Homelite CSP3314

[JPR123]

Hey all,

 

I have a cheapo Homelite CSP3314 that I have had since new for little garden jobs. Has not been used much and not for a few years at least. Am pretty practical so I would like to get it running as I don't like waste and simply getting rid of stuff that can be fixed and used / passed on to someone who may use it.

 

Long story short it wouldn't start so I have replaced the plug, fuel lines, fuel filter, purge bulb, air filter and the carb gaskets. Fresh fuel in it and it will start on full choke with the throttle locked on. As soon as you you push the throttle in half way it dies. within half a second. If i push the choke in very slightly and let a little more air in it will rev. I have not played with the carb adjustments as want it at lease running first before tweeking those.

 

Any thoughts on likely problems / what to try next?

 

As I said, I don't need to use it so more of a bit of fun to see if i can get it running properly.

 

Thanks all

have been thinking.

 

In my limited knowledge / experience world there are probably 2 possibilities.

 

1) A lack of fuel getting through. Means with the choke open it is too lean hence stalling. Solution probably a full carb disassembly / clean. How can i test the fuel lines / filter? suck on the fuel line and see what resistance there is? if i do this what should i be expecting? Hoping it isn't that as i replaces lines and filters.

 

2) Ingress of air from somewhere other than where it should be - again causing it to run lean with throttle open.

 

3) I have not messed  / tweaked the carb settings but could it be these?

 

How would i work out whether it is 1 or 2 or 3 above?

I don't want to bin the saw but fundamentally it isn't really worth spending money on (bits so far were £14) if I don't need it/ would give it away after.

Sounds like lack of fuel, check the gauze strainer on the pump diaphragm side of the carb. Do take it out to inspect as they can get blocked by a fine scum. If that is OK, try giving the H&L screws 1/2 a turn anticlockwise and that should get the thing running.

These saws are usually set on the lean side on manufacturing to save them failing the emissions checks and as the saw gets a bit older, it stops the things revving out.

I've just had exactly the same with a little Jonsered that had been sat on the shelf for years and which I took in to one particular (once a week) job with a view to leaving it there for whenever it was needed. When I tried to start it I had exactly the same as you with the choke on choke off rev rev and die. Start again throttle choke choke throttle die.

So I left it, got on with something else, and had another go the week after.

T'was a bit better: could rev the absolute nuts off it the second week for as long as I could bear to but it still died. 

So I left it, got on with something else, and had another go the week after.

Third week it started and ran fine, just as if there had never been anything wrong with it: sharpened the chain, and it ran and cut like a new saw.

It was all just as if it had to learn what to do again after being left on the shelf again or maybe that the diaphragm just needed a good soak in petrol to re flexibilize it.

Or something.

And by none of which do I mean to distract from what people with far more knowledge than I'll ever have ^ have said; just that these things happened.

Best of luck
