I bought this motor 2 years ago sat in a guys shop it was nice and shinny. so i bought it. took it home change the plugs got a new fuel cell and hoses and gas. after a couple pulls started right up im thinking great took it out it was hard to start but finally started. next trip i used my minnkota went all around a lake started getting low on charge so i went to fire up the motor no go no start. got home changed the plugs and no go asked a guy and he said fuel problem so i took the carb off cleaned every thing but tore the gasket going between the block and the carb i thought it will be fine. i cleaned all the parts and whiped off the gaskets in the diaphram. cleaed the screen where the fuel enters the diaphram. i sprayed it with starting fluid and got it to go for a couple seconds til the started fluid ran out i guess but thats really it can this be cus the diaphram gasket or something. i took the cap off the fuel cell cus i thought it was a vent i even ran the line directly in the tank. need help please help

Do you have the fuel line flowing in the right direction?  I did that once a long time ago.  I thought I was going to throw the whole motor in the river until I figured it out.

Check the idle needle... is it a two or a four?

If it runs on starting fluid, which in no way should you be using because it has no lubricant and quickly washes of what little is in the engine, leaving the bearings, crank, rings and everything else running dry, metal on metal, giving it a very short life span, it has to be a fuel problem.

Is the fuel pump built into the crab or separate on that one? I would suggest getting a carb kit and if the fuel pump is separate, a fuel pump kit also and build both and do a proper cleaning. If there's an inline filter, replace/clean it.

From now on, mix you up same gas and oil at a 50:1 ratio and use that in a spray bottle to squirt in the carb. DO NOT use starting fluid, if will destroy the motor.
