2003 yamaha 1100 has been sitting for 2 years what should i do ?

Take out the plugs and spray a good long shot of WD-40 into the cylinders, replace the plugs, but leave then disconnected from the plug wires. Gently kick start or electric start the engine. If it will ot budge, the engine is seased and will require dissasembly and serious rebuild. If it does move and frees up, drain the old gas, replace it with fresh gas and replace the spark plug wires and attempt to start it. If it starts, don't' be alarmed by it smoking at first, that is the WD-40 burning off. If all is well, the smoking should subside and the idle should settle down. If the smoking worsens, turn it off and take it to the shop. I can not be held responsible for any damage that occurs to this engine, try this at your own risk. Make sure you are in a well ventilated area too. Good luck, be careful.

I have a 1993 pick up hardbody' a lot of black smoke coming out and idle is rough..any suggestions on what may be the problem?

With the black smoke, it sounds like it's running rich (too much gas going into the motor). Remove a spark plug and take a look at it- if it's all black and sooty, then yes, your motor's running too rich and you need to lean out the fuel mixture. I'm not positive, but that truck probably has a carburetor and you could do the adjustment yourself, with a little help from a shop manual. If it's fuel injected, you'll want to take it to a shop or a friend that knows what they're doing to get it adjusted right again.

If the spark plug has little tiny clumps of stuff stuck to it you're burning oil, and that's a bigger problem. An oil leak means a fairly major engine rebuild is in store for you. If it is burning oil, I'd just drive it like it is until it eventually conks out or something else goes wrong on it. Unless, of course, the truck is special to you and worth investing in an engine rebuild...

Good luck!

What is H and L carb setting for a Poulan P3314

The "L" is your idle setting and the "H" is the wide open fuel setting. After the engine starts and runs a minute adjust the "L" to the smoothest run setting the go full throttle and adjust the "H" the same way.

Hope this helps.

Bike splutters then takes off..bacfire when starting sometimes..gets beta if you thrash it..hav narrowed it to the carb, an was after the stock settings cr80 2001

i take it the carb isnt the original one? well you can still set it up for the bike take the carb of and remove the bottom and check the floats there shouldnt be petrol flowing out of the overflow pipe when the bike is running when you have done that take the top of the carb apart and remove the needle valve from the top its connected to the throttle cable blow down the jets to clean them out re assemble the carb
there is 2 screws on the side of the carb 1 is the air screw the other is the tick over turn them both in till they are tight then turn them 2 turns out
when you start the bike it might run fast at idle or backfire if it does adjust the top screw for tick over(idle) the bottom screw for running better

hope this helps

I adjusted the chok and it would only run with it on. I put it back and it would only run with the trottle twisted. then it suddenly went dead and would not start at all. now the battery is dead. got new...

You will need to most likely rebuild the carburator [s] or you have blockage. Try spraying WD 40- in to the intake - if the bike runs poorly but runs - replace the fuel filter. I am not sure where they are on this model but any dealer will direct you to them as they would me. Take down the Vin # - call the local dealer and ask about RECALLS - this can save you thousands over the years - do this on all your vehicles every 6 months or so.
You will need to most likely rebuild the carbs as partial blockage or a dead fuel pump is the problem and the only repair is to replace or rebuild.

Chain saw

Check the fuel filter, air cleaner, and muffler for plugging. Check the fuel line for decay or other damage. Make sure you have fresh fuel mix in the tank (40:1) using a modern synthetic oil made for saws. If the above doesn't help, you will need to remove the carburetor, clean it inside and out with spray carburetor cleaner and check the lower chamber diaphragm for flexibility--no holes or cracks. If the two jet needles have been disturbed, turn both screws CW to stops (lightly), then back out CCW 1-1/2 turns each. This is a basic setting which should allow the engine to start and run. Start the engine and allow to warm up, then pull the throttle full on and adjust the H needle CW until the engine starts to speed up, but 4-strokes. Correct adjustment is when the engine 4-strokes unloaded, but immediately 2-strokes when cutting. Release the throttle and adjust L needle CW for better idle, yet allows the engine to 'follow the throttle'. Adjust idle speed screw so that the chain stops turning, but the engine continues to run. Hope this helps!

Need to know how to rebuild the carb on a 3.0 hp

The carb sounds like a vacu-jet, very easy to rebuild. Remove it from the tank but be careful not to damage the siphon tube. Then make sure to check for foreign matter in the tank (big problem with this system), clean and flush it. The idle screw is easy, the other is set by going from idle to full throttle quickly and adjusting it just so it doesn't stumble

Poulan 6.75 Lawn mower will not start

Remove spark plug, clean and dry. Replace plug. Remove air filter. Spray WD-40 into carb opening; one second blast. Turn over engine, (pull handle). Engine should start briefly and run for 3 seconds.  If not, you are not getting spark to spark plug. If engine starts, you have a dirty carb and you can buy a rebuild kit from manufacture.
