SOURCE: I relpaced the fuel lines on my Mccullough Eager ****** leaf blow

ok then these are the low and high speed adjusting screws. first make sure the spark plug is clean of buildup or new . what you need to do is first try to get it to idle with the low adj screw. now im not sure which ones which so try one and if it makes no difference during idle then try the other. start it if it dies turn the screw , repeat this until you get the right sound and steady idle.once you figure out the low screw trun it all the way clockwise then turn it counter about 2 turns. then tune the idle from here. you want it to have a steady sounding idle. now the idle sounds good use the high screw to adjust the throttle. give it about half throttle and turn the high screw until it sounds steady here. then go to full throttle and turn high screw until it sounds steady here. now it should sound steady at idle and throttle. and try not to trun the screws more than 1/8 to 1/4 turn at a time,especially the high, you dont want to blow it up. lemme know how it goes

SOURCE: I have a mcculloch backpack

I am assuming the carburetor is ok. Check your spark arrestor. This is a screen located at muffler exit. Usually just a screw holds it in, pull it out with a pair of pliers and clean or replace. I usually hold it with pliers and burn it clean with a little bernzamatic torch. If that doesn't fix it probably a carburetor problem.

My 03 gmc yukon has sat for a day i went to get something out my truck and it smelled like gas inside

Cycle the key on and off or simply start your vehicle for a moment and check for any gas leaks. Because your vehicle is a GM, the lines tend to rot away along the frame right where the plastic clips are that hold it in place. Start from the engine and work your way back. I'm sure your find a bad section on steel line. Also check to see if you have a cabin filter and replace as well. I hope this helps you. Good luck

Replace fuel line on husqvarna 142

You need to remove the carb to do this, remove the top cover, remove the two screws holding the air filter on and remove, remove the two 10mm nuts holding the filter back plate and remove, remoce the two 7mm headed screws secuting the carb, remove the two cross head screws holding the bottom of the bracket, the bracket will now come away along with the carb, unhook the fuel hose from the carb, now grab the fuel hose through the fuel filler hole, pull the hose with the filter out through the filler hole, take a new hose, slice one end into a long taper, push the taper through the hole in the crankcase floor and into the top of the tank far enough to be able to grab the end with a pair of long nose pliers through the filler hole, pull down into the tank, trim the end and refit the filter.

Both lines from carb to gas tank rotted off inside of gas tank

These lines need to be replaced. If you can do it yourself go to shop and buy about 18 inches of line, also new filter. It has been my experience that you will probably end up having to go through the carb.

Have a weedeater gt1 15 trimmer how do u get the gas tank apart to repair the gas tubing

You will not need to remove the gas tank or take the gas tank apart. Follow these instructions:
1. Disconnect the fuel line from the carburetor. You may need to cut the line pull it off.
2. Push the fuel line back through the gas tank. At the end of the fuel line is the fuel filter/weight that should be moving around within the gas tank.
3. You should be able to pull the filter/weight out of the fuel tank through the neck using a needle nose pliers. Insure the fuel filter is cleaned out before you re-assemble.

Note: The fuel line that you use as a replacement must be the same diameter of the fuel line you are removing. If you cannot find the fuel line at your local mower shop, try Lowes Hardware as they do stock it in the lawnmower section.

To reassemble: Take about 7 inches of correct fuel line and cut a 45 degree angle cut at one end. That end is threaded back through the tank through the small hole. Push as far as you can and then reach in and pull it to the neck. Cut the straight, attach the filter/weight and pull the line back through.

Not geting any gas to the eng.

look in the gas tank and see if line is rotted.
next look at small filter in end of line to see if it is plugged up.
when you push the primer bulb you should see gas in it.
if not then you might have to replace all the gas lines and primer bulb.

I need to know how the fuel lines are hooked up in my ryobi gas trimmer. All of the fuel lines rotted out. I took them out and I need to know the correct connection sequences (what goes where).

line runs from little filter in tank to carb.
line from carb. to primer bulb
line from primre bulb back to gas tank.
lines are 2 sizes
need to cut at angle end of lines in tank so you can get them thru holes
and grab with needle nose plyers and pull them thru.
make sure you put the little filter on end before you pull line thru and leave
enough so filter can move around the whole tank.
second line in tank is smaller and need to cut and pull it thru hole in tank to primer bulb

Reattaching fuel line to gas tank.

Get a new line the same size and length of the old one. Get the filter out of the tank. If it is as I think, it has a barbed end that goes into the outlet hole. Take your new line, fit it onto the filter end and make sure it is all the way on. Take the other end of the line and cut a taper on the end. Thread the end through the tank, into the outlet hole and aissist it so your filter sticks through the tank hole. There was a ring on the outside of the tank, on the line. Take that ring and run the ring over the end of the tube up to the filter bottom. Make sure it goes all the way up to the bottom, and tight.Square off the end and slip it onto the carb...Good luck...Lee

How do I replace the fuel filter on my 2000 Volvo S80

The gas filter is located passenger side just forward of the rear axle. The band that holds the gas filter in place is a pinch band that has a nut welded/formed into it on the back/top side. A 12 mm bolt holds the band in place. The top of the band has a bracket that hold the return fuel line - this just pops off and the return fuel line can be reattached once the filter has been replaced. If your filter has never been replaced there is masking tape covering the pinch connections at both ends of the filter. Remove the masking tape. You need to put a pan under the old filter to catch any gas spillage - it will be minimal. Also the new filter comes with plastic caps on the ends of the new filter - you will want to use them to plug the old filter connectors so you need to take them off the new filter to have handy. Ther is a T off the inlet gas line that has a cap on it - remove the cap and press the needle in the T to relieve any pressure that is on the gas line - If it has been setting for an hour there will probably be very little if any pressure on the line. You can skip messing with the T and you will see about an ounce of fuel that will come out of the filter when you remove the hose.

To remove the connectors push the connector ring away from the filter housing. (I did the front first because I had more room). I used a paint can opener to help pry the hose away from the filter - it is shaped like a can opener but without a cutting edge - a large flat screwdriver would perform as well. It is a tight fit but once it starts to move it will come off. Once the hose is off use the plastic caps you took off the new filter to help hold the gas in the old filter. After removing both ends remove the holding band and place it on the new filter. The two lines will go back on easier than they came off, just push them onto the filters nipples. Put the 12 mm OR 10MM bolt back into the pinch band and reintall the return fuel line.
