Question about Craftsman 42" Briggs Stratton 20 hp Gas Powered Riding Lawn Tractor

2 Answers

**Help** I have a Sears Craftsman 18hp Briggs/Stratton riding tractor, about 10 years old. Just put a new battery in last week. Went to start this morning and battery was dead. The red cable that goes to the starter was very hot where it bolts to bottom of starter. Not sure what to do. Could it be the selenoid between the battery and starter or just the starter? Thanks in advance...

First thing to check is the neg. battery cable if it has a bad connection on either end it will make the pos. cable heat up.

Yes it very well could be the starter solenoid, with a digital volt/ ohm meter and the battery disconnected place the positive lead on the positive test lead . With the meter on ohms take the negative lead and touch the frame or engine . This will confirm weather or not you have a short to frame. If the meter reads 0.00 disconnect the starter from the system by removing the positive and ignition wires from th starter . Now individualy test each wire removed from the starter in the same process as above if ohm meter read ol ( over limit) the starter would be the best place to start. If the meter reads 0.00 would suggest there are other issues in the circuit and the starter may not be at fault.

lift your seat and look at the label that you got your model number from. to the right of the model number is the serial number. the first six digits of the serial number is the date your tractor was made - for example: serial no. 060802D002756 would make the unit made June 8, 2002

My name is Dane and I am going to help you solve your problem.
Your problem stems from a float valve needle that either has gotten a piece of debris in between the needle and the seat, or has gummed up due to bad fuel. This allows the carb bowl to overflow and actually can allow fuel to bypass the rings and get into the crankcase, mixing with the oil. To verify this, remove your dipstick and check the oil level. If it's high then you have this problem. Also you can check and see if the oil is extremely thin or may have a gas odor to it. If any of these problems are found, do not run the engine. After this problem is corrected you will definatly have to change the engine oil.
Now, to your main problem. You are going to have to remove the carb from the engine. Pay close attention to how it comes off and maybe draw a picture if you need to. Now you have to carefully remove the float bowl. There will be a pin that holds the float onto the carb and it needs to be removed. Be careful not to bend the float. Pay close attention to how the float needle connects to the float. Next spray Carb cleaner into the hole where the float needle goes into and any other dirty areas. You should not spray carb cleaner on the rubber o-rings or gaskets.
Once everything looks nice and clean, place the float needle back into the float and set the complete assembly (needle first) back down onto the carb and insert the pin.
If any gaskets are torn or worn, replace those also as you put the carb back onto the lawn mower. Check your fuel hose for cracks or tears also. When you connect the fuel line, check to see if fuel still flows as it did before. If not, change the oil, you're done! It could take about 3-4 minutes for the Carb Bowl to fill with gas before you see it running out.

Well, I hope I've helped. If you found this information useful, please leave me some THUMBS UP if you think I'm deserving! :-) Thank you! Dane

Sears YT 3000 42" 21

oftentimes the things will not start after sitting idle all winter as last year's gasoline has turned into a lacquer which has blocked the flow of fuel through the small passages in the carburetor. there is at least one product, called Stabil, which you dump into the gas tank which precludes this. So maybe a carb rebuild and clean out is in order; and if it then works OK you should make a point to put some of that stuff in your tank at the end of the season. Works well for RVs also.
