I thought the article was so good, I saved it on my computer. As you guys know I battled with my HPMX carb this year. I had two main issues that cause problems. The first was a vacuum leak at the manifold. The second was a bad Magna Spark Coil. These two issues made me think the carb were the problem. I chased these around for two months. Removed and cleaned the carbs three times. The HPMX carbs are a good product.
