Choose an efficient gas chainsaw from one of the most respected chainsaw brands. The Husqvarna 435 has a built-in fuel pump and auto-return stop switch. The starter cord is easy to pull, and the engine is quick to start.
The fuel filter on a Husqvarna chain saw helps feed fuel from the tank into the engine. The fuel filter is connected the fuel line inside the gas tank. The fuel filter blocks dirt, oil and woodchips from getting the fuel line dirty. Using a good fuel filter is essential for running your saw over long periods of time.
Carbureted engines often use low-pressure mechanical pumps that are mounted on the engine.
The fuel filter helps keeps impurities from entering into your carburetor. If your chainsaw begins to stumble or shut off when operating, it might be time to change the fuel filter. Over time, the filter clogs because of sediment and impurities.
Do All Chainsaws Have Air Filters? All petrol-powered chainsaws are fitted with air filters. They may not be the same on all machines, but the ways to clean them are.
To work properly, chainsaw chains and bars must be lubricated with specialized chainsaw bar oil. Husqvarna bar and chain oil is formulated for Husqvarna chainsaws, keeping your saw protected and running as smooth as possible.
Fuel and Air Intake

Filters for carbureted engines may be located at the inlet of the carburetor or inline. Filters for carbureted engines do not need to withstand the same pressures as those for fuel-injected engines.

The easiest way to tell is in the way you cold-start the engine. With a fuel-injected engine, you don`t touch the gas; you just turn the key and it starts, because the injector automatically spritzes fuel into the engine. * Once or twice.
Carbureted engines may require as little as 28 kPa (4 PSI), while modern multipoint fuel injected high-performance engines can require as much as 414 kPa (60 PSI).
All carburetors use some type of accelerator pump circuit. This is necessary to compensate for a very quick opening of the throttle. Carburetors rely on air velocity, through the carburetor to operate the main metering circuit.

Why will my1994 bravada not start?
ANSWER : Very possible your new pump went out again, or was not installed correctly. Check fuel pressure. If you know electrical you can jumper the relay to run the pump. On some GM models I have seen a test wire for the pump underhood.

I have a Echo leaf blower and I can get it running but then it’s cuts off after just a few seconds. It has new plug, air filter and fuel filter. What else could it be?
ANSWER : The carburetor could be dirty and need a good cleaning and you could first remove the fuel pump cover (cover without the vent hole) to the carburetor and look for the small, round, fine-mesh screen. Sometimes it gets covered with dirt and debris and has to be cleaned as it allows the fuel to flow into the metering side of the carburetor.

How to prime a sand filter pump – INTEX Sand Filter Pump
ANSWER : It depends on the pump but most pumps have a filter bowl with a screw on cover – you need to fill this with water and start the pump. if the pipework connected to the pump and the filter are empty you will usually have to repeat this process a few times, but once the pump is primed it should start up without repriming in future – Hope this helps – Nigel

I have changed the fuel filter on a John Deere L130 garden tractor and the engine is still not getting gas. Is there a fuel pump or other part which would stop the flow of gas to carbuerator?
ANSWER : Underneath carb bowl should be a wire. Unplug it and remove ( unscrew) electric gas shutoff. Replace.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.
