I recently adjusted my vales .06/.08 and also rebuilt my carbs. They were done separate and driven in between. I'm now noticing a pinging sound coming from the carb barrel on cylinder 3. If I put my hand over the carb throat it makes the sound go away. It is doing this at idle of ~950. I will load a video of the sound. What do you all think?

You mentioned the carb on the effected side won't balance as the other setting wise,its not your compression because that is great.
Appears you have a weaker vaccum signal on that side ...must be leaking air ?. I have never liked the thick gaskets supplied with some of the air cleaner kits,they tend to settle in and the manifold can leak @ the head,worth checking? Good luck. |

I have never liked the thick gaskets supplied with some of the air cleaner kits,they tend to settle in and the manifold can leak @ the head,worth checking? Good luck. Maybe I do have an intake leak. When I rebuilt the carbs I put new carb to intake gaskets on, but not new intake to head gaskets. The reason being I never removed the intake manifold. I will first put the plugs back in and check for in intake leak with some starter fluid around the number 3 manifold. Anyone know if the gasket for the head to manifold is included in the Redline weber rebuild kit? |
