Hi brockjeep and welcome to TSF,

How did you check for no spark? (sparkplug laying on the block with a plug wire connected to it?) Look for a strong blue spark. A weak redish spark will sometimes not fire the cylinders and it might be thought there was no spark.

Does the engine turn over strongly, or draggy? Note that when the starter is engaged, there must be over 9 volts at the battery terminals in order to get spark. If the starter pulls it down below 10, you'll probably get no spark. If you have a volt meter, check the battery voltage during start.

If you have electrical prints of the ignition system, you might post it here and we can help you troubleshoot the problem.

Very best regards,
Mack1
