Re: 1928 Hudson Starting Problem [1 Attachment]

Jim, a beautiful car!!  As Geoff says
replacing the  tube in the heat riser is not a big deal.  I f memory
serves, I used 1-5/8 od exhaust pipe, after worrying the old tube out I found it
helped to machine about .010 off the diameter for about 1/2" from the bottom of
the new pipe.  this helped with pressing in the new pipe and measurements
indicated it was required.   However this was on a 1929 and 28s
may be different.

Thanks very much, Geoff.  As soon as
I get my house deck rebuilt I will delve into the problem -- glad to hear that
the inner tube isn't part of the casting.  As for the butterflies I have
redundant ones -- both the original and the one from the Zenith are hooked
together.  Seems a bit much since this isn't part of a nuclear power
plant!  The original will go by the wayside soon. 

 

I've attached a photo -- 50,000 original
miles on the car; came from Hawaii.

 

Thanks again,  Jim Gilbert

JIm, put your hand over the inlet of the carby,
with the throttle wide open, and get someone to push the starter
pedal.  There should be a real strong suction felt. If not, you have
hit on the problem, a leak in the heat riser.  A simple enough job to
replace the inner tube with either copper, stainless, or original type plain
steel.  It's taken 81 years to rot out, so a plain one will probably
see you out!  also check what has been done  with the original
throttle butterfly, has it been discarded, or wedged open or
what?    Preferable it should be taken out, and the ends of
the holes blocked up to eliminate air leaks. 

Geoff.

Problem

Hi, everyone.  I recently
purchased a very nice 1928 Hudson Landau Sedan.  The car is very hard
to start when cold and worse when it warms up (the original Marvel carb
has been replaced with an updraft Zenith of unknown pedigree).  It
also tries to stall at stop lights unless you grab the choke. 
Although I haven't shaken it down, I suspect a vacuum leak in the heat
riser setup.  Any suggestions (and if there's a leak inside the heat
riser is there any salvation)?  The engine pulls fairly strongly and
smoothly once you get rolling.

 

Thanks very much,  Jim
