Jake0030 47 #1 Posted August 5, 2019 So I posted a thread in electrical because i thought that was the problem, but it wasn't. After bogging the mowing deck with a big stick, she refused to start. Turned over, but wouldn't start. Apparently there is some thing called vapor lock. This is apparently when due to high temps an air bubble forms in the gas line or carb. The fix on my 312-8 was a simple one, remove air filter and hold gloved hand over carb intake. She started right up. Hope this helps some one else. Share this post Link to post Share on other sites
