what does the diaphragm do? how do I know if mine is bad?
1333837
This type of carburetor does not have a float and inlet valve assembly, but draws fuel straight out of the fuel tank using engine vacuum. After awhile the diaphragm looses it flexibilty and so affects its performance (see other answers). The diaphragms used to last longer before our government mandated ethynol in our fuel. I have found using a fuel stablizer increases the life of the diaphragms. Before I regularly treated our fuel, I was replacing the diaphragms for my sons' lawnmowers almost once a year.

It controls the fuel flow. If it's not working properly, the mower will run slowly, surge or won't start at all.

The diaphragm regulates the amount of fuel inside the carburetor. A good one is flexible, a bad one will be stiff and/or damaged. If the diaphragm is stiff or damaged the engine will not run well, or at all. In this case, the diaphragm sits under the gasket. Replacement is relatively easy to do yourself.

It uses manifold pressure to draw gasoline from the tank to be used by the engine. A bad or damaged one usually results in hard starting or no start and if it does start, just won't run very well. An easy DIY and a good time to clean the inside if the fuel tank.

Does it do anything at all? Did you slide down the safety? Do you hear the click or hear gas coming out when you hold the button down? Are you positive you filled it properly?If its full and the button depresses (safety disengaged) but no gas comes out when you hold the button, you probably have a gas flow problem.If the button depresses and you don't hear the click of the spark... you probably have an issue with the ignition.Just be sure you're using it right before you decide its actually a bad unit.If its full and sparks properly... maybe also check the flow adjustment on the side to make sure its turned up enough.

Ours only does that when there is not enough air in the tube. I add air and the problem goes away.

The only way to do a functional test is to add water into the pit until the pump turns on. If the water level is at a point where the pump should have turned on then unplug diaghragm cord from sump pump power cord and plug pump cord directly into outlet. If pump turns on then diaphragm is bad and should be replaced, if pump does not turn on then pump is bad. Majority of time you will find that diaghragm is bad.

"Err P" - Fail to inflate. solution: check if the cuff is properly connected. Replace the air tube if it is broken."Err 1" - Deflate too rapidly. solution: Return for servicing."Err 2" - Movement during measurement. solution: do not move during measurement. Signal interference. solution: remove interfering source e.g. mobile phones, magnets."Err 3" - Incorrect results. solution: measure again.

Sounds like a faulty reed- maybe sticking in closed position. Been playing Sp20's for 20 years- no problems in lower holes until the harp is basically shot anyway. Consult a decent do-it-yourself repair video if you're into that. At 40 bucks for these harps, might be worth your while.

Return it. You have a cracked diaphragm. This seems to be a common problem with the Crossman air pistols and why I do not recommend them. For about ten dollars more you can upgrade to the Colt Defender air pistol which is a far more superior air pistol.

I think it would be....I've used it on infants so I would think it will be fine. Just be aware that the frequencies you want to hear are dependent on the amount of pressure you use when placing diaphragm on patient (human or animal)

Should be clear. After a period of time I think it goes bad. Mine did that very quickly and I tossed it.

Check the O-ring. Also watch for cracks in the "U" tube along the seam as it will suck air and cause the GPH to go way down. Mine started to suck air along the seam shortly after getting it. I contacted AquaClear and they wanted me to purchase a new one even though it was less than 3 months old and still under warranty. Terrible customer support. I avoid AquaClear (and all Hagen) products like the plague now. Both my 30 and 70 models have the same issue and now sit in the very box they came in.... sadly I purchased nearly $200 in filter supplies/media for these as well. I just cut the stuff open and use it in my new filters. Return it if you can. Check the O-ring.

There is a pressure relief that might be leaking or you may not have the lid-pump assembly screwed down tight enough. I always put a little water on the O ring so it will help it seal. Also you might put a little water down the top of the pump and it might help the diaphram seal it's self. It will just pump hte water out of the pump housing.

would like to know if this diaphragm is fine for baracuda super genius. because the attack seems different

It takes only a few moments to inflate, check the connection to the pump, make sure it's secure and the right side up, also check all the lines so there is no air leaking from them. If all else fails, you can contact the vendor, they've been very responsive to questions.

make sure the pads are connected properly. When you increase the the amount of the current it will "tighten" you muscle and actually draws your bottom up, I only use it when I'm laying down watching T.V. I found that I've had to change the pads more often then was implied on the comment section, but I do move the pads over a little prior to finally switching them for new ones. What I mean is where the indentation is on the pad, I move it over enough that there is a fresh part of the pad to have connection. if you still feel like you are feeling "zapped" or like there are needle poking you, get new pads. make sure the pads are connected properly.

You should return it right away with an explanation and ask for a replacement. I have had mine for a few months and no problems so maybe just a bad part.

Not if your only spraying the outside. If you spray inside you may inadvertently get spray on the diaphragm and ruin it.
