Question about Briggs & Stratton Garden

1 Answer

I have a new leaf bagger/chipper with a Briggs and Stratton 205cc engine. The engine starts normally when cold and after being choked but when the engine is hot it will not start unless it is choked again. What causes this problem?

Maybe an improperly adjusted float level in the carb. Just a bit too low. Every engine has its own idiosyncrasy's as long as it will start again, does it really matter?

Your engine model # 128602 Type 0212-E1. Forget about ordering from Sears and paying shipping and waiting a week. Go to your local Briggs and Stratton dealer (most shops are) and buy part # 694395. Should cost about $3.00

Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please do not forget to rate me, Thanks
Good Luck, I hope this helped

SOURCE: my briggs and stratton 675 lawn mower won't

I am guessing that this is your ENGINE model number: 126K02-0512-B1
Using this reference:
http://www.partstree.com/parts/?lc=briggs_and_stratton&mn=126K02-0512-B1&dn=35820003
Check to make sure that the choke item number 97 is not sticking.
Then remove the float bowl nut and float bowl assy. Clean the fuel passages in the base of the carb with carb cleaner including the area where the bowl nut screws into. There is a fixed jet orifice that must be cleaned in the threaded area. Also clean the visible brass tubes in the top of the carb.
Check fuel flow with the bowl removed. You should have a good fuel flow with the float angled down and as you lift it level fuel flow should STOP. If you do not have fuel flow... remove the float pin, drop the float and needle and celan out the hole where the float needle was. Remove the main fuel line and check for fuel flow. Use carb cleaner in the hole where the fuel line connects. If you do not have feul flow from the fuel tank.. check the tank port and look for any kind of in line filter. If you find a filter... check the line before and after the filter for fuel flow. Once you have established fuel flow Reassemble carb

Check the spark.... if you have no spark
First check the thermostat by just disconnecting it. Item 291
http://www.partstree.com/parts/?lc=briggs_and_stratton&mn=126K02-0512-B1&dn=35820004
Then retest your spark. If you have spark with the thermostat disconnected the themostat is bad. (Most engines use a low oil level sensor..... this one uses the thermostat)
There is an electrical contact on the throttle plate that is grounded when the throttle is selected to off. Make sure the throttle plate lever moves off of the contact when you advance the throttle. ALSO... there is another ground / contact on the engine brake. Make sure that when the engine brake is released that the brake lever moves away from the ignition grounding contact.

The above are the basics.... If after doing ALL of the above you still have problems with ignition then suspect the ignition components.

Thanks for choosing FixYa,
Kelly

Briggs and Stratton intek 900 Series 205cc It will starts but it wont stay running.


The usual cause for the problem you describe is related to fuel/
carburetion. Today's formulation of gasolines have a shelf life of only 4-6 months before they start gumming carburetor. Other forms of fuel contamination (dirt, water, etc) may also be the culprit. First step is to remove and thoroughly clean both the tank and carburetor. Reinstall. Install a small engine filter in the gas line when you reassemble. Use FRESH gasoline after you are ready to start your engine.

Describe your "model number 113.796810" Problem I


Unfortunately this engine has been discontinued. That being said, you can remove the engine and measure the crankshaft. Take the crankshaft measurements to your local briggs & stratton dealer and see if briggs offers a similar engine. My guess is that the engine on your vac uses a short crankshaft. Probably 7/8" by 1.25" or something similar.
Most of the briggs replacement engines can be ordered with onboard controls and gas tank.
Good luck!

Briggs & Stratton Van Guard 16 hp D.C. Chipper with Gravity Flow. With fuel switch on and starting engine four minutes, white smoke apprears and increases gradually, then heavier and chokes itself...


Sounds like your carb is flooding. Inside the carb, there is a simple valve that shuts off the fuel flow when the fuel bowl is full. If this valve fails, or if the float sinks, then too much fuel is forced into the cylinder and will wash past the rings and into the crankcase. This causes the engine to run very rich. You need to remove, clean and overhaul the carb, and change the oil and sparkplug and probably the air filter too. Find the model, type, and code numbers on the engine and go to www.partstree.com , www.ordertree.com , or your local repair shop to get the needed carb overhaul kit. Some B&S engines have an option of carbs, so look for a name on the carb itself...probably Nikki or Walbro. The carb kit is not very difficult to install, but make sure to get everything very clean before reassembly.
Good luck.

if the starter rope fails to retract, then you need to either fix a broken spring, or put a new one in. You'll have to take the engine cover off, and you'll be able to see how to take apart the retractor assembly. Often times, just the end of the spring will break off, and if you have a grinder, you can grind the correct shape in it again, and reinstall it as is.
