Hi everyone,
Some time back, my a/c met with an unfortunate crash.
The result of this crash was some broken cooling fins on the engine, and a some light damage to the muffler.
The High-speed needle (HSN) assembly too suffered some damage, however the engine as such seems to be running fine.
However, one thing that I noticed was that the HSN setting had to be changed completely.
As against the normally recommended setting of approximately 1.5 turns, I needed to open the HSN by only 0.75 turns.
- Opening the HSN beyond this would result in the engine running too rich.
- Also the HSN has become very sensitive.
I suspected that the issue might be in the HSN assembly, so last week I replaced it with a completely new one.
However, the problem still persists.
Can anyone help me with this?
Is it okay to run the engine at 0.7 turns, even though its not acting Lean in any case?
Or could this be some other issue?
- The muffler seems to rotate a bit due to the vibrations and perhaps leaks some (really very little) oil.
But I thought that this would make this engine lean (due to reduced back-pressure) rather than rich.
Thanks in Anticipation,
