Definetly an air leak, I believe what is happening is where the inlet manifold joins the cylinder it has a poor joint which when cold is contracted and when engine heats up the joint expands with the heat,sealing the leak, ie causing the fuel/air mixture to become rich enough for scoot to run.

2001 evenrude e225 will not start normal but will with ether


Do not use Ether on that engine!!!!!!!!!!
Right now the carbs are gummed up and need cleaned. Ether can blow your motor. You can get some throttle body cleaner or take it in and have carbs cleaned.
Just don't use ether

Blower not starting


Try a shot of ether in the carb. If it still won't start, check the spark. If it only runs on ether, then it is not getting fuel. At this point, you should rebuild the carbureator.

Hi I have a 97 partner k700 concrete saw. It will not start and seems to be putting too much fuel in cylinder wen trying to start it. The carb has been rebuilt and has new spark plug. The carb does not...


This sounds like the rubber tipped inlet needle is leaking on its seat, you can try another needle, however if the seat is pitted it will need a new carb, you need to do a pressure test on the fuel inlet of the carb, with a small pressure ( 2 psi approx ) there should be no leakage

I have a coleman powermate 6250 generator it get gas and spark and oil is fine but wont start


Lets see, Do you have any ether or old school lighter fluid? If you use ether spray a little into the air intake just before you pull the cord for a start, if it starts you have a carb problem. Same for the lighter fluid, remove the spark plug and squirt a small amount down in the cylinder, again if it starts you have a carb, probelm. Take the carb. off the engine take note of the rods and springs, take a picture get it in good focus so you can put it back together. Take the fuel bowl off the bottom of the carb and clean the jets and all see if that will help.

New battery re-charged but still wont fire


Check for spark
If yes, it is getting FIRE, just needs AIR and FUEL

Give it a 5-second shot or two of Starting Fluid (Ether) through the Air intake (filter) and try to start

Does it kick and run really fast and then stop?

If not, pull the plug, clean and check for GAP of 2-3 matchbook covers. Retry. Does it run (or try to)?

If it does, Now we have to look at Clogged air or fuel filter or water in line(s)

Remove air filter. Try ether again. If it starts and runs, replace or clean air filter. Done!

If not... Replace AIR filter and Drain fuel into metal or Glass jug, take off fuel filter, open and drain fuel bowl. Replace fuel filter, refill tank, prime, give it a shot of ether and try again. If it runs, Done!

If it still will not stay running, but you can coax it by giving it a blast every 5-10sec, it could be linkage, stuck choke, throttle plate or jets. Give carb a good cleaning, check throttle plate (in carb throat between it and Air Cleaner) and.check Choke. Try again.

If it still will not run, take to mower mechanic.

the floats in the carb are stuck. you can try lightly tapping on the carb with a screwdriver that should do the trick.
