| Sounds like its flooding and when it sits the fuel evaporates and it will restart. Check to to be sure float,needle and seat are working properly. Does it smell like gas? | |

| Don't guess, test. As soon as it quits, do a spark test. If there's no spark, your coil is shot. It is very common for a coil to refuse to work once it get's hot. Bad winding. | |

| I'll take a swing at this one...
I'd bet it's the solenoid on the bottom of the carb bowl... If those are stuck, the engine will run until the bowl's empty, and then die. Take a screwdriver or something and tap on the side of it several times and then try starting it. | |

| when it doubt, check it out, check you float, I've had them bend enough to flood em out. Also, check your valves by pulling the sump cover if the compression is low. If the valves check out, check your head gasket, generally if its not blowing air out of the side, it is okay, If compression shows up good, check spark (i would actually check this first), you can do this by pulling the spark plug off and grounding the plug on the block and turning it over and watching the plug. Don't be a numb nut and get zapped... An engine needs 3 things to run, fuel (gas/air), compression, and a good spark. Your problem could always be the spark plugs. I've had numerous engines have issues and the problem was the spark plugs... | |

| ive never ever ever seen a oppy with a screw on the bottom because the whole carb pretty much is the bowl to open it there are screws on the top that remove the top plate that allows you to pull the float out | |

| I don't think it has a low oil switch, but there's an easy way to rule it out. Locate the wire for the kill switch. Usually yellow, and exits the engine under the flywheel from the coil. Disconnect that wire. Attempt to start engine and/or check for spark. | |

| I do still have spark with that wire disconnected and I was curious on the heads I took the tins off and tried the bolts and was able to turn them about a quarter turn with out forcing them so I dident strip them and I checked the compression again and the low side went up to 50 and the other side went up to 80 what should it normally be at | |

| Briggs does NOT specify a compression figure, possibly because of compression relief mechanisms, etc. They do spec a comparator on the twins- the low cylinder must not be more than 25% off the value of the high cylinder. | |
