Today I drained and replaced the fuel, blew out the pilot circuit again, tickled both carbs and it still would not start
Cleaning the carburetor idle circuit can take a number of tries .
With carburetor cleaner and compressed air often being among the less effective methods .
buy or make an " AMAL
pilot cleaning tool "
with a #78 drill bit .
Most retailers have a version of this
Or you can make your own with the drill bit glued into a piece of WD-40 straw .
( the plastic straw add a bit of flexibility , which is a useful touch )
the drill bit on a stick is Twisted , as it is allowed to push Inward and find its way .
the drill flutes pick up gummy swarf that otherwise might just gets pushed back further inside the idle circuit , with other methods
Make sure the bit is well crimped/glued
Because if you pull the straw out
without the drill-bit it's a guarantee that the pilot jet is clogged
