I'm sorry you're so sensitive about this. I wasted at least 2 years tinkering on the two that I had. I'm just telling you the best suggestion I have. I got rid of mine after endless attempts to make them run right. I finally realized that I was wasting my time. I've been running glow engines since '67 so I'm no "newbie". Knock yourself out with the most frustrating cheap engine I ever bought. I apologize. Have fun.
