This is how to clean the fuel passages in the carb for a honda type OHV engine.

Here is what you need to do:

1. Fuel selector off
2. Remove float bowl mounting screws and nut
3. Remove the BRASS Jet / Orifice in the very bottom of the venturi tube inside the pickup tube. (Flat blade screwdriver) Hold the Orifice up to the light. You should see a pinhole. If it is not clear clean the orifice but do not force anything through the hole.
4. Underneath the Orifice there is yet another BRASS tube that you need to remove. (Flat blade screwdriver) Make sure all of the holes in the tube are clear. The tube will be over 2 inches long. Clean it and reinstall it.
5. Reinstall the Orifice.
6. Using a catch fuel container turn on the fuel selector. Fuel should flow at a good rate. GENTLY lift the float assy level and make sure fuel flow shuts off. When you drop the float again fuel should flow.
If you do not have fuel flow at this point the needle and seat will need to be inspected. Fuel selector OFF.
(The following procedure is to be done only if there is no fuel flow with fuel selector on.)
a. Remove the silver float pivot pin retaining screw
b. Drop the Float down (The needle will come off with the float. NOTE the position)
c. Inspect the tapered rubber of the needle If should be pointed. If it is not pointed then the rubber tip is stuck inside the seat.
d. Clean the seat hole ONLY if obstructed. (Easily damaged)
e. FUEL Selector on then off fuel should rapidly flow through the needle seat.
f. Renistall Float and needle making sure to get the pivot / hinge pin installed correctly and reinstall the silver retaining screw.
g. Fuel selector ON. Raise and lower float checking for free movement and fuel flow.

7. If there still is no fuel flow at this point remove the fuel hose from the carb and check fuel flow. If no flow check that gas tank exit hole, fuel filter (if installed) and the selector valve assy for obstructions. Reassemble connections.

FUEL FLOW IS GOOD

8. BEFORE you install the float bowl inspect the bowl nut. There are 2 holes in the side of the nut where it screws in to the bottom of the carb that must be clear.

9. Install Float bowl mounting screws and nut. Check for leaks.

10. Test engine.

That should do it. (carb cleaning 101)

If the above does NOT apply to your engine then please respond with the engine type model number off of the air shroud just above the spark plug. ALL of the type model numbers will be needed. Also in some cases the serial number.

Zelmo use 10w30 weight oil and just put in enough to reach the full mark. In an air cooled engine I highly recommend you use Full Synthetic oil. It performs much better than conventional oil in an air cooled engine. Change the oil once a year.

Go to www.ordertree.com. The flailblade is p/n 719-0329, The shredder blade is p/n 942-0571, The chipper blade is p/n 981-0490.
Replace them you have to take casing off the unit to get to them.

Hi
First you need to check for spark at the plug if you have spark remove plug put a tea spoon full of gas in the plug hole reinstall the plug and try to start. If it starts for a sec the carb or fuel line is clogged and needs to be cleaned.

sounds more likley to be a dirty jet in the carb,
the brigs and straton engine never did have a very good carb fitted wip off the flote bole and clean out carb and all the jets,,,

take the 4 bolt out of the starter housing, lay on table take the old rope out. turn the center rope pulley counter clock 6 to 7 full rotation's so the center pulley hole lines up with out housing hole(steck a screw drive throw to hold pulley in places). feed the rope from outer throw the center tie off. let the pulley dr ow the rope in. pull the rope out a Little tie off to handle

It sounds like the blade brakes are worn out. If you look under neath the frame,where your feet rest, you sound see an arm with a brake pad on it.
It may be time to replace them.
Go to www.precisonope.com, put your information in under OEM parts. It will give you a diagram and parts list. You can find your part number for the blade brakes.
Good Day.

The blade(s) should have usually two bolts on them depending how many blades you have. Mine only has one blade held on with two bolts and that is only on the side that cuts the larger branches up to two inches in diameter and should be sharpened on a grinding wheel because it has a specific angle to it. The other side that chips smaller branches and twigs it a type of flailer, meaning pieces of metal just swinging around to mash up the sticks and do not need sharpening.

Clean out the carburetor float bowl and main jet. Sounds like dirt or moisture in it

Sounds like the carb is gummed up. Do a complete carb cleaning and see if it helps.

sounds like the carb is gummed up. You probably need to do a complete carb cleaning.

if its a briggs and stratton engine your ignition coil might be faulty... you should be able to get a 2nd hand unit at your local mower shop... or.check that your throttle control lever is to run position as it has a stop switch on it earthing out the ignition

MTD manuals are here:

If the starter seems fine and all the wires are ok. Including the ground is securley grounded on the battery then it would have to be the voltage regulator only thing left that sends power to start it

If a small engine wont start its usually one of two problems, its not getting gas, or its not getting spark. easy way to find out if its getting a spark is to remove the plug, put it back back in the connector and just let it hang down while you try to start it. you should see a bright blue spark, if you dont try changing the spark plug. if its getting a spark come back on this site and i'll help you trouble shoot it.

Squirt a couple of spoonfuls of oil into the spark plug hole to increase the compression as it has been sitting so long. Also squirt a little starting fluid into the carb. and give it a shot I think it will start. Hope this will. donnyb60

I believe it is part of the systen shut off. Should be connected to the motor (ground).
Hope this helps you

sounds like water in the carb bowl - loosen nut on bottom of carb to drain and retighten then try to restart

Maintenance (excluding the power plant) Your primary maintenance concern with chippers and shredders is their knives. You can re-sharpen chipper knives, whereas you can reverse shredder flail-type knives when dull but you can not re-sharpen them. You must sharpen chipper knives with special sharpening equipment because they are made of high-carbon steel. Maintaining sharp knives can lengthen their life and the life of the machine by keeping power requirements low. An over-dulled or chipped chipper knife will need extensive sharpening, which will remove a large portion of the blade. This obviously will shorten its life. As soon as a blade is slightly dull, you should sharpen it to minimize the amount of blade-material that you remove. All knives need sharpening at the same time to keep them in balance-even if only one is worn or chipped. Also, you must use matched sets to keep the knife the same distance from the anvil for proper chipping and feeding. After removing the knives, clean the area where they are fastened with a wire brush to make sure they will align correctly. Be sure to torque the knife bolts to their proper specifications. You will need to examine the anvil and be sure it maintains a good, square edge. Occasionally, you may need to remove and sharpen it.
