You have the timing close but you are running too much fuel. Reduce the pressure to the fuel solenoid slightly and take another plug reading with a fresh set of plugs.

When tuning the motor by reading the plugs you should start by getting the plugs clean. To do this you must lower the fuel pressure to the fuel solenoid a little at a time until the plugs porcelain cleans up. Once you have it running clean then you can start tuning the ignition timing.

A9. In most cases, no. The additional electrodes disturb the flow of gases around the spark plug tip and performance may even be reduced. In addition, for high performance applications the additional metal within the combustion chamber will retain more heat and may be more prone to detonation/pre ignition.

If the soil is really hard or clay, first you must condition the soil with a soil conditioner or add Gypsym to the soil. Then, space the plugs about 8-12 inches apart and stagger the next row. Water them in well and keep well watered the first year until they are established.

Mark the area to be plugged with your desired spacing. Stagger the rows as in figure 1. At each plug location drill a hole about 1 1/4 inch deep. If you are planting a small amount of plugs, a 1-1/4 inch drill bit can be purchased at a hardware store. If you are planting a large number of plugs you might want to consider purchasing the 18 inch Soil Auger in our "Store".

A9. In most cases, no. The additional electrodes disturb the flow of gases around the spark plug tip and if anything performance is reduced.

It's not recommended. Thermal fusion of the pipe, drilling and trenching are procedures best handled by licensed professionals. Nonprofessional installations may result in less than optimum performance, which could cancel out anticipated savings

a fluid is circulated through the buried pipe, it attracts heat from the surrounding ground; the further the fluid flows, the more heat it can extract. When the warm fluid returns to the compressor, heat is taken from the fluid and transferred to the heat pump, where it warms air prior to circulation throughout the building.

It is not recommended. In addition to thermal fusion of the pipe, drilling and trenching are procedures best handled by licensed professionals. Nonprofessional installations may result in less than optimum performance, which could cancel out anticipated savings. Also, warranties are usually void if the system is installed by a non-authorized dealer.

Skin can become irritated after using a pediculicide. This can result in the formation of desquamated epithelial cell plugs (DEC) which people often mistake for nits. This causes many caregivers to overtreat with chemicals thus continuing the cycle. If you are not sure if you are seeing nits, take a suspected nit on a hair shaft to your doctor and have him confirm the diagnosis by looking at the suspected nit under a microscope.

There are several types of systems that gather the heat from the ground. The most commonly used are open-loop and closed-loop systems.

The majority of solar radiation that strikes the earth is absorbed into the ground, and this heat is transferred into the building during the winter.

Yes, by using a device called a desuperheater. Desuperheaters are standard on some units, and optional on others. Producing high temperature water can be very inefficient with heat pumps by comparison to the standard COP rating. The WRB series heatpumps do not have a desuperheater facility.

We think not. The capital cost is very high and they consume electricity, an expensive source of energy. As far as payback is concerned, consider this: If a ground source heat pump costs $15,000 more than a gas or oil system for a 2,000 sq. ft. home, at 8.5% financing the payback is never. Finance charges would be $1,200 which would exceed the entire gas or oil bill and this is before the costs of the electricity required to run the heat pump.

The strap material is called hook and loop. This material is very similar to the material that rhymes with WELCRO.

Fine ground white clay, molded and fired in an oven for eight hours at 1200 degrees. Finished with a glazed, underglazed, or "bisque" finish. Glazing produces a high gloss; underglaze produces a matte finish. Bisque is a matte finish without glaze. After finishing, the item is "cooked" for six hours at 800 degrees.

If the "extra brightness" box is unchecked, check it. Each monitor is different, and many have differrent distributions of brightness to the naked eye (this is called "gamma").

In most cases Bareboat insurance regulations do not permit you to sail after dark. Exceptions are made in some areas for purposes of making a night crossing in order to make a daylight landfall.
