My procoat won't prime - Wagner Tools & Hardware - Others

you can disconect the switch ,plug it in,pull out the plug and reconnect

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

Hi,

There is air in the lines and it is blocking the water flow...

had the same problem i sprayed wd40 where the suction tube goes and primed three times hope this helps

One cause for this is that one or both of the check balls in the piston are frozen in place. This can be caused by drying paint on the check balls or seats or, as is the case many times in our area, if you did clean the machine well with water without any airless conditioner in it, sometimes the water dries and leave behind minerals that 'lock' the check balls in the seats. Set the machine up in water and turn it on to prime. Using a hammer hit the pump head where the piston is working fairly hard. You are trying not to break anything but knock the check balls loose. If they come loose and water starts cycling through the system, let run a while to wash anything out before switching to paint. If this doesn't work, you may have to take the head apart to see why the check balls won't free up. It could be because of peices of dried paint that won't come loose by themselves.

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.
