SOURCE: I have gas going into my oil. 17.5 Briggs solenoid on carb bowl

The problem is the float needle and seat are leaking. It is not shutting off the gas when the bowl is full. The bowl fills up, then runs down the intake through the intake valve into cylinder, past the rings into the crankcase. Fairly common problem. Just replacing the rubber tipped needle probably will not stop the leak. The pressed-in brass seat needs to be pulled out and a new one pressed in also. Possibly there is some trash or rust in the carb that has gotten between the needle and seat, but in my experience, it usually takes replacing both to fix.

SOURCE: Lt1000 18hp Briggs and Stratton

Go to your local auto parts store and buy an inline spark tester if you don't have one.

Next time the engine stalls, use the inline tester (goes between spark plug and plug wire) to see if there is spark. If there is no spark, then most likely the engine has overheated the ignition module. Check the oil level, low oil level will cause overheating. Check the cooling fins, clogged fins will cause overheating. The ignition module will need to be replaced for a long term repair. Make sure to correct any overheating condition also. When/if you replace the module, it is a good idea to inspect the flywheel key. It is located under a very large nut on top of the engine. If the flywheel has rotated on the upper crankshaft, the flywheel key (aluminum) will have been damaged. This also can cause an overheating situation.
Good luck!

SOURCE: How do I wire a 18hp Briggs & Stratton engine to a craftsman GT5000 lawn mower

I dont have all your anwers. In my experience, Kohler frequently has wires to start, run and stop the engine. They also frequently have a low oil and/or high heat control (engine shut down). Also expect a wire from the charging system. On your tractor, you probably have similar plus 'operator presence' wires. These wires require to you to be sitting in the seat for the machine to operate - a seat switch for example. On my tractor, I can depress the 'brake' (which isnt exactly a brake in fact) and the engine will run when I dismount. However, if the mower is engaged, no matter what, if I get off the tractor, the engine shuts down.

You will have to determine what every wire is for and connect it properly. You may lose some engine 'functionality' or tractor safety features. It is never easy to put a Ford starter on a Chevy. Good luck with your project.

Thanks for your interest in

Have 18hp briggs on snapper zero turn lawn mover was mowing lawn heard bang like I hit a branch and motor slowed down and kept running but ran a little rough no grinding or nokeing engine still runs

This sounds like a burned or stuck valve. Try a little marvels mystery oil in the dead cylinder to see if it can free up the valve (if it is stuck).

What would make gas flow out of the spark plug hole on a briggs and stratton 18hp ohv intek?

If you are getting that much gas out of the cylinder you most likely have a stuck fuel float valve or the float itself is damaged in the carburator. Make sure you check your crankcase for gas also, usually when a float valve sticks it also fills up the crankcase with gas. Hopefully you just have some debris caught between the needle valve and seat that can be blown out. If not replacing the needle valve and seat or float is relatively inexpensive.

I have a 2010 MTD Yard machine 21 inch snow thrower {123cc} and it broke a valve tappet bolt.I need to no were to set the intake and egzaust valves clearance.Thanks!

I can give you Briggs and Stratton figures for valve clearances of an engine this size. You may have to experiment a little till it runs right. can adjust the intake valve (when it is closed) while the exhaust is open and adjust the exhaust valve (when it is closed) while the intake is open if you can tell...or ya can adjust them when the piston is at TDC on compression stroke (both valves closed). Intake: .004"-.006" Exhaust .004"-.006" (Vertical crankshaft)....for horizontal crank .004"-.006" Intake.....Exhaust is .006"-.011" Hope this helps . Here is a briggs engine specs chart..can';t find the Chinese engine listed anywhere

18hp twin cylinder Briggs & Stratton backfire

Check to see if the carb is clean, if so the anti diesel value could not be working. Apply 12 volts to value and see if it move's. If that works then you may what to check the fuel pump and see if it pumps. After you tried all that then you may have change the main jet size because these engines come with a small jet for the EPA.

18hp B&S wont slow down no matter where

It's one of two things. Most likely, the screw(s) have come out of the butterfly valve on the throttle shaft and letting it run wide open. The second thing is that the governor gear inside the engine broke. Unless you a pretty good mechanic, I'd recommend taking it to a shop. If it is just the butterfly in the carb, you still have to deal with...where did the screws go? They may have passed through the intake and exhaust valves or they may be stuck in one of the valve seats or embedded in the piston. Like I said, better take it to a trusted shop, if there is such a thing, unless you live close to me. lol.
