It knocks when I start it and gets faster as I accelerate.

Hi,

Do you feel the knock is coming from the engine or a different area on the vehicle? If you feel it may be the engine, take a look through this link:

Next, is it loud enough to record and upload for me to hear? If so, could you do that?

Let me know. Also, let me know if there is anything that changes the sound or volume/pitch. For example, does it stop if you take your foot off the throttle?

Take care and let me know.

Joe
