I want to refurbish an old Keihin PWK 38 but they do not have removeable atomisers. They have a metering block in which the pilot & main jets are fastened, but the atomiser, or needle jet, is integral, unlike the smaller sizes.
I reckon I can adapt an atomiser from either a smaller PWK or even something from another manufacturer. The smaller PWK will need an extension making & then press fitted in.
The issue will be getting the sized hole aligned & I'd sooner not use a drill then needle file, so can anybody recommend a set of jet reamers?
The size I'm aiming for is 2.9 mm, but that's not certain.
Thank you in anticipation
