Guys & Gals I am a complete novice here. I inherited an old homelite Super Mini that use to be my Dad's some 30 years ago. I remember chopping down dead falls to get into some high lakes where the fish were bigger than the stories! I completely cleaned it up, put in a new carb kit and got it running with the exhaust port and air filter off. When I get it to about the half trigger stage it dies and I can see gas coming from under the carb. I assume this is not correct. I can keep the saw running indefinitely at medium to high speed and the gas dries up. As soon as I reduce the throttle, gas starts coming from the bottom and it sputters to a stop. Keeping in mind I don't know how to tune this thing, can I get some help from some of you? How to I start. I have heard I need to turn the low and high speed settings clockwise very carefully until they can go no more then back them off 2 turns to start. Is this right? Is a turn 180 degrees or 360 degrees? Appreciate any help you can offer.

What you described might very well be your problem.One full turn is 360 degrees.You only want to start the saw out at one full turn out after seating.You might have it set way too rich which is causing the saw's carb to flood.You may have to go as lean as 3/4 turn out or you may have to increase it to 1 1/4 turns out.

Thanks Ed. Turns out I was only out 1 turn. I will try a few settings tomorrow. But I may have to take the carburetor back off and check everything. Can you tell me if it is normal for the carburetor to leak a thimbleful of gas every time they stop? Also, can you tell me if the hole in the picture below should be there? To me it seems like it should not. Gas leaks out of this hole pretty close to the exhaust. The hole is just below the right carburetor screw. Thanks.  |

The hole is there by design.
There should be a cotter pin in the hole with a felt washer under the head of the pin.

Collin,your carb shouldn't leak any fuel at all.I agree you'll have to pull the carb again (each successive time gets a little easier).I think it's possible that your metering lever might be set a tad too high.It's been a while since I've had an HDC apart.I think I have one to pull from an SEZ to rebuild.These carbs have a very common issue - the check valves in them go bad over time.I don't think it's time to pursue that avenue yet though.Let's just go with the metering lever height first.

Thanks Tim and Ed for taking the time to reply. I found the felt and cotter pin in a bag of parts that came with the saw. Put it back in the hole. Not sure what it does however? Ed I took the carb apart and you were right on the metering lever was to high, it was above the top of the body of the carb. Took a few tries to get it right I hope. I did look at the check valve as I hope I don't have to pull it off again. My hat goes off to you guys who work with these little parts, getting the new snap ring on was an act in frustration. The first time I went right through the screen and had to get another. I think you need meditation working with these things. I will give it a try in the next few days and let you guys know how it goes.

The felt and cotter pin help close off the weep hole . The hole is there for drainage of regurgitated or leaked fuel/oil. It just drips out and is vaporized on the cylinder. Some dampness is very common in the air box. Sounds like you are finding a solution to the problems. Lots of great help by the members here for any troubles!.
One thing I have found with the Mini/EZ/ XL1 saws is: It is good to put on your watchmakers suit before working on them! They are small, confined and difficult to service and repair. Patience and careful attention to details nets better results.

I've now stopped the fuel from leaking from the carb. The saw start within 3 pulls of the cable while in prime position and continues to run as long as I have a little throttle. But as soon as I release the throttle it dies. What is the basic setting for the throttle screw? How many turns? The low speed idle and high speed idle are at the default 1 turn. Thanks for the help.

You'll see a 3rd screw just below the hi & lo.Turn that screw in 1 full turn to start & see if that makes a difference.It might need more adjusting than that.
