more 1600 CT timing quetions
Posted: 12 Sep 2025, 04:07
Hello everyone,
I am brand new to this forum and to my 1979 single cab transporter. I imported it to me in Canada from Poland. I am really trying hard to wrap my head around the ignition timing. It has a Bosch DVDA dist. and a solex 34 pict 4 carb. The truck has the 1600cc Aircooled CT engine. I see some posts saying to time at 10 degrees BTDC and some I have read about timing ATDC. I think these different settings are due to the both vacuum lines on or off? If anyone out there is willing to make this as simple as possible for me I would appreciate it. I have a feeling it probably is simple and Im just overcomplicating things. I have included a few photos for reference if that helps. Thanks.
