Rebuild carburettor 1989 GQ / Y60

BTW, if the petrol pump plunger is a leather one, make sure to apply bit of petrol or sewing machine oil and lather it a bit to soften the material. Fresh out of the kit the leather plunger is too stiff.

Accelerator pump plunger was made of leather in the repair kit I bought from Burson. The original one was rubber, but it appears the leather plunger is working ok. They may get too dry in an LPG running carby, so it's important to run on petrol for few minutes a day or so to get it soaked with petrol. This is true for the whole carby, not the just the accelerator plunger.

Sorry, I needed to correct the above highlighted. The accelerator plunger my RB30 Nikki carby had in it before I put a kit through(including the new leather plunger) was also leather, not rubber. I got it mixed up with another carby. I dunno for sure whether the original plunger was rubber or not, but the one I had in mine before the rebuild was still leather.

I'm guessing leather is a more durable material 'cos it doesn't react with petrol, comparing to any form of durable rubber made for submerging(and moving) in petrol?!
