First post on here guys and it's a request for info on the size of the pilot jet internal bore on a 1978 F2 Phil Read Replica.
Trying to get the old girl going again after years of none use. During carb cleaning I have pulled the pressed in pilot jets out to check for restrictions. Looking at either end of the jet the bore seems to be of similar size, and I can get a pin into the jet from either end but not all the way through. At the point where the jet tapers down externally the pin will go no further. Am I correct in thinking that the internal bore reduces substantially towards the middle of the jet. The only wire I can get through fully is a strand on copper wire that is almost hair like in diameter.
