26 mill carbs

Does anyone know what happened to the standard px carb which (i think) sip then bored out to 26 mill? were they actually any good cos it sounds kike a good compromise between standard and say 28mill which, going on the posts on this board, cause trouble?

Everyone I know who has brought one has had problems.

the sip 26mm carb is a good one especially for „cruise“ tuning such as a rally going 210 that you dont want to scream about on but just require a torquey tourer thar will cruise all day.it also means that you can keep the auto-lube.by messing about with jetting etc you will find good performance without big fuel bills.also works well with 166/172/180cc conversions.i have had many good results tuning and setting up px’s with this carb
