Howdy Danno ! good to see you here again it's been a while !
yes like a dummy I didn't really take pictures before disassembly ,,,and I will not make that mistake again ! (lesson learned)
....
What I am refuring to is the cross over pipe at the back of the carbs just under the yellow fuel line in the picture above... there is a connector between the carbs and I think that was sucking air that changed the idle when I spreyed the carbs.
.... Gordon if that is just a vent tube to the carb bowls it wouldn't change the idle would it ? it has to be a balance tube to effect the idle !
....
Danno has given me alot to read up on again so I will get that done and then get back here.....
thanks Danno I really appreciate your help !
Bob........
