Depending on what machine the engine is fitted to, check the regulator rectifier is working by checking the voltage going into the battery while running. If over 15v then try replacing reg/ rec unit. I had one recently doing this, and as everything electrical ran through the PC board when there was an overcharge on the system the PC board would shut down the machine
To save the electrics being fried
This model has both fuel pump and solenoid. Make sure carburetor mounting bolts are not loose. Check that solenoid is not sticking and open full.
I'm not sure how low the fuel tank is relative to carb. If you can get enough fuel in the tank so the fuel level is higher than carb and it runs ok, then likely a fuel pump issue.
How long until it dies? is it very consistant? like every 40 seconds
i would try losening the gas cap and see if the stalling stops. might be that the gas tank vent is clogged.
SOURCE: is there an oil filter on a Briggs/Stratton riding lawn mower. Model#42A700
Yes there is a spin on oil filter. Depending on the date code when the motor was built there are two possibilities. The easiest way is to measure the length of the filter, If the filter is 2 1/4" long the Part Number is 492932.
If the filter is 3 1/4" long, the Part Number is 491056.

Hi did you squeze excess oil from filter so it can **** air in??
SOURCE: Briggs & Stratton Briggs Stratton Intek V -
these are common for doing this ,if you dont want to pull it down and hone the cyl. then i would use a heavier oil say 20w/50and that will probabley solve your problem

Rex,
When you installed the new ring gear and put the flywheel back on, did you use a new flywheel key (Briggs recommends using a new key anytime you remove the flywheel) and did you torque the flywheel nut to 85 ft lbs? If not, that is where you need to start troubleshooting. Remove the nut from the flywheel and observe the key and key ways making certain that the key ways are exactly aligned.
If they aren't or you can not see them very clearly, pull your flywheel and inspect the key. If it is damaged at all replace it and be sure to torque the flywheel nut to 85 ft lbs.
Did you remove the ignition armature (the coil) when you removed the flywheel? If you did, did you set the air gap to the proper specification? It should be set between .010 and .014 (ten to fourteen thousandths)
Did you tighten the screws that secure it to the engine good and tight?
Check all of these items first and if you don't find anything obviously wrong, get back to me and I will see if I can help you further.

Testimonial: "Chuck, You were spot on, the key was sheared off.Replaced key&retensioned flywheel nut. Whacko she fired up. TKU for your great advice & support."

You should be safe with a 10w-30 weight any major brand oil.
