M842 chainsaw wont start when hot


I suspect your warm start procedure is the fault, the manual is not correct IMO. Any choke on a warm engine causes flooding, try this, if no better post back or return it for warranty replacement.

Start Procedure
Cold:
  1. Ignition on/off to on.
  2. Set compression release – optional step even if saw is equipped with a compression release.
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
  4. Set compression release – optional step even if saw is equipped with a compression release.
  5. Push (open) choke pull starter until it starts. (usually first pull).
Warm:
  1. Ignition on/off to on.
  2. Set compression release – optional step even if saw is equipped with a compression release.
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull).

It Won't Start


Read your manual very carefully. I think it is flooded. Read line 3 (cold and warm). read them again. Read 5 in your manual. Most overlook the attempt to start , continue with the choke closed and the saw floods. You have an additional visual indicator, watch the decompression valve, when cold; once it pops turn off the choke. The warm procedure is very close to mine.
Start Procedure
Cold:
  1. Ignition on/off to on.
  2. Set compression release – optional step even if saw is equipped with a compression release.
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
  4. Set compression release – optional step even if saw is equipped with a compression release.
  5. Push (open) choke pull starter until it starts. (usually first pull).
Warm:
  1. Ignition on/off to on.
  2. Set compression release – optional step even if saw is equipped with a compression release.
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull).
If it still will not start return it for a replacement or your money back. Anything you do may render any warranty invalid.

Did you purchase this in a big box store? What is your elevation?
All new saws regardless of maker are set to run extremely lean to meet EPA mandated air quality standards. They are also fitted with a device to restrict richening the carburetor beyond initial factory settings this too required by the EPA. Most big box stores put them on the shelf and sell them to the consumer with no thought of how elevation may impact saw performance or longevity. Homeowners usually are not concerned about changes in the saws performance until it quits operating. This combination results in many destroyed saws and homeowner saws of most brands being called trash!
Find a local chainsaw seller/mechanic. If they pull a saw off the shelf and hand it to you without making some adjustment or minimally ensuring it will run hand it back and leave. You can get this service at a big box store cheaper. Find a different seller/mechanic and try again. A good dealer will help you arrive at a saw that will meet your needs. He will ensure it runs properly and you have an understanding of how to properly operate it. Should a problem arise you have somewhere to go and if you were courteous with your dealer someone in your corner helping you rectify your problem.

It starts and runs but when you turn it off it won't restart.


I think the warm start procedure in the manual is causing it to flood. Try it like this, if you continue having problems reply below and we will try something else. PLEASE read #3 (Cold and Warm) a few times before attempting to start. Try it without 1/2 choke (your manual); completely open.
Start Procedure
Cold:
  1. Ignition on/off to on.
  2. Set compression release – optional step even if saw is equipped with a compression release.
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
  4. Set compression release – optional step even if saw is equipped with a compression release.
  5. Push (open) choke pull starter until it starts. (usually first pull).
Warm:
  1. Ignition on/off to on.
  2. Set compression release – optional step even if saw is equipped with a compression release.
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed or at 1/2 choke position.
  4. Push (open) choke, pull starter until it starts. (usually first pull).
Hope this helps.

Start at 1.5 CCW form lightly seated then tune for performance like this:
Carburetor Adjustment by Madsens.com
http://www.madsens1.com/saw%20carb%20tune.htm
CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.

There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too.

I think your starting procedure may be the cause of flooding. Flooded is the #1 cause of hard starts in 2-cycle engines. Read carefully the recommended start in your manual. most miss the second note. It should be similar to this (read 3, read it again):
Warm start in the manual says 1/2 choke BS. Close choke, (sets fast idle) open choke, pull rope.
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4).
  4. Set compression release – optional step even if saw is equipped with a compression release.
  5. Push (open) choke pull starter until it starts (usually first pull).
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) – Do not pull with choke closed.
  4. Push (open) choke, pull starter until it starts (usually first pull).
If you still have trouble reply as you did before. I will get back to you. HTH

Mcculloch 3516 chain saw, does not always start.


It must have spark, fuel and compression to run. Your task is to figure out which is missing.
Sometimes electrical components quit operating once beyond a certain temperature. Does it always start cold and become tempermental when warm?
IMO most hard start problems on a chainsaw with a good fuel delivery system are flooded.
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually first pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) - Don’t pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull)
The 3516 is a MTD McCulloch (Chinese). These saws are in a class by themselves. Good Luck

2ooo yamaha stops running when it gets warm any


The carb probably is dirty or has some water in the float bowl, if you can first remove the float bowl without removing carb to see if there is any water or foriegn matter in the bowl try not to splill gas while removing so you can see what is in there

Engine dies when choke is relased


This means the engine is running lean the choke lessens the airflow to give it a richer fuel mixture (more parts gas to air ratio)
*first you should check the spark plug--
This can be caused by faulty gaskets.
I would also make sure the floats work and that the needle and seat (connectet to the floats) work also the needle tip can become worn over time it should make a v shape.
when you clean the carb you should get every jet and hole with carb cleaner and you should use high air pressure through the jets and clear any grime clogged in the middle of the jet passages.
make sure you have the right air to fuel mixture (32:1)
be careful an engine with the choke on too long can strip away the oil lubrication protecting the cylinder from being scored

MOWER RUNS FIVE MINUTES THEN STOP AFTER IT WARMS UP


Check your automatic choke ... a cold mower needs more choke, and the auto-choke should release when the motor warms and runs smoothly. If the choke is sticking, the motor will die when it gets warmed up, then start again after it cools down.
