You probably have a bent flywheel key. The timing is off and the engine.

You need to remove the pull cover and then the flywheel nut and lift off the flywheel and inspect the key. They are inexpensive to replace and available at local lawn equipment repair shops.

Good luck and be careful.

Model 944.361200.mower won,t start in colder weather,once temp gets above the70degree mark it will start,but blue smoke comes form exaust.mower will start right away every time once engine is hot.fresh gas...

I have a mower with a Honda 165cc engine that is temperamental as far as the initial start up is concerned.
Once it has started it always fires up first pull
The problem seems to be the gas is slow to reach the carb / cylinder
I have developed a ritual for starting up.
Open the gas tap.
Lean the mower back until the hand bar touches the ground.
Raise the mower and lift the hand bar so the back wheels are off the ground for a few seconds.
Fully open the throttle, Hold the ignition control back and operate the pull cord.
If it doesn't start first time I am usually rewarded with a promising fire-up.
Sounds wacky but works for me and used to spend 20 to pulls on the cord to get it to fire .

Sym red devil feels sluggish

    • 1 Locate the red button on the top of the handlebars. This is called the "kill switch." When you pull it up the engine can run; when you push it down, the engine will shut off immediately.
    • 2 Pull the kill switch up.
    • 3 Turn the key to the "on" position.
    • 4 Make certain the cord running from the key is attached to the steering column. This device acts in the same manner as the kill switch - the engine will run only when it is secured.
    • 5 Pull the start cord, which looks like an enlarged lawnmower pull-cord and is generally found on the right side of the machine.
    • 6 Listen to the engine - if it starts, let it get going slowly . If it "pops" but does not continue to run, try pulling the start cord a few more times. If you do not hear the engine turn over at all, proceed to the next step.
    • 7 Find the pull tab under the right side of the handlebars. This is called the choke - it often has a circle with a diagonal line through it. The choke helps to start an engine when the weather is very cold or the machine hasn't been used in a while. When using the choke, try leaving it on only long enough to hear the engine fire a couple times, then return it to the "off" position. A choke left on too long can flood the engine.
    • 8 Place the choke in the vertical position - this is called the half choke position. Pull the start cord several times. If the engine fires up, place the choke back down to its original position and let it slowly warm up. If the engine still has trouble starting, proceed to the next step.
    • 9 Pull the choke 180 degrees from its original position - this is called the full choke. Pull the start cord until the engine sputters a couple times.
    • 10 Replace the choke to the original off position and continue to pull the cord. The engine should fire up and settle into a steady hum, ready for fun in the snow.

I have been trying to turn on my chain saw. Ive pulled the handle back by the trigger gave a few pull on the rope. then i pushed the button in on the side also the push the button back in by the trigger...

The chainbrake should be activated when starting the chain saw. Activate the chain brakeby pushing the front hand guard forwards.b>Cold engine Start position, 1: Set the start/stop switch in the choke position by pulling thered control outward - upward.Decompression valve: Press the valve to reduce the pressure in the cylinder and makestarting easier. Once the machine has started the valve will automaticallyreturn to its original setting.Air purge: Press the air purge diaphragm repeatedly until fuel fills thediaphragm (at least 6 times). The diaphragm need not be completely filled.Grip the front handle with yourleft hand. Hold the chain saw on the ground by placing your right foot throughthe rear handle.Pull the starter handle, 4: Pull the starter handle with your right hand and pull out thestarter cord slowly until you feel a resistance (as the starter pawls engage)then pull firmly and rapidly until the engine fires.Push down the red choke control: As soon as the engine fires which can be heard through a"puff" sound, push down on the red choke control.Pull the starter handle (6): Keep on pulling the cord powerfully until the engine starts.

When yanking on the pull cord to start engine

Im guessing that you have started it before, so I guess , check that its not flooding ,pull air filter out see If you can see heaps of fuel in the bottom hole ,if you do take spark plug out pull cord a few times without holding start cable or you will catch on fire replace spark plug try starting ,no start still flooding take it to a lawn mower place ,float may have a hole in it , if not flooding, on the bottom of the cardy one brass nut , four holes find them clear then, start also a brass pipe going into the center of the carby is probable blocked

Gfs car was lacking power big time seemed like an electrical or timinmg issue so i yanked off one plug wire from the coil no change in sound,yanked the one behind that same thing(right hand side of coil...

it does sound like you have a plug lead out take one off the spark plug and plug another spark plug in to it place the plug to earth and crank the engine over there should be a spark there
also get a compression test done because if there is a brake in the head gasket between 2 cylinders then it will run rough and possably misfire

B & S INTEK 6.5hp timing issue

Your right but its not the timing but the decompression release. Has the oil been changed any time recently? theirs an arm on the camshaft the opens the exhaust late and releases some compression and as the motorspins it moves out of the way and full compression happens. The other thing that can happen is the flywheel key can be partly slipped ( timing off) these use an aluminium key and needs to be put back as one the other thing if any of the drive is loose so it can move on the shaft it'll act the same way. One other on an old but good engine carbon may have built up on the head or the piston making the compression higher. Most of the time if this is the case it'll only hit back hot

Bolt comes loose and rip cord is yanked from hand

  1. block off the blade and driver assembly with a 2x4 to keep it from moving
  2. remove the flywheel nut (regular hand force should be sufficient)
  3. tap the 3 holes on the flywheel (if they aren't already threaded) using 1/4inch 20national tap set
  4. remove the flywheel using a flywheel puller -- a harmonic balancer puller which matches the tecumseh bolt pattern on the flywheel also works using 3 1/4inch thread (20national, 2inch long) bolts with washers
  5. NOTE: (if the blade was removed/reinstalled, tighten the blade to manufacturer's spec of 60lbs) before installing the new flywheel key
  6. remove the sheared flywheel key
  7. clean up the flywheel (wipe off all the dirt and grease)
  8. install the new flywheel key (part 611004 for toro 20016)
  9. install the flywheel (pull the bail brake handle to get the ball-brake inside the flywheel)
  10. tighten the flywheel nut to manufacturer's spec of 37.5lbs
  11. prime the gas bulb, give it a pull and mow away

I have a 1981 ford with a 302 the cap has the firing order listed as 15786342 the dist has no elecs in it the pick ups on the crank it wont run right wired like this then when i switched it to 15426378 it...

This is from compcams website:

Firing Order, Small Block & SVO
This is one of the most common questions asked by our Ford customers. The firing order for the early 221-302 engines and the early 5.0 engines is 1-5-4-2-6-3-7-8. This is the firing order for all prefix “31” cams and is the standard replacement cam for all early engines. The later 5.0 engine and all 351 engines are designed to use the 1-3-7-2-6-5-4-8 firing order. This is the firing order for all prefix “35” cams, and cams ordered for these engines should use this prefix. Other than the firing order, the cams are identical. By changing the spark plug wiring at the distributor these cams can be interchanged.

I hope that this helps.

Please help me to stat this thing I have no manuel

When I first got my brand new RYOBI LIne Trimmer the *** thing just would not start. I was following the exact guidelines in the maual. First thing is, ensure you get right is fresh fuel correctly mixed accurately with 2-stroke oil. Some machines are more temperamental about the mix. 2. Set choke to COLD, press bulb 8 times (once you see fuel enteing the clear bubble reservoir) 3. Switch on power. It's amazing how often I've pulled the cord with that red button off. Dont think you cant do it to. 4. Pull the cord gently until you feel resistance. Let it gently recoil, then in one non-aggressive move, holding down the unit with your other hand, pull it out at constant speed. Do not yank! If (or rather when) it doesnt start, pull the accelerator trigger a couple of times only, and repeat procedure "4". Don't press bulb again too often or use the trigger too early or you will flood the engine. When I couldnt get my strimmer to start at all, I got this advice from an online engineer, it fired up *first pull*.

If it's not starting after a winter rest, did you store it empty of fuel because that is always wise. Discard old petrol mix and start with new. Hope that has helped.
