Hobes is the handle and Gday to all.
I joined this forum nearly 2 years ago so that I could do the search fro all info regarding my ol girl, a Z750 E1 late 81 model. She has gone a bit os transform, I like bobbers, so she got customed.
I have a full piccie history to show ya, but at this stage I will post that later.
I am in the need of some serious help from you lot.
I have stripped down the carbies, cleaned all holes with carby cleaner and compressed air. I have used new gaskets and needle/seat valve, which I find funny, cos the ones shown out there use one with a rubber tip, this as is the old one is a steel tip. Anyways, I checked and set float heights to what seems the general concensus of 18mm ish? off the gasket set area, as per all the vids and tutorials, re assembled the carbs, set up a dummy fuel tank to see if all was well. The air hole to needle jet tube continually leaks fuel. I have been at it for 2 days now, trying every trick I have seen on the net, but no matter what I do, it still leaks mass amounts of fuel. When ever I turn of the fuel flow, it hisses and then squirts fuel out.
I had another set of eyes run over it but all is where it should be.
questions.
is 18mm ish the right height for these carbs to suit the GPZ?
should the needle and seat, stop fuel flow as the bowl reaches its height, thus stopping fuel running up the needle jet tube and out to air?
as I have blown compressed air thru all holes to clear them, have I accidently blown something out of that one hole? .
do I just give up and send them out to a carby mechanic? all the work I have done mostly myself, except welding the hardtail, so I am reluctant at getting someone else to help me, if it is an easy fix.
I am stuck here, I cant get the newly recondition motor to run with this fuel issue.
any help or question, please fire away, I will try to answer as best I can.
