I have 16hp single cylinder horizontal B&G engine in my lawn tractor.
(Manufactured in 1976). An electronic ignition had been installed before I purchased the tractor. The tractor ran well for 5 years. I replaced the electronic iginition , a broken wire, and now the engine will not fire. There is plenty of spark, the fuel supply is good and the compression is good. Any suggestions? Could this be related to timing? Thanks Clyde |

Thanks Clyde By plenty of spark do you mean at the plug or off the plug wire. If the later, try the former to rule out a bad plug. Secondly, rule out bad gas as well as the engine getting too much or too little. If you have no signs of flooding - like gas running out of the carb - try resetting the low idle and fast run screws to the basic position. It's the same for both at 1.5 turns counter-clockwise when starting with the screws turned clockwise as far as they will go (be gentle - *don't* crank these too tight or will wreck the needle or the seat). I'm sure you'll get better posts than this from better heads. Best of luck. Chuck |

Chuck Is the plug wet after trying to start it, if so its to much fuel or weak spark, squirt some fuel in the carb and see what happens, maybe the choke is off. |

I would remove the air cleaner, give it a shot of ether( be very
careful about the amount, this can be dangerous) or carb cleaner or a cap ful of new gasoline, attempt to start. If it does not start and run briefly on ether, you have an electrical problem. If it starts and runs briefly, you have a fuel delivery problem. Did you remove the flywheel to replace this ignition thing? There is an alignment key on the shaft that is the timing on small engines, if it has been hurt, it will not start. The magneto must be the proper distance away from the magnets, but you do say you have spark. Remove the spark plug, install sp wire, touch the bottom of the sp to engine, pull the cord. Good strong bright blue spark on the working end of the plug? -- ______________________________ Keep the whole world singing . . . . DanG (remove the sevens) wrote in message oups.com...
