I will let you off Ted, us old gits forget the odd thing, where am i posting?
Mike_Berkshire:
Great tip on the cam chain tensioner; thanks Ted/Bryan. I haven’t seen anything that suggests I don’t need to take all the carbs etc off to check where the fuel leak is coming from though - wishful thinking! However, refitting the harness and getting to the cam chain adjuster will be easier without carbs and airbox in the way. Every cloud …………

Holding the kickstart by hand so you are pushing against the compression, having released the tensioner lock nut. Having released the lock nut the chain tensioner will take up the slack, then just nip the lock nut in position. You can then tighten it up properly by using the screwdriver slot to hold the screw and a spanner to tighten it up.
Pretty sure that's how I did mine iirc.

Can this method also be used for the 400/4 Bryan?
Bryanj:
Works on all the Hondas as long as the mechanism is free but with 400 do it first or you singe your hands
Mike_Berkshire:
So I now have the carbs off and have taken the opportunity to properly fit the harness and recheck the cam chain tensioner. That done I put the carbs in a baking tin on the bench and connected to a fuel source. After a few seconds fuel started leaking. The leak; more of a jet actually, came not from the brass tube in the bottom of the float bowl but from the spigot where the carb body joins the float bowl and it looks like the spigot acts for both carb #1 and #2
I have both bowls, floats, hinge pins and float valves off to clean/ inspect and check float heights for #1 and #2 and will rebuild and check again in the baking tin.
Is there any significance in where the leak is coming from?
