Question about Dual Milwaukee 6950-20 12" Bevel Compound Miter Saw

1 Answer

The rpm of the motor seems to flutter and run uneven making a cut or not. If it were a carb, I'd say it was getting dirty fuel.

What year make model and engine size do you have??

Aside of the pressure regulator that may be bad, you may have an injector that is leaky, or one of the O-rings on the fuel rail , most vehicles that I test will hold pressure over night into the next day without losing any measurable pressure
if you relieve the pressure and then cycle the pump the full pressure should be reached in no more than 1 second, longer than that, or if it takes a few seconds you may need a fuel filter, when the vehicle sits and the pressure lowers between the pump and the regulator, as soon as you go to start the engine the injectors open and the pressure drops momentarily near to nothing and the pump takes several seconds to push the fuel back through the filter, this takes a few seconds all the while the injectors are still opening, so the engine takes longer to start up..
Note: if the engine is running a bit to warm, when you turn off your engine the heat causes the cool, no longer circulating fuel to heat up and expand forcing the fuel back to the tank, (vapor lock) this is only momentary because of the way the pump circulates the fuel back to the tank, but it causes the engine to take longer to start.
the currant to the injectors can only be tested with an AC meter because the voltage though DC current, is a pulsating DC, it pulses each time the ECM tells it to open, if they all were powered just turning the key on they would over heat and burn up in just a few seconds,
some cars have grounded injector harnesses that the computer sends positive current to the injectors through one wire while the other is simply grounded, others have positive current applied at all times and the computer grounds the other wire momentarily in order to operate the injector, so each wire has to be tested both ways, one to check the resistance to ground and the other to test positive voltage.
the most common reasons for the loss of injector errors are
1, a shorted injector, (this caused all the other injectors to stop working or work very inefficiently)
2, the cam sensor (the ECM uses this as a reference in timing the injectors in conjunction with the ICM)
3, the lack of fuel pressure to them (all the many things that can cause this condition)
4, a bad ignition control module ( the computer uses the signals from ICM for a reference to time the injectors as it monitors and changes the ignition timing)
5, a bad crankshaft position sensor ( the ICM is using this to set the ignition timing and to send the reference signal to the ECM)

Pontoon w/25 horse merc out today and suddenly the motor seemed to be inconsistenly getting fuel never completely lost power, the fuel line is dirty or something w/ filter. ?

Hey Marg, Why do you think its fuel related... there could be several issues that could cause this issue.
If you think its fuel related.. make sure the bulb pumps tight(firm).. You can replace the fuel filter if you feel its the culprit (won't hurt!)..
Has the engine been setting up for a length of time? If it has, the problem is probably carb (dirty and stopped up jets) related. When carbs set up, and the stuff now called gasoline evaporates, it leaves deposits -carb clogging deposits! If so.. take the engine to a competent mechanic and have them cleaned and set.. that should clear up the issue!!
If this is not the case... take it to a professional mechanic and let them diagnose the issue.(its cheaper in the long run!!)

My outboard motor doesn't idle at low rpm's, it cuts off when put into gear.

Could be several reasons for this, poor quality / dirty gas, restricted fuel line either partially blocked or pinched at some point come straight to my mind.

fuel pump sounds to be problem, though I'd replace air cleaner first to rule it out cheaper than pump (pump may have internal filters that are blocked)

Not enough information, but there are two things I didn't read about you checking. Make sure the fuel quick connection on the engine (and possibly the fuel tank) is locked all the way in first, Then see if your fuel pump is working. Disconnect the fuel line from the carb and, holding it in a gas can, have someone turn on the ignition. If It's an electric pump, it should start running fuel, if mechanical, they'll have to crank it a little to get fuel going. If you get plenty of fuel that way, your float in the carb could have gotten stuck, or something in the line got into it.

Make sure you are using fresh fuel mix (50:1 ratio). Don't use boat motor oil in a saw--only modern synthetics made for saws. Always premix the oil and fuel thoroughly before adding to the saw. Check the fuel filter for plugging and the condition of all fuel lines, plus the primer bulb condition. Check all carburetor fasteners for tightness. Make sure the air filter and muffler are not plugged. If still no help, you may need to service the carburetor. For an excellent article on Walbro carburetors, go to: Pay particular attention to the placement of the lower diaphragm and the cover gasket--interchanging positions of them cause many headaches. Adjustment of the two jet screws require a special 'D' screwdriver which may necessitate a trip to a servicing dealer for adjustment. Hope this helps!

Are you sure it has a good plug and spark? If not you might have bent the float when you cleaned the carb, try spraying starting fluid in the intake and crank the motor, if it fires the problem is fuel, one of the Jets in the carb might be clogged also make sure you have no water in your gas.

Starts and idles and runs half speed ok -- dies off on full throttle fuel lines & filter ok has ffuel in tank good spark & new plug muffler & screen & ports open clean good compression

Since you don't indicate the make and model, I can't give you specifics, but when I had this problem it turned out to be a dirty carb. This can cause uneven fuel flow and loss of power. At full throttle, you may not be getting sufficient fuel to work properly. Try cleaning the carb a nd update this with the results.

Did you change your fuel? If you are trying to use the same fuel from last year without being stabilized then that would cause your problem. I know that you already had your carbs cleaned but it sounds like something els got plugged up in them. If you have fresh fuel then I would take the carbs back apart and check your jets in the carb to ensure that there is nothing obstructing any of the orifaces in the jets. I am a boat mechanic and I have had to take carbs apart 2-3 times sometimes if they were varnished really bad to make sure I got all of the gunk out.

Makita G11oo portable generator. starts on choke. cuts off run

Just noticed your question... If you still need a little help:
1. If the gas is from last year, drain the tank and the carb bowl and replace gas with new. Visually inspect the inside of the tank sure there's no sediment that needs to be cleaned out.
2. remove air cleaner and make sure it's not plugged or dirty
3. plug the spark plug and clean with spray carb cleaner.
4. At end of season, mix some gas stablizer in with the fuel to keep it from going bad while in storage.

Let me know how it goes..
