Pioneer 1074 Wont start

As I recall, that model has the decomp button , so the compression should feel poor when pulling the rope.
There should be a gizmo on the starter pulley that pushes open the button when pulling the rope.

Ok sounds good. Will give that a shot. Just carb cleaner? Or is it ok to use a bit of gas in a spray bottle?

Only problem with a spray bottle, is that the gas may melt the plastic and ruin your saw innards.

 

[HarleyT]

But the goal now is to totally dry your saw so you can isolate the flooding possibility and address one problem at a time.

 

[mixemlewis]

Ok. I did see the decomp thing when I replaced the cord. It looks like its working properly

 

[mixemlewis]

Will drain and dry this evening. What is a good product you'd recommend for test firing? Can you use starter fluid??

 

[dsell]

I use fuel mix. Ether doesn't have lubricant.

 

[mixemlewis]

Ok thanks

Like has been said, a common cause of flooding is an inlet valve not seating. You can clean the seat with a q-tip soaked in carb cleaner and you should have a good look at the rubber tip on the seating end of the valve. Must be in perfect condition. The spring under the valve control lever must be seated on the dimple under the lever and if the control lever has a fork in the end that touches the diaphragm, there should be a grove in the diaphragm button that the fork must be fitted into. The control lever must be free to pivot on its shaft. The diaphragm gasket goes between the diaphragm and the carb (on the fuel side of the diaphragm). Usually the end of the control lever is set flush with the surrounding bare metal rim of the carb (no gasket). As a test, after you have assembled the carb, hook a short piece of fuel line to the inlet fitting and try to blow into it. If the inlet valve is seating, you shouldn't be able to blow in, the "pop-off" pressure should be over 10psi.
No choke means Choke Off, looking in the choke end of the carb, the choke plate would be wide open.

Dried it out completely and tried to test fire the ole girl. No such luck. Checked the carb over again and slightly adjusted the inlet needle to make sure the lever was flush. Im thinking it doesnt have any spark. Any ideas?

 

[mixemlewis]

Thinkin I might have to clean up the points as I think they may have gotten overspray on them when I painted it.

 

[dsell]

Did you try my spark test?

 

[mixemlewis]

Yes I grounded out the plug and pulled the cord. No spark at all. Tried with old plug and a new one. No spark at all. It did before and now it does not.

 

[dsell]

Ok, now we're getting somewhere. Next, remove the kill switch wire from the kill switch. Try again. It's also possible the wire is bad from the switch to the coil. Also, do the same test with a different plug.

 

[mixemlewis]

Ok will do.

 

[mixemlewis]

What do the points look like? I know they are under the flywheel

 

[dsell]

 

[mixemlewis]

This is what mine looks like. Cleaned everything and also tried to spark it without the kill switch female spade connected and still nuda

 

[dsell]

In that last picture, it doesn't look like the contacts mate very well. Is that eclip suppose to be above the point box? Looks like someone lost the clip on a different set of points.

 

[dsell]

Did the condensor get squished on the end?

 

[mixemlewis]

There was 2 clips. One that you see in the pic and then that plastic cap goes on and the other clip goes on to hold it in place. Or at least that's how it was. There was a small piece of felt that went flying when I pulled er apart. Where does that go back in?
