[AT] Cockshutt report

[Greg Whittaker]

I had an M Farmall act much the same way and it turned out to be the gasket 
between the carb and intake.  It'd run good for a long time and suddenly 
start sputtering.  If you fast on the choke you could catch it and it'd be 
alright.  If not it stalled.  I found the problem when starting it.  It had 
to be started by touching the starter cable to the hot post on the battery 
because the button didn't work and since it had a mag and the generator 
didn't work anyway.....  I know starting them from the ground isn't safe 
especially standing in front of a rear tire but I ALWAYS made sure it was 
out gear.  Anyway when I was starting it and had it choked I noticed bubbles 
coming from the seam between the carb and intake.  I put in a new gasket and 
it never acted up again.
