Plastic Main jets on a 4L1

[shaunthe2nd]

Been stripping and cleaning some carbs today and looked like most the internals had been replaced in recent years with new.

My surprise was that the 190 mains jets are made of plastic.

Never come across this before, usually brass.

My plan is to replace but wondered if anyone come across this before? any good?

yeah, plenty of plastic jets about, pretty old skool now, but was used a lot way back, nowt wrong with them if made accurately
