Question about Sport & Outdoor - Others

Open Question

I have a weedeater mower with a Briggs & Stratton 4.5 HP engine. The engine's model number is 10H902, type 0333 E1, with a code 05092754. My problem is that I can't even get it to start, before it would start, but run rough. I changed the spark plug with a new double platinum plug, which still fouls out, I also replaced the air filter with a new one. This model does not have any throttle control, according to Briggs & Stratton's website, my engine has an atmosphere controlled throttle & choke. When I pull the air cleaner off, I notice that the linkage justs flops around, basically letting the choke flop open and closed. Is it just in the springs or is there something on up the line, ex. atmosphere control device, that is causing the throttle control problems?

I always replace the air filter if its a paper element, and even if its a foam element I replace it rather than clean it. That said, engine stumbling is rarely and air flow problem - but it could be, so having a new filter assures no air restrictions.

I would drop the carbuerator bowl. On the bottom of the carb, near where the fuel line comes into the engine, should be a nut. Removing this nut allows the bowl to drop off the carb. Some engines the bowl screws off, you will have to look at the bowl. Often the bowl has sediment or sludge buildup inside. Cleaning the bottom of the bowl can prevent that sludge/sediment from plugging the intake tube. Even on newer mower models this is a common problem, the gas line tubing interior breaks down and the inside of the tubing can start degrading - ending up in the bowl as sludge.

After cleaning the bowl, I would add one ounce of fuel line cleaner to a full tank of fuel and run the entire tank of fuel. This will clean any deposits or "varnish" from the interior carb parts. Doing this and the first step will assure your carb is clean and functioning.

If that doesn't help, then I would look at the spacing between the magneto and coil assembly. If you want to do that I'd like you to write down all the model numbers and serial numbers on the engine nameplate, that way I can give you specific directions.

Hope this helps,
Gregg

The easiest thing for you to do is look at any 12.5-19hp Briggs single cylinder engine that's on just about any riding mower.. They all have the same set-up.

Need repair manual for briggs and stratton 4.5 hp on bolen lawn mower model 11a-414e765


After a very extensive cross reference session your engine is model number
10H902-0285-E1 (not provided by you so it took a while)

Your engine is covered in this repair manual:
http://www.mymowerparts.com/pdf/Briggs_&_Stratton_Service_and_Repair_Manuals_Spec_Charts/270962%20Single%20Cylinder%20L-Head%20BRIGGS%20&%20STRATTON.pdf

If there is a problem that your having I can help you if you would just elaborate. I could save you lots of time. The 2 most common failures of this engine is on the carburetor. The parts that fail are the diaphragm (Item 394) and the primer bulb (Item 976) of this link:
http://www.partstree.com/parts/?lc=briggs_and_stratton&mn=10H902-0285-E1&dn=57160004

Carb data is in section 3 of the first link.
Thanks for choosing FixYa,
Kelly.

Hi i would like a diagram to show valve timing with crank shaft for a briggs and stratton 3 hp petrol engine


"3 HP" means nothing. For definitive, need the Model, Type and Code numbers off the engine. But probably 90% of Briggs engines or better are timed with the valves closed at 1/4 turn past TDC.
