MMI Week 2 (Post test)

I got a 92. It's not as good as I'd hoped but it is what it is. I missed 4 out of 50 questions.

One question was on being able to identify which parts of a cast iron valve are commonly Stellite plated. The option I chose was "tip and stem" and I only picked that one cause the only other choice that I thought that could have been it was "tip and face" and I could have sworn that the stem needed the extra protection too but I was wrong.

Another question I got wrong was about how many times the camshaft turns to every turn on the crankshaft and piston strokes.....I said 2 cam turn to 1 crank....not sure where my head was on that one.

Third one I got wrong was just identifying the parts of a valve. This is the one that I just checked the wrong box. I got cocky and was going a little fast through the test at this point and just screwed up. I told myself to go slow through it so I wouldn't do this sort of thing but.........well. Lesson learned.

Fourth one I got wrong was "which of the following using mechanical method to move the valve" For some damned reason, probably the "going to fast reason" again since it was the question right after the 3rd one I got wrong, I just read it as saying "which of the following doesn't use mechanical method".

It really sucks when you're going over what you got wrong and you know the reason you got it wrong wasn't because you didn't know the answer but because you just screwed up. I think it feels worse to get it wrong from just going too fast than to not know the answer.

I'm not gonna lose sleep over it but I won't get those questions wrong when they show up on the final. I also will try to keep myself from getting excited and screwing up again.


We started 2-Stroke engines last night a little after the test. I don't like 2-stroke motors. They seem like the biggest waste of gas but if they could figure out a way to prevent them from shooting so much fuel mix out of the exhaust they seem like they'd be quite the powerhouses. I could be wrong on that thought but I'm not sure yet. I'll learn more next week on that.
