Reed Valve Carbon
I did a carb rebuild on the weekend on my 1987 Aspi. They were really dirty.
When I had the reed valves out I noticed that on only cylinder #3 there was an accumulation of specs of carbon around the reed valve. The valves were in excellent condition so I cleaned them and did not change them. The other valves did not have any of this carbon.
I am concerned that this accumulation of carbon is a sign of something going on in this cylinder only. ie. a leaking valve or something. The carbon was accumulated in the corner away from the valve.

Any one have any ideas or seen this before?

Hi Hawk,

When I pulled my carbs out for rebuild it looked like yours, #3 cylinder was much dirtier than the rest.

Thanks for the comment Westwing, I was beginning to think no one cared.
Nice to know that someone saw the same thing, maybe it is norm for this carbon build up to be there. I have been watching the spark plug for that cylinder and it is the same colour as the other plugs. Just thought I would throw it out there to see if anyone had a suggestion. Regards .
