I would first check the spark plug and air filter. If the air filter has grass or dirt packed in the folds of the paper element, replace it. Also if the spark plug has a black charcoal like substance on it, it will need brushed off. The spark plug can be removed with a 13/16 deep well socket. If the unit will still not start, there may be water in the fuel tank. Drain the fuel tank and empty the contents of the fuel bowl on the carburetor. The carburetor fuel bowl has a nut on the side of it, it can be loosened with a 10mm wrench. Let it drain out completely, tighten the nut on the fuel bowl, and add fresh fuel. If it will not start at this point you will need to have the engine serviced. This can be done at any Honda Power Equipment repair shop. They may not want to work on it since it is on a Husqvarna mower, most will tell you that the only thing that they will work on is the engine. Alternately you can take it to a Husqvarna dealer and get the mower serviced there.

Gas coming out over flow hose on my cbr 600 f2 and to much pressuer in gas tank


Check the carb float levels and that the tank breather is clear. Pressure will build in a petrol container just from it being shaken, but heat will increase the pressure. The breather is usually a small hole in either the filler cap or the filler cap mount. When you see the MotoGP bikes with a pipe coming from the Filler to the fork pivot, this is the breather pipe.

1991 80'' heritage softail classic. Blew oil tank filler cap off


Hi, Kelkins1234 oil level readings are taken when the engine has reached normal operating temperature and the usual suspects are:
1. Overfilled oil tank dipstick reading should at or below full.
2. If the sight glass is full you are running to much oil.
3. Excessive blowby caused by worn out piston rings.
4. Piston rings never properly seated.
5. Faulty breather valve or system.
6. Pinched or clogged breather line/hose.
7. Clogged or failed oil filter.
8. Contaminated oil dirt-rust-water etc.
9. Excessive oil foaming.
10. Wrong oil type not designed for your bike.

I have a husqvarna 345 run for a few cuts then stops.


either blocked fuel filter in the fuel tank ( hook out and replace ) or the fuel tank breather is blocked thus causing a vacume in the tank, to prove this, when the saw starts to die slacken off the filler cap, this will allow air into the tank and it should pick up again, the breather is pressed into the tank on the r/h side rear.

How do i check fluid for convertable top


"How do I get the air out of my hydraulic system"?
  • Remove the reservoir plug on the motor pump. Leave the plug out and do not put back until you have finished.
  • Fill the reservoir 3/4 full with fluid (to the bottom of filler plug hole). Put a rag under the hole to catch overflow that will occur as system fills.
  • Run the pump for 15-20 seconds. Stop. Check your fluid level and refill to bottom of filler hole. Continue running the motor in the same direction for an additional 15-20 seconds. When the top gets to the end of cycle, check your fluid level, fill to bottom of filler hole, and run the motor in the opposite direction.
  • You are literally running the top all the way up and down sereral times. Checking the fluid level as you go and fill as required, leaving reservoir 25% empty.
  • When you are no longer able to add fluid, put the top in the down position. Check the fluid level one last time, should be to bottom of filler hole. Put the plug into reservoir.

    I want to check the engine oil level for previa 2.4 petrol 1995



    OIL LEVEL CHECK Every time you stop for fuel, check the engine oil as follows:
    1. Park the vehicle on level ground.
    2. When checking the oil level it is best for the engine to be at operating temperature, although checking the oil immediately after a stopping will lead to a false reading. Wait a few minutes after turning off the engine to allow the oil to drain back into the crankcase.
    3. Open the hood and inspect the level of the engine oil tank. The fluid level on the tank should read between FULL or F and LOW or L.
    4. If the level is below the LOW or L line, remove the cap and add enough engine oil to reach the FULL or F line. Fig. 1: Fill the engine oil tank located under the hood first 90911p07.jpg
    5. Install the oil cap and hand tighten.
    6. After filling the oil tank, remove the engine access hole cover on the drivers side. Fig. 2: Make sure the oil tank is to the F mark 90911p15.jpg Fig. 3: The oil dipstick is located under the driver's side engine access hole cover 90911p83.jpg Fig. 4: Place your finger through the hole and pull straight up to remove 90911p84.jpg
    7. Remove the engine oil dipstick and wipe it clean.
    8. Reinsert the dipstick, push it in as far as it will go, the pull it out and look at the level on the end.
    9. If necessary, insert more oil through the oil filler cap next to the dipstick, this will completely top off the system. Fig. 5: The oil dipstick has two markings for level check 90911p85.jpg Fig. 6: To fill the crankcase, remove the engine oil filler cap 90911p86.jpg prev.gif next.gif

    My auto fiat punto smells of petrol after i put some in when i start driving what causes this and how can it be fixed


    sounds like the fuel filler cap breather hole is blocked.also when you top up with fuel always close the windows/doors as benzine in gas is the most poisonous substance known.you should never stand upwind when filling up.(check out benzoates on wiki)

    I smell gas fumes coming from my car when i park and turn off the ignition


    normally fumes come in to vehicle when stopped because of oil leak from rocker cover but check your fuel filler cap seal etc and also incase the tank is leaking just have a sniff at the rear of the car if its the filler cap or tank filler you normally get smell when tank is nearly full and been around a few corners the fuell filler nect becomes pourous and just spills out a bit if so will need replacing .but most time its an oil leak from rocker box or engine

    Difficulty starting


    darn thing wouldnt start after I fueled it up. After sitting for 10 min it fires right up and runs great. When starting cold it fires right up with no prob. Someone told mevapor lock is my issue this sound right ? and if so what is vapor lock and how do I prevent it ? thx all for your support.,The vapor lock situation happened to me a few times with my 748, so it CAN happen. To test this theory, just fill your tank to 1/2 of what it normally holds, next time you fill it. Or pop the cap off right now and let it sit for 10 minutes and close it back up again. Al your doing is releasing the pressure on the system. Will this do any good? Well, had always been filling my tank too high and once I realized that popping the gas cap, would release the pressure, I never had a problem after.,,,
