I am assuming the numbers in the pitcure match the numbers below:
<http://www.gmcmhphotos.com/photos/showphoto.php?photo=43877>
>> 1. New fuel pump.
-- Has it ever ran with this pump? As it is square I assume it is NOT an Onan pump. Is there a filter on the suction side of the pump? These little square pumps are easy to install backwards and do not work that way.
>> 2. End of fuel line. Has the start of some splitting but
>> it looks like it is holding a seal - I'll replace it anyway.
-- Looks dry... as in no fuel. This area should be under pressure when operating correctly. Make sure it seals "really good."
>> 3. Connection into the filter. Holding my finger over this, there is no suction at all when cranking.
-- This is the connection into the carburetor... output of the pump.
>> 4. Choke? What position is full choke, should I be dinking
>> with this when trying to start?
-- The engine is cold and you are trying to start. it should go fully closed when cranking and half closed when not cranking. remember that this engine starts with full-open throttle.
>> 5. Throttle. When I push this, the motor cranks faster but
>> still doesn't catch.
-- As when you push on "this" you are closing the throttle, I do not understand why it would crank faster...
What I would do:
I know many do not like using starting fluid, but I use it to divide, the problem in half. I disconnect the breather hose (between 2 and 3 in your picture) and spray a SMALL amount into the intake side of the carb. Then crank. If the motor fires I know that the "electrical" side is working and move on to the "fuel" side of the problem.
Let us know what you find. (With the dry hose, I suspect you have a problem on the fuel side. look into a small fuel can... something like a outboard motor boat tank would be best.)
