IDA Jetting Recommendation

[Nicholas Taylor]

hi there

i'm in south africa and would like some help with a start point for my cobra with the chevy 350.

It has four Weber 40 DCOE"s. there is a flat spot between 1500 and 2000 rpm.
There coughs and splutters during cruising.

i don't know there cam's as the previous owner whom built the engine pasted away.
i'm at 1000m above sea level roughly.

Any advice?

How are the carbs set up now? There is some great info online. The Inglese Weber Primer is a good read as well as some books that are on the Shelf that will take you through theory & parts of the Carbs.

Make sure you have your throttle plates as closed at idle as possible without having the engine turn off.

Only concentrate on your idle circuit and make sure the carbs are synced.
