After having been out of town all last week and playing catch up on everything else in life I finally got back to playing with the car. Last night I installed new headlights, a set of Delta Classics with Xenon bulbs
from Summit. They fit right in with no modifications needed.
Tonight I played with the engine. While I was away I had ordered a colortune kit to better understand what was going on. What I found was number one piston was firing intermittently and number two piston hardly at all
. I am actually surprised the engine ran at all.
I disassembled the top of the carbs to check the float levels and they are fine.
I checked the balance between the carbs, they were a little off at first but good now.
I did a compression test, there all the same, though they seem low. My gauge is 6 or 7 years old and there's not telling how precise it still is. I was happy to see they measured the same.
I found that when closing the choke lever on the front carb I was able to get number 2 to fire. Doing so raised the rpms of the motor also.
Does that imply that my fuel air mixture is way off preventing the engine from firing? As I reduce the available air and bring the mixture more inline the piston fires?
Also how much damage am I doing by running the engine like this. I am not driving it I am merely running in short burst to diagnose the problem.
Thanks for the help.
