i should think this is no different to the large bores, more a boost related issue, but what damper spring(s) should i consider using on a 10psi upwards 998 engine?

After a bit of a search it seems a few bods are using yellow springs, but i think that the carb I got off mr flan already has one? is this std or an upgrade?

at what point should you consider going for a stronger spring?

cheers all

I think I hae the Avonbar 'high pressure' spring in mine.

I don't know what others use, but streching the spring a bit can help, although when you think about it it should make little differance.
