Problem with a 18.5 HP Briggs and stratton engine
Comments (2)Did you try it with the fuel cap removed, the vent may be plugged. Remove the pump and with a finger over the inlet fitting,suck then blow through the impulse hose fitting. You should feel suction on your finger. If not, replace the pump. Probably p/n 808656....See Morewiring a briggs & stratton 18 hp engine
Comments (6)hi all i have a qestion that i hope can be answered. i have poulan riding mower that had an 17 hp i/c single cylinder on it that blew up, my dad had a 18 hp opposing twin cylinder lying around have already bolted the motor on and hooked everything up except the wiring, not sure how to wire it up the 18 has a yellow wire from the coil and the red and white wire from the stator, the mower its self has the same plug for the white and red wire, but is orange and red, also the other motor had the high speed cut off that went to the carbuerator, it is white and black. when i plugged the red and white wire to the red and orange wire together and ran the mower, my key switch would not cut it off. just wonder if any one on here has done this. any info on this would be greatful thanks....See More18 HP Briggs engine problem...
Comments (3)"Loosen the clamp holding the governor arm to the governor shaft where it comes out thru the engine block. Hold the throttle in wide open position, rotate the shaft coming out of the engine clockwise as far as it will go. While holding both in position, with your 3rd hand, re-tighten the clamp holding the arm. There will not be very much movement in the shaft coming out on the engine in either direction." Ok gave this a try and the same problem exists. After the engine is started with the throttle full choke then backed down a bit, the enigne runs great and will run great for a long time. When I try to throttle down to shut the engine off, nothing happens, and secondly when the engine is hot and the load is removed the engine revs want to sky rocket. So I took the engine back off the chassis and took of the bottom of the engine to gain access to the governor/oil slinger. Something just does not seem right. I am not sure where the g/os is suppose to be positioned prior to putting the cover back on, and how much play there should be in the arm that compresses the governor. I have taken a few pictures of the engine and posted them on my website. Just follow the link to see the pictures, once at the index page you can click each picture for a larger view. http://www.jehorner.org/engine/arles_gallery/18hp%20Briggs.html Thanks a million for your help!!!!

Comments (3)"then rev up and down then quit running. " Reving up and down indicates fuel starvation not flooding. First I would clean out the carb float bowl. Removing the hex plug on the lower right hand side of the carb and letting it drain MAY accomplish this. Blow compressed air into the main jet which is located just behind this plug if you have the means. DO NOT do this when the engine is hot or where gas might cause damage to suroundings. A better way would be to remove the top of the carb. This must be done carefully as the gasket needs to come off with the top, it may be stuck alternately to top and lower part and there are at least 3 different variations of this gasket which will be hard to find without buying a carb rebuild kit. Blow compressed air into the various orifices found in the upper surface of the carb bowl, especially the brass looking one after thoroughly cleaning out any foreign material in the bottom of the bowl, water, rust particles, etc. IF this does not help, does the fuel line run through the cooling shroud? IF so, there may be obstruction of the cooling fins causing overheating of that cylinder bank and vapor lock in the fuel line where it runs through the cooling shroud. A temporary rerouting of the line or an external gas tank may help find if this is the problem. Walt Conner...See Morercbe
