Question about Panasonic PT-47WX49 47" Rear Projection Television

1 Answer

Convergence floating My red convergence 'floats' off center by about 1 inch. A slight tap on the side of the set resets it temporarily. This occured about 1 year ago, then worked fine until this weekend. Now it will not stay set. If I attempt to reset the convergence, it doesn't hold. I can't get this to a repair shop. If someone could identify the part required and it's relatively easy to replace, I could do it myself, or at least I could tell a repair person to bring that with them. Thanks for any help, bilacqua@yahoo.com

First thought should be that you have bad solder conections resolder all around the vertical and high voltage and see if that clears up your problem. good luck windman

Flooding xj900


Hi I had the same problem after rebuilding my CB900 carbies a few years back.

The floats hang down so far in the carb that they actually get stuck down even when the fuel flows in after a rebuild.

Turn the fuel on and tap the bowls with the handle of a screw driver (plastic) I used a long shaft screw driver that way you can pretty much get all of them from one side.

This light tapping jults the floats and it allows them to pop up with the pressure of the full bowls if helps with them moving.

Hope this helps.

Might be fuel leaking from overflow. Perhaps the float valve is stuck or damaged, allowing the float bowl to overfill. Slight chance tapping on side of carb may seat the valve. If not, it will probably have to either be set, or replaced. Could possibly have some "gunk" stuck in the valve seat from the cleaning. It only takes a tiny speck of debris to hold the valve open, causing flooding. Another possible cause is that during the cleaning, the tab that adjusts the level of the float valve got bumped, changing the level.

Problem with starting my bike


Sticking floats or worn float valve needles or incorrect float height, tap float bowls to see it overflow stops (sticky float), remove and clean float bowls and fuel inlet passage with carb cleaner and compressed air, check float valve for wear to the rubber tip. Reset float height by slightly bending the metal tab on the float to adjust the closing height of the valve measure from the carb bowl mating surface to the top of the float when fitted then re adjust 1mm at a time higher untill fuel doesnt over flow.

Hi i got a zzr 600 im not geting fuel to carb 2 or 3 and no fuel in float chambers but runs on 1 and 4 for a bit thans terry


Sounds to me that the float may be stuck in the raised position for that carb. This will keep the needle vavle closed preventing fuel entering the float chamber. has the bike been left in the garage for a while on its side stand if so that might also indicate that the float pivot pin is worn and as the fuel evaporates the float has jammed against the side of the float chamber. Carb cleaner slight tapping of the side of the carb float chamber and possible a squirt of compressed air. All worth a try before a massive strip down. Jim ex heli-mech.

Im having one carb that floods over at idle. i but carb kits in and all jets. the floats are set at .62. the carb is on the rt side and the front one.


If the needle and seat are in good working order and this occurs when bike is up straight then you may have to change the float level on that carb. SLIGHTLY
Good Luck

I have a 1984-85 holley 4 barrel and it has


Electric fuel pump most likely has too much pressure for the carb. AFAIK, the Holley 4150/60 & 4165/75 should each demand the usual 4.7-5.3 PSI (4.7 @ idle, 5.3 @ max RPMs), so even the Holley red pump would need some restriction from a regulator. If you want this to be adjusted to its best efficiency, you need to have a fuel pressure gauge installed temporarily, if not on the regulator like I have on my Scout II. FWIW, the regulator I have installed is the Mallory 4307M from CenturyPerformance.com, Summitracing.com, Jegs.com, etc.

http://www.malloryperformance.com/pdf/4307M.pdf

A bad Needle & Seat will do this also, or debris stuck between the Needle and the Seat. This is where light tapping on the bowl helps, but it's best to run the fuel out of the bowl a few times and then the volume flow, or quick filling of the bowl, should loosen up the debris.

You also could have set he fuel float too high. What model carb, the ones I mentioned above (AKA Holley Modular Carbs)? If so, then Holley's site has a tech center & instructions on setting the float(s). www.holley.com

Set the floats carefully and slowly/gradually. Make sure the lock screw is always loose enough before turning the adjustment nut. If you strip out the bowl's threads on an older carb, you'll beat hell finding a replacement. 1/12 turn = 1/32" of fuel height IIRC. You set the fuel level, with pump running (wrap a rag around the carb so gas doesn't leak onto the manifold!!!) so the fuel is just starting to dip out of the "peep-hole" in the side of the float. Removal of the peep/seep-hole screw/plug is necessary first. Clockwise rotation of the nut lowers fuel level IIRC and counter raises fuel level. Again, please check their website. Most people get discouraged when dealing with the Holley Modular Carbs, but they are the simplest and the best carbs on the market. Even if 30+ years old.

How to set the floats on 1980 honda fcivic


YOU CHECK FLOAT LEVEL LOOKING AT THE SIGHT GLASS ON THE RIGHT OF THE CARBURETOR.FUEL LEVEL SHOULD ALIGN WITH THE DOT ON THE SIGHT GLASS.IF THE LEVEL IS ABOVE OR UNDER THE DOT THE CARBURETOR HAS TO BE DISASSEMBLED.TO SET FLOATS REMOVE AND INVERT THE AIR HORN UNTIL THE FLOAT ARM JUST TOUCHES THE NEEDLEVALVE OR THERE IS ABOUT 0.1 mm OR 0.004 INCH CLEARANCE BETWEEN THEM.MEASURE THE DISTANCE BETWEEN THE BOTTOM OF THE AIR HORN GASKET INSTALLED.AND THE CENTER OF THE BOTTOM OF THE FLOAT.THE DISTANCE SHOULD MEASURE 36.4 mm 1.39 - 1.47 INCH. ADJUST BY TURNING THE NEEDLE VALVE SEAT.BE CAREFUL NOT TO ALLOW THE VALVE SEAT TO PROTRUDE FROM THE SEAT ATTACHING BOSS.WHICH WOULD ALLOW THE VALVE TO FALL.IF THIS IS THE CASE BEND THE FLOAT ARM SLIGHTLY UNTIL PROPER CLEARANCE CAN BE OBTAINED.WHEN CARBURETOR IS INSTALLED CHECK FLOAT LEVEL BY LOOKING INTO THE CARBURETOR FLOAT SIGHT GLASS I MENTION IN INFORMATION ABOVE.IF YOU HAVE A 1487cc AND 1600cc CVCC MODELS WITH THE KEIHIN 3 BARREL CARBURETOR.THIS WOULD DEALERSHIP JOB.THIS TYPE IS HARD TO ADJUST.

Carburetor float spec


I am not exactly what you are seeking here, but if you mean the fuel level as controlled by the float it is supposed to by 1/8 of an inch below the float bowl gasket. This is measured by using a special tool consisting of a bowl plug with a plastic tube going through it's center and then holding the tube alongside the carb bowl.You must then adjust the tang on the float to attain that 1/8 inch.I suppose you could fabricate such a tool, but I got mine from EBAY. I have a picture for clarification but I have no idea how to send it to you. moz-screenshot.pngmoz-screenshot-1.png

1986 kaw 454 ltd carbs leaking gas into airbox anybody know how to fix?I had. the carbs rebulit twice. the last time at the dealer lasted about a year.any body help me.


You have float and/or needle and seat problems. Remove the hoses from the air box to each carburetor. Set bike on center stand or block up to get it level--turn on fuel tap and watch for leakage from each carburetor. Turn the fuel tap off. Pop the float bowl off of any that leaked, remove the float and pin--catch the float needle. You probably have debris in the seat area which causes faulty float action. Turn on the fuel tap again and catch the discharge in a clean small jar. Look for rust or other particles in the fuel. If all carburetors are affected, look at the fuel strainer screen just above the fuel tap bowl--no holes and seated properly. You may need to flush the tank if the interior is rusted or full of dirty fuel.
