Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please do not forget to rate me, Thanks
Good Luck, I hope this helped

Have a 2004 v6 3.5 rodeo hesitates while accelerating. Have change the throttle body made no difference.


Hi this could be an air leak in a vacuum hoses or the hose from the air filter to the throttle body may have a small split and sucking air
it doesn't take much air suck to cause a problem
Good Luck :)Also i must add a possible fuel supply problem or dirty injectors.or possible lack of pressure in the fuel rail.only some of the scenarios but most likely one of them will be the problem.

Troy-Bilt Hand-Held Blower dies when warm and throttle wide open


You reported that most of the items I would've suggested, you have checked...
Good job.
A couple more things:
  • Replace fuel filter, it's in the gas tank
  • Check and clean the Spark Arrestor screen at muffler, when they plug up, it's a major restriction to exhaust gas flow
  • And check and adjust High/Low screws at carburetor, video attached.
  • And clean or install rebuild kit for carburetor
Good luck...

2002 IDEL PROBLEM


  1. check the air filter, good and clean?
  2. spark plugs in good working order?
  3. clean the idle air control inlet on the throttle body
to clean the idle air control port
  1. find a helper to push the throttle
  2. remove the inlet hose from the throttle body
  3. using a suitable spray cleaner spray into the throttle body and have your helper rev the engine to keep it from stalling. Don't spray to constantly just a quick one or two second squeeze
  4. let the engine idle again and see if its stable
There are a few other possible causes such as an old fuel filter or a fuel pump issue

Car doesnt accelerate when gas is pressed it bogs and jerks motor is on but idle is low


This problem could be caused by anything between
the gas pedal and the throttle. Talking about spark
plugs, air filter, fuel filter, fuel injectors, engine control
unit, egr system, intake manifold air leak and so on.
You can try Spark plugs or a couple of bottles of
gas tank additive to clean you fuel system. Had a
98 with dirty injectors which took five applications
to clear them. Other wise Chrysler will have to hook
up and look for fault codes. If no ck engine light is
on try the simple fixes first (basic tuneup).

Blower not running at high rpm when full throttle. Cleaned air filter, gas vent, gas filter and spark plug. Blower is 3 years old. Have not bought any new replacement parts.


Try removing the muffler and look inside of the exaust port, you should be able to see the piston in the full opening of the port. If you can, try starting and running at wide open throttle. If it runs fine( a bit loud, so wear hering protection), then you have a plugged or partialy blocked muffler or spark arestor. Sometimes rich mixture can cause excessive carbon build up.

Hope this was helpfull.

Has trouble accelerating sounds like its missing and is bogging


Sounds like a timing problem to me. I would look at this first. It could be fuel related too. The old carburated engines would act like this when the accelerater pump on the carb would go bad.

Good Luck
