Russ is pretty thorough and a real professional, but I hate to see a customer with a unit not running. Do you mind if I ask a few questions?
Is this a Briggs Overhead Valve engine?
Is this your generator?
That has a 10 HP Briggs and Stratton Overhead Valve engine. If it's a problem with no spark, we can probably locate the part you need for it.
First, have you tried it with a new spark plug to make sure it's not a bad plug?
Are you comfortable with doing a bit of troubleshooting?
Also, on the metal shroud covering the engine cylinder tere will be three sets of numbers I need, please. Model, type, and code. Will you include them in your reply please?
Coleman doesn't provide information on the engine, so I'm not sure which one you have, but I'm supposing you have a model 204412 of some sort.
What you are describing sounds like a bad ignition module, a common failure. To be sure we need to do a bit of troubleshooting. Do you want to proceed?
