Question about Craftsman Garden

1 Answer

Somebody gave me a Craftsman lawnmower with a B&S 7 HP motor, YBSXS.1901VE 275078, because he couldn't get it started. I put gas in and it ran out of the primer bulb so I replaced the primer bulb. Now it's better but still leaking gas. I wouldn't assume there would be gas present in the bulb or at least some kind of check valve in place. I can't find a parts breakdown for this model to see what is in the carb. Can you give me some advice please?

Under the carb is a metal bowl. This bowl houses the carbs float attached to a needle valve. This valve is probably stuck open due to corrosion or dirt blocking the opening. You can remove the bowl with a half inch wrench and lower the bowl from the carb. Let some gas flow out of the needle valve and work the float up and down to help clear out the obstruction.

Push up on the float and see if the fuel flow stops. If it does you can put the bowl back on and see if it stops flowing out the primer bulb.

If it is still flooding you probably need to replace the float, and needle and needle seat. These are pretty inexpensive you can order them online *(ebay might even have them!).

You might want to clean the main jet too. You should get this carbs diagram to show you where the main is located.

My craftsman gasoline lawnmower will start when primed run less than a minute then cut out . how do I determine the problem...then fix it


Have you checked the fuel supply first. Its possible your jet valve may be plugged or dirt in the fuel bowl. One quick way of checking this is take the spark plug out and put a little shot of gas in the spark plug hole then reinstall the spark plug and put wire back in place and try to start engine. If it start and revs up for a few seconds till the gas is burnt up then stalls it is pretty certain its a dirty fuel jet or dirt in the fuel bowl. This quite often a real cheap fix .

My craftsman riding lawnmower cranks over strong but will not start


Do you have spark? There are two things to look for when any engine won't start....fuel & spark, Take your plug out and lean it up against the metal of engine...turn it over and see if you see a good blueish spark.

No spark? Could be the plug, safety switch, coil

Next squirt a little gas into spark plug hole, replace the plug...will it fire up? If so...start working your way back down the fuel system....carburetor, fuel lines, fuel filter and gas (is gas old or new? is there any water in it?)

try that...www.nnyparts.com

Crafsman Eager 1 6.75 HP lawnmower wont start


I have an Eager 1, as well and when I try to pull the cord it does not turn at all. It's stuck. I hit a tree root and since then I have had problems with it. I have 2 mowers so it was not used last year at all. Gas was drained and it was stored in a shed. Anyway, I know nothng about mowers other than spark plugs, gas, oil, sharp blades and filters. Is the motor seized? Thanks
