[AJD] 1930 GP Leaky Radiator, Ensign Carb, Air Cleaner

[Terry]

Luke,

Don't really have anything specific about your GP, but the carb on my '50 A
gets really cold too unless I'm really working it.  I've had it frost up on
a 90* day until the engine gets thorougly warmed up.  I thought that was an
early JD design that allowed you to refrigerate a "cool one" for after you
were done working the field :)

Hi Don,
 
Yes, this carb has the water injection. The tube is pinched off on the carb
and the block is also blocked off so it is not functional. The carb isn't
icing up but feels really cold to the touch. It has tremendous compression
so I don't think the intake valve is bad. Plus the problem comes and goes,
and if the intake was bad I would think it would consistantly need to be
choked.  I'm going to stop after work today at NAPA and get some of the
Berrymans Gas Additive. I'll try that first and maybe it will dissolve some
of the gunk if there is any in there.
 
Also will pick up the Barr's radiator stuff.  Anybody know how many gallons
the radiator and block holds? I'm not sure how big of a container to get. I
didn't check the bolts holding on the bottom of the radiator. It's actually
leaking where the tubes or fins enter into the bottom casting I think.
 
I'm not sure what the air cleaner material was made of. What kind of solvent
should I soak it in? Mineral Spirits?

did you check the bolts holding the botton tank on? You might try some
berrymans gas additive in the fuel , cleans out the gunck in the fuel line
and carbon in the uppper clylinders. Running with the chock on could be an
indication of a bad intake valve, but if you haven't taken the carb apart
and cleaned it out could be some old fuel restricting the fuel. You might
try turning the idle or power adjusting valves to see if it changes it, they
should be a turn to a turn and half. How cold is the carb? is it iceing up ?
Does this GP have the water injection valve?

Is the stuff in the air cleaner animal or vegtable fiber or is it the spun
metal that a good soaking in solvent would clean out? I think most JD's air
cleaners were soldered or spot welded together.

Don
