Use a hotter spark plug. They do have different heat ranges.

I have PAS225 ECHO weed eater. will start easy but will only rev up when operating the choke. Has no power

You still have a clogged jet in the carb or a restricted fuel flow, where that is a mystery right now.

I have a psa 225 echo weed eater. The engine readily starts but will only rev up using the choke lever back and forth. No power. What's my problem?

Carb or filter
. replace fuel filter in tank while checking both pickup and return fuel lines.
remove carb and disassemble cleaning all parts with carb cleaner and some soft air blow . look for small screen its round and about 1/4 round in carb these are so small that the gas that's available gells and plugs the openings . try to use non-ethonal high octane gas and use echo 2cycle oil .

I have a 2010 ktm 65sx ran like a top last year this spring got it out ran good all of a sudden bike starts good but it seems like it starves for fuel on the low end when it gets in the power band it takes...

Thank you for contacting FixYa with your inquiry.
Low power or stalling at start is usually air/fuel related. You have taken care of most of the things that effect the bottom end power band. Some other things you might consider:
  1. Check the air vent tube on top of the tank to make sure it's not pinched or restricted.
  2. Clean the fuel tap. May have sediment or debris. Some have a filter screen. Clean it.
  3. Clean the air filter and air box. Check the rubber boot for cracks or air leaks. Clamp??
  4. Exhaust system - Check for leaks or fiber fallen from the muffler.
  5. Check the diaphragm or reed valve for cracks or reed problems
  6. Check the timing or fault with the ignition system. Is something loose.
  7. Screw in the idle jet all the way and back it out to 1 1/2 turns.
Jetting: (Tons of options with a Mikuni) In general, the main jet is for high rpms and top speed running. Needle effects the mid range to about 3/4 throttle. Idle jet effects the bottom end. 3 sizes exist 20, 25, 30.

My kx 2005 was runnin great them started bogging randomly changed reeds top end and cleaned carb...

Well - not knowing the condition of the bike it could be a lot of things. I would start with a fresh spark plug, fresh fuel and a clean air filter. You say you already did the carb, reeds and top end - good. I assume you set the float level correctly. Did you pull out the petc0ck from the fuel tank - theres a filter that might be plugged up. Check your exhaust system for plugs - I've seen mice nest in pipes over the winter. If all this fails, look into your power valve system to ensure it's working and adjusted properly. If so, then do a leak down test - you might have a lower end leak. That's the best I can do without seeing or hearing it run. Hope this helped!

Dead pw 50 and sad boy.

Many things could cause the problem. Let me see if I can help out.
You have spark, but is it enough spark? A weak battery can rob power from the coil so only a weak spark is present. Get a new stock NGK spark plug to eliminate the possibility of a problem plug.

It is good that you cleaned the carb because that would be my second target. Reset the air and idle screws. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Clean or replace the air filter and be sure the bolts are tight on the carb manifold. INSTALL AN IN-LINE FUEL FILTER. Let the float bowl fill then start the engine. Set the idle speed with the idle screw.

Remove the cylinder head. run the piston down to the bottom of the cylinder. look inside the cylinder. On th carb side (intake) you will see an intake port > a large hole that lets gas into the cylinder. Now look at the exhaust port. It is possible the exhaust port is pretty plugged up with carbon. The intake and exhaust ports should be approximately the same size. Are they? If not then remove the muffler and take a screw driver and plastic hammer and knock the carbon into the cylinder, thus enlarging the exhaust port to its' proper size and allowing the exhaust gases to escape. Vacuum the carbon out of the cylinder. De-carbon the piston top and the cylinder head.

Get back to me and tell me what you find. If more is needed we will go further.

2003 Suzuki RM 125 with no power band.

Scatter gun approach > thoughts to check out > > >
Clean and dry the air filter? Go back to a stock main jet, at least to check things out? Are "O" ring seals on the main jet going bad?Partial internal collapse in exhaust (remove exhaust pipe & do a quick run down the alley), Install a new stock NGK spark plug, Be sure battery connections are clean and tight, Be sure intake manifold and carb are good and tight.

Hope this helps!

1994 suzuki RM80R: problems with the carb loading

Sounds like trash in the gas supply is holding the float needle open causing the float bowl to overfill. Remove the petcock from the tank and clean out the water trap bowl (some petcocks don't have a bowl). Drain some gas from the tank through the petcock hole to help clean trash out of the tank. Install an inline fuel filter
between the carb an the gas tank.

Now clean the carb one more time using an air hose to blow trash out of the float seat and then blow out the fuel line as well. Be certain the float level is set at the proper height. This should solve the problem for you.

Please rate this solution as a "FixYa" if this solves the problem. Thanks!
