Hi,

I lately did some changes to my cranking / priming tables. Now I do get a backfiring when I start the car in cold wheather (after standing for a day or so - engine cold, outside temp ~12-15°C) - car starts good after that and also when it's warmed up.

What to look for? Priming tables, cranking tables? Too rich or too lean?

Thanks for your suggestions.

Oh and it's a MS2Extra btw. (but I don't think really that matters...)

Greets and thanks

Thanks - priming or cranking?

If the backfire is in the intake, it's too lean...

I would also say lean if coming from the intake.

It's in the exhaust.

just lower the cranking pw at that temp.
