Craftsman Rototiller fuel problem....

This machine sits for 10 months every year. For the past 5 or so I have been able to resurrect it with some starter fluid and a little elbow grease. I all ways run it out of gas before letting rest.
The motor would run if I use starter fluid, or if I poured a little gas in the carb, but it would not pull the gas up from the tank. It would only run a few seconds and stop.
I removed the cover on what I call a "fuel pump" and although the diaphragm was intact, it had no sign of gas reaching it and it was stretched out pretty good, enough to where I though it would not pump.

I'm about to pull the trigger on the diaphragm, spring and the round stainless steel....follower
Model 135202
Type 0145
Code 93040627

My question is this: What other parts should I order to get this thing up and running....short of a new carb.

Had links to 5 pictures and exploded views with part numbers but I guess that is not allowed any more. Kinda s()cks
 
I don't see a need to replace the spring and spring cap. I would just replace the diaphragm, plus the intake and tank gaskets, just to make sure you eliminate any air leaks.

Make sure the fuel line is clear. Blow through it from fuel pump side to fuel tank.

this engine has the extended tube down into the tank, that gets pumped up into the small well on top of the tank were it is drawn up the small tube into the carb venturi.

Guess I should have looked it up before I typed.:laughing:

Their is usually a screen at the bottom of the extended tube of the carb. I have seen them clog up, more so if tank is rusty. If your going to pull the carb I would go ahead and clean the carb.
 
UPDATE 3-5-16

First of all....THANKS to everyone that contributed to this repair. I really appreciate you suggestions and directions.

This afternoon I was able to disassemble the tank and carburetor on this tiller. Seems to me based on your replies I need the tank/carb gasket in addition to the diaphragm pump parts. I have not purchased anything yet. Based on your responses I decided to wait until I had time to get it apart. Hope i can remember how all those linkages re-connect. :ashamed:
I'm considering a new pick up tube but it looks like it may be more trouble than it's worth. Other than some discoloration it appears to be fine...

This rust has me a little concerned, looks like a plug that is rusted, some port that was not used in this application.

I hope i do not get in trouble for this but....
Make sure to always use a fuel stabilizer in the gas. I work for B3C fuel solutions and we make Ethanol Shield which stabilizes the gas and fights the ethanol issues. it will revitalize plastic and rubber parts as well. please google it.
we also make Mechanic in a Bottle that will clean the fuel system without the need to remove the parts.
if anyone wants a free sample, send me an email and i will send you a sample.
