The first thing that you'll need to do after you have the water off is to cosmetic
spray bottles wholesale make sure that you know what is wrong with the sink sprayer you're going to fix. There are a few things that could be wrong. First, a lot of sink sprayers have reduced water flow because there is something blocking the front of the sprayer.One of the most common problems like this is hard mineral deposits. You should be able to tell if this is the case right away - there will be a hard, white residue all over the sprayer head. This is also very easy to fix. Just take the sprayer head off and clean it. The best way to clean these is just to soak them in a vinegar bath. The slight acid will eat through the deposits.Sometimes you will find a sink sprayer with mineral deposits that just does not get clean in a mineral bath alone. In this situation, don't worry! It just means that you have to do a little bit more work, but you will get it cleaned up in the end.
A toothbrush is a good way to clean off the deposits without harming the actual sprayer head. Don't forget to clean inside of the head as well! There are probably plenty of mineral deposits inside of the sprayer in addition to the ones that are outside of it.If the sprayer is leaking near the sink, then the problem is likely a loose washer there. You can unscrew the sprayer from the sink and check it out. Generally, this can be fixed by tightening the washers and bolts down again. You might want to make sure that there isn't a mineral build up on these parts either - but if there is, you can clean them the same way that you cleaned the sprayer head.Finally, if the sprayer is still not working correctly, you may need to tighten or replace the diverter valve. This is a valve located underneath the faucet itself. The purpose of this valve is to put water through the sprayer while it's in use instead of through the faucet. In order to repair this part, you'll need to rip up the entire faucet.AcceleratorPump Lever AdjustmentDonot forget about the accelerator pump lever adjustment. For oval track use, thepump lever should be adjusted so there is no play in the pump linkage when hethrottle is closed. This will assure that there will be no lean stumble whenthe carburetor comes off idle. Tuning an accelerator pump for maximumperformance off the corner often involves reducing, rather than increasing, thepump volume and discharge rate.
Dragracing calls for a slightly different approach. For the hardest starting linelaunch with a foot brake, the pump lever override spring should be adjusted sothat fuel starts to discharge through the nozzle at an engine speed lower thanlaunch RPM. If a car leaves the starting line at 5000 RPM, the pump shot shouldbegin at 4700-4800; an 1800 RPM launch calls for the accelerator pump shotstarting at 1500. The key is to have no slop in the accelerator pump system atstarting line RPM, so that the pump shot is not "used up" below thatRPM. Although adjusting the accelerator pump as described will create a lot ofslop in the pump linkage at idle, (and may produce a stumble when driving inthe pits) a car will leave harder. Drag cars equipped with a stick shift ortransbrake, where starting line launch is accomplished with the carburetor wideopen, requires adjusting like an oval track application. FloatLevel AdjustmentWhenassembling a carburetor or reinstalling the fuel bowls, you need to adjust thefloat to be approximately 0.450" from the top of the bowl (in line withthe bowl screw bosses when the bowl is upside down). This "dry" settingis to get you in the ball park. Recheck the float level with the engine runningand the sight plugs out. Fuel should just wet the outside of the bowl as thefuel seeps out. On the secondary side, where the sight plug is lower, fuellevel should be slightly higher. On Demon carburetors, the large, patentedsight glass windows allow float level setting without having fuel escape fromthe float bowl. You can adjust the float level relative to the three cast-inmarks next to the float window. PowerValve TuningThepower valveýs function is to supply extra fuel for wide- open throttle, highload conditions. When manifold vacuum falls below the vacuum level stamped onthe power valve, the power valve opens and enriches the main circuit by aboutsix to ten jet sizes.
This occurs under high engine loads such as fullthrottle. The power valve number should be at least 1.5-2.0 in/hg of vacuum under engine idle vacuum. If anengine produces 8.0-9.0 in/hgof vacuum, a 6.5 power valve would be a good first selection. Using a powervalve with a rating lower than this will delay the enrichment and can causehesitation. However, on an oval track car with restricted carburetor rules,using a power valve with a lower rating can sometimes help performance comingoff corners. Any drag race carburetor with a secondary power valve must beturned sideways to avoid fuel starvation. The power valve is higher than thejets and is the first to be uncovered as fuel is pushed to the rear of thefloat bowl. Since there is no way to foundation bottle put an extension on the power valve, thecarburetor must be turned sideways to eliminate fuel starvation.
