So even though they told me on Wednesday that they would have an assembly today to check the my harmonic balance and flywheel with, they didn't. So I had to leave them with them and they said they should be able to do it on Monday. They are going to ship them back to me after so I don't have to drive out there again. This sucks because now I have to wait another week before I know if I have to pull the engine out or if the hamarnic balancer and the flywheel were off. I could have either put it back together this weekend or pulled the engine and disassembled it. Now it'll be next weekend. Well at least I hope it will.

I heard back from CHP today and thankfully it was the flywheel that was off. They corrected it and are shipping it and the harmonic balancer back to me today.

Nice. That would have sucked had you needed to pull the motor back out.

Yeah, I wasn't looking forward to it if I had to. I really glad that I don't.

I got the flywheel and harmonic balancer back yesterday. Hopefully it won't rain tomorrow so I can put it all back together.

I know that's a load off your mind. Nothing worse than putting a lot of work into something and not have it work correctly.

I got the trans installed and the vibration is gone but the car still wasn't running right. I had a new set of plugs so I installed those. While removing the old ones I found that cylinder 4 had a bad plug. It ran better with the new plugs but still wasn't right. So I bumped the fuel pressure up and that helped a lot. It still isn't perfect but I think it just needs to be tuned.

Let me know when you're thinking about going, the blue car is insured now and ready to be driven on the street. We can go down there together and get em done at the same time.

So we had Brendan (Ron's Friend on here) and his wife over for dinner tonight and I took him for a ride in the Cobra to see what he thought. He's an ASE certified tech like Phil is. His opinion is that it's a balance issue. I'm going to have Phil drive it again and if Phil feels that it's a balance issue as well then I'm going to pull the engine and tear it back down to have it all balanced again.

Phil drove the car on Thursday and still thought that it's a balance issue so I called CHP Friday morning and told them that I was going to bring the car down to get their opinion. I picked Guy up and we headed down there. Eric felt it and listened to it and said that it's not a balance issue. Well at first he didn't even notice it. I had him sit in the car because that's the only way you feel it. He said that if it was a balance issue it would get worse around the 2800-3000 range. I asked him what he thinks it is and he said he thinks it's a tuning issue but I don't agree. I've not been driving the car because I was worried about the vibration doing damage but he said that even if it was a balance issue that it is so light that it wouldn't cause any engine damage and Phil agreed. So I'm going to wait until I have it tuned and see. Guy is going to talk to Steve next week when he is back at the shop to schedule and appointment and I'm going to try and see if I can come up with the cash to have mine tuned then as well.
