Some Sound recording taken from on top of the carby over the years.

I experimented with the cam position as well.

I have no troubles opening the Vac Secondary.

All are MP3 format 128 kbs download and share files.

Back in 2005 after rebuilding a head and manifold with the cam slightly advanced and a standard distributor I set the timing at various points and recorded the sound wave the even though the next-door complained about my engine noise I could not care less about it.
