How do I repair a constant water drip into the washer tub? Thank you!


The water inlet valve has something caught between the diaphram & body or the diaphram is split. If it is the type with screws in it you can pull it to pieces, remove the foreign matter or replace the diaphram if damaged (if you can buy one). Alternately replace the valve.

Chainsaw will not crank


this is classic fuel starvation, start, if you have not already done by replacing the fuel filter in the tank, if no better replace the fuel hose in the tank up to the carb, if no better remove the carb, under the pump side carb cover ( normally alluminium ) here you will find the an internal filter, clean or replace, if the pump diaphram curls up then replace, remove the metering side cover of the carb, check the metring lever here moves freely and lifts the needle, when re assembling on the metering side the gasket is used as a spacer so must go on first then the diaphram and cover, on the pump side the diaphram must go against the carb body followed by the gasket and cover, re set the jet screws to one and a quarter turns out from closed, if the saw is still not starting it is most likley a massive air leak, check the manifold between the cylinder and the carb for cracks, splits or loose, replace the crank seals, replace the cylinder base gasket

Cannot start my mcculloch mac160s. geting spark. i heard that a diaphram in carb could be suspect. is this common? what else should i look for?


Start with the easy things first, pull the fuel hose from the tank and replace the filter on the end, check the fuel hose up to the carb for cracks or splits, the carb has two diaphrams, a metering diaphram, which controls the amount of fuel in the carb, much like a float bowl on a normal carb, and a pump diaphram, which pulls fuel from the fuel tank, into the carb, these two items have a long service life, if they have aged or the material attacked by the fuel they can become stiff and not work very well, however i think it unlikley that the saw would not actually start, it may run bad, but it should start.

Model 141 husqvarna saw would cut off as soon as i hit the throdle now it will not start


For some reason its running too lean on the mixture, this may be due to a fuel blockage, or it just wants richening up on the mixture screws, start by replacing the fuel filter in the tank, check the fuel hose up to the carb for signs of leaking/cracks or splits, if the carb has standard screws to adjust the mixture, turn each one ( H and L ) out 1/2 turn ( anti clockwise ) on each, if it still does not run any better it may need a carb service. To remove the carb, first remove the two screws securung the air filter, then remove the two 10mm nuts securing the air filter back plate, remove the wire throttle rod, now remove the two cross head screws from the carb back plate into the crankcase, finaly remove the the two 7mm studs securing the carb, remove the fuel hose from the carb elbow ( use a suitable plug to stop fuel sqirting out of the hose a set of forseps works well ) with the carb off remove the single cross head screw in the alloy pump cover, here you will find a gasket and a pump diaphram in that order, there will also be a main fuel screen which will need cleaning or replacment, if the pump diaphram looks aged replace this importent component, now turn the carb over and remove the four screws securing the metering cover, here you will find the metering diaphram and a gasket in that order, replace the diaphram if it looks aged or the metal disc is bent, the metering lever controling the inlet needle should move easily and be set level with the sides of the carb body, if too low just bend it up, if too high bend it down, this is about as much as you can do with the carb without special tools. Whilst the carb is of check the induction rubber, to do this remove the two m4 allen screws holding the carb back plate on, pull the back plate up and out,behind here you will find the induction tube, make sure it has not split, below this tube is the impulse seal check this is seated correctly and not split.
Let us know how you are getting on.

When we flush, rather than the tank refilling in a continuous intake, it now takes in water in a series of "sucks." It started with just 2, then 3, now it's many. What do we need to do or to replace?


sounds like your tolite has a pressure fill switch. This would be a low profile water intake in the bottom of the toilet. You can go to any plumbing store or Big box hardware store and buy a replacement. Personally I would go with a fluidmaster. easy to repair. If you have a fluidmaster Gray stem with black top and float - buy a diaphram for about 99 cents and replace. turn off water at shut off valve behind toilet - twist off top of fluid master 1/4 turn counterclockwise - turn over remove old diaphram black rubber thingy in middle and replace with new diaphram twist on 1/4 turn clockwise.

One valve of my Vigoro timer will not close completely. It's been in use since about March. Could it have sand lodged in the valve? Can I fix it myself?


I had the same problem with several of mine. So I tore one apart. The problem isn't that the valve doesn't close. The valve uses a rubber diaphram that flexes in and out, sealing off the water supply. The rubber diaphrams develop cracks, allowing water to pass through the valve. The rate of water flow depends on how large the crack is. The crack will become larger over time as the valve moves the rubber diaphram in and out. The diaphram can be easily replaced. However, these units are not designed to be taken apart and repaired and I can't find a replacement for the diaphram. The bottom line is that once the diaphrams crack (and my experience is that they all do within 1-2 years-time), you have to throw it away and buy a new timer.

My 1991 toyota truck idles fine whe io pre ss the gas it will go up then down fine when i hit the brake it starts to race up then down when i let off the brake it quits?


rule out the brake booster diaphram, remove the vacum line to the booster and plug the hose up, handbrake on, start the engine, if it is ok then you have a split diaphram in the booster, see your local brake shop for a replacement.

the diaphram is the pushing force for the gas valve to open, if you have a split or worn diaphram it will ned to be replaced.
