Briggs 5.5HP - No Spark

I have an older White HW-615 with a Briggs 5.5HP. Cutting the grass and the mower ran out of gas. Walked it back to the garage, filled it up, walked it back over to where I was cutting and attempted to start it back up. Wouldn't start. It was starting to get a little late, so I left it alone for the day. Today I attempted to fire it up again, still nothing. Checked to make sure I was getting fuel, fuel is coming up into the carb when I prime it. Pulled the plug, didn't look terrible, but couldn't remember the last time I replaced it (2 summers ago?) so I threw a new one in. Still no fire. Pulled the plug, laid it against the block and pulled the cord. No spark. Am I looking at replacing the ignition coil? Anything else I should check before jumping to that? Thanks!

Also, tried looking at engine manuals on Briggs' website. It lists an illustrated parts list and 2 operation manuals, all lead to "Page Not Found". Thanks a lot, Briggs... :thumbdown:

If you are sure its not a fuel problem then check the kill wire/switch

Running out of gas doesn't effect spark. Try grounding your plug better. Was the plug wet when you pulled it out? Try a little starting fluid. gregjo1948

Like EngineMan said, pull the kill wire on the mag and then with the plug out, spin the flywheel by hand and check for spark. If you get no spark, you will have to get a new coil, listed in the parts book posted.

Thanks y'all! I'll check this stuff out this evening.

Anyone know what the air gap should be for the coil? Thanks!

I always set it at .010.

Cheater method is to put a standard business card between the flywheel magnets and coil. Let the mags hold the coil in place while you tighten the bolts down. Remove the card and put the blower housing back on.

Ok, so I have the control handle held (pulling the kill switch open), set my coil air-gap to .010", pulled the plug (still connected to the coil) and grounded it against the head and spun the crank by hand. Still not getting any spark at all. I moved the plug around, seeing if I get a better ground anywhere on the head, but still no spark. Safe to say the coil is a culprit?

-See if you can get someone to pull the rope while you watch for any spark. If you still don't see any, it's time for a new coil. You can find them all day long on eBay for about $20. And usually free shipping...

There's a small wire coming from the coil, which is to kill the engine, I believe. Disconect it to be sure it's not grounding the coil. gregjo1948

Thanks, Greg. I'll check that out as well.

When you say older, would it have points and condenser? They would be under the flywheel.

I don't THINK it does. Mid '90's?

Disconnected the coil's grounding wire, grounded the plug and gave the flywheel a spin again. Still no sparky. Coil the culprit?

-Yep. Get the coil # that is molded into the top of the coil and cross-reference that # for a replacement on eBay. Or you could take it to your local shop and see if they have one in stock...

Use the cheater method. Get a standard business card, loosen the two bolts for the coil. Slide the card between the coil and flywheel, then push the coil against it while tightening the bolts. You can also turn the flywheel so the magnets face the coil and that will hold the gap you need as you tighten the bolts.

Matt
