Testing....?
I hate when someone goes to a dealer and gets this kinda treatment...
Heres what you do to test.
Using a mirror and flashlight, look at your fuel baffle, along the ring just under the nipples. You should see one of 4 words, om=n, res, vent, ret.
Get a short piece of 1/4" fuel line, about 5 feet in length. Connect it to either the on or res nipple. If you are unsure, when you connect it, blow through your line. You should hear it make bubbles. If it does not, then you are hooked to either the return or vent.
Once you have a line connected to a nipple that makes the bubbing sound, look at your carb. The line in the middle of that plate is your pulse line. There should be a small piece of hose connecting it from the carb to the engine block. That leaves two nipples on your carb, the inlet and return. If you use your mirror, you will see a direction arrow on that plate on where to hook it up. Your fuel line from the gas tank needs to connect to that bottom nipple of the carb, that's in. Now, the only line left is your return. It will come off the upper nipple and be returned to the fuel tank.
That's it, your ready to give it a try. You can not leave this permanent because you are by-passing your fuel filter. Not a big concern for temp trouble shooting though because you have another filter inside the carb.
All of these parts to your fuel system are marked. So, look closely with a bright flashlight and mirror and you will see them.........let me know how you come out.............................:cheers:
