Super EZ starts then stalls

[gerryw]

I am the original owner of this wonderful little saw #32390930. It had started and run great for many years. It had sat
for many (15-20) years with only occasional use. A few years ago I tried to start it and it would only run with air filter off.
Purchased new filter and found that the saw wash hard to start.
this is what I have done (about 2 years ago):
                                                                      - replaced fuel filter
                                                                      - installed new fuel line from filter to carburetor
                                                                      - purchased & installed carburetor rebuild kit
                                                                    ( carburetor cover says " HOMELITE"
                                                                                                         "TEXTRON"
                                                                                                   PORT CHESTER, NY
                                                                        #3-21-109  )
                                                                     - backed out hi & lo needles 1 full turn from seat
   When attempting to start at that time, engine would run for about 3-5 seconds and stall. I gave up and put the saw away
after cleaning all fuel out. 
I have retired from upstate NY and located to the central Florida area. With impending hurricane looming my interest in the saw has peeked. That has led me to this handy site. Today I mixed fresh fuel and oil and cleaned out pin holes in gas tank cap.
                                                  -switch on
                                                  - compression trigger engaged
                                                  - choke pulled out
            Took about five pulls and the saw popped. Pushed choke in and next pull the saw started and was running. My thought
    was : "wow must have been that gas cap? After about a minuet of idling the saw stalled.  Now back to the same thing. Starts and runs for a few seconds then stalls.                 Be nice if I could get this nice machine running as in the good old days.

                                          Thanks for any input you may have,   Gerry

Does it "stall" like it's running out of fuel or shut down from loss of spark? Could easily be one or the other. I know if points and condensers are wacky they can cause interesting problems. My super ez needs points badly as at random times it will not want to idle as well and I've narrowed it down to points or condenser.

I'd file the points. It may just need the idle turned up a little. Turn it up and start it. The chain will be turning allow it to run for a minute to allow it to warm up then back it off until the chain stops. At it's age seals are also due.

I went back at it today. Spark plug was wet, so I took it out and pulled several times (switch off). Plug back in, choke half out, and switch on.
one pull and saw started and died. Noticed a very small amount of fuel inside the chamber where carburetor and choke linkage is.
Could be dripping from carburetor throat opening? Removed spark plug ( it was wet ) and pulled again several times ( choke not on ).
Plug back in, switch on, no choke. Just before 1st pull I decided to turn hi and low needles in a quarter turn. Saw started and continued to run !
Ran it for a good 10 minuets and shut it off. It started right back up and continues to run. I just have to make final idle adjustments.

Thank you all for your attention, Gerry

Long story short. I still have a starting problem.

Saw will start with choke out and decompression switch on. It will immediately stall if decompression/trigger is let go

right away. If I "feather the trigger ( compression switch still engaged) I can keep the saw running longer (15-20 sec) and

can disengage decompression/trigger. It will continue to run and sometimes I can stop feathering the trigger and almost have a good idle.

But no matter what, it will always die.

This is what I have done : Cleaned out gas tank

New filter and fuel line

Carb rebuild kit

Metering tab is just slightly above straight edge placed on top of carb body with gasket in place(as described

in service manual)

Hi Low needles adjusted as noted in service manual

This is a nice old saw, visually in very good shape and ran flawlessly for many years. Was put away for many years.

I'm retired now and to tell the truth, really don't need it any more, but would feel good just to have it purring again as in

previous years.

Thank you for reading my posts and offering your learned suggestions

Hi Gerry,

A couple places to go from here...

• The carburetor check valve, located under the metering circuit plate, could be bad nad it will cause the kind of symptoms you are experiencing. From the top it just looks like a screen with a circ-clip, but there is a piece of diaphragm material underneath that acts as a check valve. www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=homelite+93910&_sacat=0&LH_TitleDesc=0&_osacat=0&_odkw=homelite+330+coil
• There could be a broken reed valve...no real good way to inspect without removal.
• Have you checked the compression? Anything lower than 120 is going to start having idle and performance problems.

I'd put my money on the check valve based on what you have described. I've had a number of issues with the Walbro HDC carbs that turned out to be the check valve.

Thank you so much for your suggestion. I will get right on that and eventually let you know results.

Regarding my check valve kit.
Kit came with brass bushing with screen attached, a Welch Plug ? I think it's called, and a thin rubber disk.
When I removed the old screen/bushing, their was no rubber disk present underneath. I assume their should be?
Please advise
thanks so much, Gerry

also, I guess the plug isn't used as I see nowhere it needs to go.
