Subject:Zenith T4X carburettor for DeLuxe 1927/28 Date:Sun Jul 6 12:50:54 2014
My Henderson is now fully overhauled, and the engine and gearbox is for all practical purposes totally new, rebuilt by Jörgen Sundberg in Sweden (Grevbo Engineering). O still have problems with the carburettor though - hesitation when it comes off the idle (pilot) jet - a hole in the middle. I have tried all sorts of solutions without success - new main jet (size 20) and new compensator jet. The carb has been modified somewhat by an earlier owner, and I suspect that perhaps the idle jet mechanism is not functioning properly, or the choke tube (new) is too large.
I am now looking for a spare carburettor in good condition, or somebody qualified and willing to overhaul mine to original specifications.
Is there help to be found somewhere?
