Need Pro's Opinion

Hi Guys, I need an opinion on an old briggs in an old Sears tractor. It's a 325431, 0139-01, & code 7202281. It's been sitting, & I've cleaned the fuel tank & carb in a bath & installed a kit & float. It runs strong for 5-8 mins than I loose spark. It's very intermittant after that, but strong blue when it does spark. I'm using an air gap tester & the kill wire is off. Does this sound like a condensor issue or more like a coil?? The points appear clean, but i think I'll get a tune-up kit Mon. Try it or think I should get a coil too??

Thanks in advance, Roger

I would start with a points and condenser kit. The ignition coils seldom go. If you have disturbed the coil at all, make sure the flywheel to coil gap is .010 or so.

On very rare occasions coil wiring separates when warmed up and spark is lost. I only see this about once every five years or so and isn't the first thing I would be looking at.

I'm not at my shop to reference my service manuals, but I believe that this engine has a rather complicated ignition coil timing procedure involving both the coil mounting bracket as well as the flywheel retainer. I'd recommend starting with the points and condensor replacement as backyard indicated using Briggs points part number 298185 and condensor 298060. If you have never disturbed the coil bracket (timing) and you still have no spark or weak or intermittent spark then the coil is part number 298968 but don't mess with the timing if possible.

Thanks, Guys. I haven't gone anywhere near the ignition coil yet, just pulled the cover from the points to take a look.I kinda thought maybe a condenser going out, but always helps to have other opinions. Thanks for the help, Roger
