Unit won't prime, - Wagner SprayTech Wagner Airless Paint Spray Unit Project 115

pull the carby off and have it rebuilt or re-kitted
the carby is not pulling fuel through for it to run but the primer , which is a small pump, is

the priming bubble can look totally perfect, but all it takes is a pin hole and right around the retaining ring is hard to spot a crack and you should also check fuel lines in tank

The main jet of your carb is clogged and you need to open carb and clear the obstruction - spray carb cleaner on the bolt that holds the gas container to bottom of carb - also spray all the innards along with any tube that protrudes into the gas can.

Then using air compressor blow the sucker out and reassemble. That should do it.

sounds like your fuel pump weak, need to check fuel pressure when engine won;t start and check with engine running

your fuel system needs to be primed

I had the same problem, the machine is two monthsold, and found a way to fix it. This is my second unit as the first unit failed after 14 months. Removing the resovoir and using my finger to push up on the valve that allows the resevoir to drain into the base unit always worked for me for perhaps a day. I got tired of doing this and three days ago I glued an 18 ga copper circle the end of the valve to open the valve wider when the resovoir is seated in the base unit. While it has only been 3 days so far there has not been a prime problem. I also us K-cups and the unit leaked water every time. I removed the rubber grommet on the lid and place a folded piece of aluminum foil (8 layers) that i pierced to fit over the needle that punctures cup. I then pkaced the grommet back on the needle and have had no leakage since. Hope this helps you.

The pressure regulator is bad,it is allowing the fuel to pass threw to the cylinders,replace the regulator,and a new set of goos spark plugs.This is the fuel pressure regulator.
