaced the diaphram and cleaned out all the holes with carb cleaner. It runs when i manually feed fuel into the carb. Wierd, that's why I wonder about the wier in the tank. Thanks. Mike - Houston. |

Mike - Houston. make sure the tank is completely topped up when starting, prime, start, prime start, prime start, until you get it going or fall down. it should get plenty of priming so it really takes off then dies. if you flood, it it just take a few pulls to clear it w/no aircleaner --Loren |

It's just that I've never had to buy anything other than filters. Funny post, though. My experience with BS engines has never been anything but sorrow, regret, and grief.-Jitney |

The carb I have is exactly as you describe and I have two problems to be fixed. 1, the fuel bowl in the tank needs rebuilding and 2, the main jet is blocked and I may have to remove the welch plug to get at it. The jet itself is exposed on the side of the stem. It takes a pretty small wire to poke through it. My preferred jet cleaner is a single strand off the kill cable of a old lawn mower. I've contacted Seal-All and Walmart should sell it. I'll put off the carb, soak the lower appendage with the main jet in release oil and repair the tank while it soaks. If I can't get the jet clear I'll remove the welch plug (drill a small hole and prize it out) and attack it that way. If there's a lot of corrosion the welch plug may of rusted through and need replaced anyway. The jet is easy to clean but sometimes the tube going up gets stopped up. What would be my chance of finding a used tank in good condition?? That's a somewhat rare tank being so new. I know that I've not got one but you might try a few small engine places and see if they've got one. A new one could be ordered from Briggs but I'm not sure what it would cost.

Wayne,
I hope by the time you read this the B&S will be purring like a kitten. I found and cleaned out the jet (cleaned it with a pin and can blow through easily). I took out the bowl and repaired it with seal-all. Leak tested it this morning and all OK. I'll flush the tank with clean fuel, put it all back together and cross my fingers (i'll fill the bowl too..). More soon. |

Yea ha!
We have a 3hp B&S up and running. Did the repairs as discussed - filled the reservoir with fuel, installed the carb. One shot of carb cleaner and fired up first time. Took her out and did the edges. Great. Checked yesterday. Fired up first pull. YEA HA.... Wayne you're a gem - couldn't have done it without you. Thanks very much for your help. M - Houston (the house with the nice edges...) |
