Old wards 34 cc chain saw problems

[reddog349]

I was given a old 34 cc wards chainsaw and im trying to get it running .First let me say im not a very mechanical person.<br />After getting the saw I cleaned the plugs put in new fuel and got it running .It runs wide open but when you let it get close to a idle it dies.<br /> It cuts well but dies when I let off the throttle.I turned the idle up but that doesnt help.It does have a screw with the word lo beside it-not sure on that.Any ideas or sugestions?<br />What is the proper fuel mix?I was told 1-25.

can't help you much here, almost always, the carb on a 2 cycle engine will be gumbed up if it is not used regularly. the only thing to do is either rebuild the carb, cleaning out all the fine passage ways, or replace it with a new one..The new one is probably not an option, so I would try taking the old one apart and soaking it in cleaning fluid (available at a parts store) and then blowing compressed air in all the passages. put it back together, adjust the idle and speed screws about 2 turns open and go from there...good luck

The Lo is for the idle jet speed turn it out a 1/4 turn to see if it idles. If it does then you want to turn it to go as fast at idle as you can then turn it out 1/4 turn.<br /><br />Where I live at 5000 ft you can adjust it to idle smooth then when trying to cut at 7-8000ft you need to adjust Lo and Hi speed all over again.

"Lo" is the low speed mixture screw. You can't hurt anything by giving it some turns. You tune it quite simply by turning the screw one direction or the other until you find the sweet spot where it's idling OK. Then turn it in until it starts to stumble...then turn it out until it starts to stumble. Then set the screw dead center between the stumbling points. That sets your low speed mixture.<br /><br />If you can't adjust it so it idles with the low mixture and/or idle speed screw, then I agree is is likely necessary to disassemble and clean the carb. Chainsaws that are rarely used are prime candidates for having gummed up carbs. 25:1 mix is certainly a safe mixture that won't hurt a thing. You could probably get by going as lean as 40:1 without any problems.

Well I got in running good although not at lower rpms. It will run great at 2/3 to full throttle.The problem now is the fuel actually got hot enough that it boiled after cutting for a few minutes..Im guessing Ive ruined the motor although it still runs.

Remove the carb and see if it has any writing on it. Chances are it will say tillotson and give a number. Call a small engine repair place and order a carb kit for it. Cost is about 10 dollars and are real simple to do.
