I did a compression test and here are the results. (Cylinder #- PSI Reading) 1-160#, 2-175#, 3-160#, 4-180#, 5-165#, 6-161#, 7-164#, 8-150#. It seems to me cylinder 8 has something going on?
At 150psi you will not notice any difference in running. Keep looking.I did a compression test and here are the results. (Cylinder #- PSI Reading) 1-160#, 2-175#, 3-160#, 4-180#, 5-165#, 6-161#, 7-164#, 8-150#. It seems to me cylinder 8 has something going on?
Yes. That is new. Didn't do that before all this started. The carb sat on the shelf for about 3.5 months.Is that "sneezing" through the carb I'm hearing during light revs?
You could do a leak down test. You also could get a bore scope and look at that suspect cylinder. Like I said at one time I will bet you accidentally got something in that motor when the intake was off. Noise, miss, and pulling wires did not change the noise. This tells me there a very good possibility of a nut or washer in the hole. You had better find it now before it really does some damage.

The hole you're talking about,I'm assuming, is the intake port on the head? I had stuffed paper towels in each intake and exhaust port for that very purpose. To keep crap out. Seems like I'm going to have to pull it back out and tear it down again. Yay me...You could do a leak down test. You also could get a bore scope and look at that suspect cylinder.

Yes hole meaning suspect cylinder. You can buy a bore scope fairly cheap and you could look in each cylinder and see what the piston tops and valves look like. You might see something and then you can at least pin it down to a particular cylinder.The hole you're talking about,I'm assuming, is the intake port on the head?
