I apologize I posted this in two different places. The 33cc page doesn't look like it gets a lot of traffic. My dad has a homelight 33cc I replaced the fuel lines cause had fuel in primer bulb area and assumed this was the cause of it not starting. So now when I pull start it fuel just drips from underneath and from around exaust. The vent for tank seems to venting properly it also has excessive fuel on spark plug and the carb but does have a strong spark.Hopefully someone can give me some ideas how to diagnose. I am fully capable of rebuilding automotive engines but small engine repair is not my strong suit. Any advice would be greatly appreciated

It could be several different things. Also need to know which model saw you are working on. If it is one of the newer vertical piston saws, it could be low compression. I recently worked on a Z3300 saw that gave me fits and could never get it to run correctly. that one had just barely enough compression to start but would not continue to run / rev.

OK I was researching on YouTube Homelite 33cc this time I researched Ranger and found some good info. I took carb apart and cleaned needle and seat and no excess fuel when it started the rpms went ramped so I shut it off. Let it set now it wants to start everytime when choke is full 3 pulls and half choke it fires runs for a millisecond and dies tries to fire the after then nothing it will do that everytime you do the start procedure. Don't know if idle on carb has ever been properly set. What is your guys recommendations on where to start on the 2 adjustments on the carb or is there further diagnostics I can do? Thhanks

The initial settings that i use for the Hi / Lo screws after a rebuild are 1 1/4 turns out from full seat. That will usually get them running. From there less than a half turn each in either direction to get it to run properly. But your saw may be different, there might be limiting caps on the carb needles preventing adjustment. I usually prefer to work on the older saws.

OK I will start with that. I believe the needle and seat were the issue cause in the needle hole was quite a bit of dirt and on the other side of carb the screen was almost plugged. Just off too of your head anything else I should address if doing the adjustments do not keep it running? I doubt the plug was gapped when installed can't find a gap setting for this 33cc. Are the plugs gapped according to plug number or do they always need gapped. I am getting a strong spark with easy pull of string so probably good do you think?

So turned them all the way in and 1 1/4 out it starts on full choke but dies when switched to half then pull 3 to 5 times on half choke starts revs up and dies. I tried leaving full choke on see if it would continue to run but it dies seconds in. I did notice when priming the bulb you can feel the bulb build pressure soon as it dies no pressure at bulb. I do have a little fuel leak at the prime bulb the fuel lines fit the filter and fuel inlet on carb nice and snug but not as snug on the prime bulb and the return tube on carb. Wonder if that's causing enough fuel lose to keep it frome running.

I wanted to upload a photo of my fuel lines to make sure I put them on correctly cause if I prime then pull it starts and dies immediately every time but I don't see a way to upload am I missing it or not available?

From the primer bulb, The short nipple goes to carb. The long nipple goes to the fuel tank. |

OK I have 2 hoses off the carb 1 with a long thick nipple and the other is a smaller curved nipple so from the short nipple on the bulb does it go to the small nipple on carb and the bigger nipple goes to fuel tank with filter on the end is that correct? |

There"should"be two lines coming out of fuel tank. The one line, with the fuel filter goes to the bottom of carb. The other line goes to a long nipple on the primer bulb, should go into the fuel tank. The short nipple on the primer bulb, should go to the top of carb. I'll see if I have a IPL or find one for you. |

bobby167 & bamaboilermaker Tuank you both for the assistance to get this chainsaw up and running. bobby167 im assuming they have different carbs they used on this saw. When I researched it seemed like everytime I watched video everything looked identical to this one until they remove the carburetor. This one has the fuel in nipple on top rear corner and the return is borrom front corner. I did have the hoses revered at the bulb cause when I pumped it would build so much pressure bulb would get stiff. Now it fires first pull on full choke and I follow starting sequence everytime and she starts and runs without issues for the first time ever even new it never stated like it does now! 👍 I do have a couple minor questions. It was slinging chain oil excessively from the chain I cleaned everything to the point of looking new if it continues what do I look for? Last thing I have a new tank fuel line filter for weedeater will that work ok on this saw? Didn't know if there was a difference in flow between them. Again thank you guess for the help I really appreciate it. bobby167 I apologize for the double message I sent from here! Still learning this forum a bit different compared to my Auto and Tractor forums I use. Have a great Holliday and I hope all of you memories are great and bring a smile to your face and some piece to your heart!!!

Don't think I have ever been this aggravated! Rained hard last night been waiting to get saw going so I can finish clean up around pond. Had big tree that the 40V chainsaw can't handle! Finally dry enough to drive out and get this tree out of there. Homelite won't even make a sputter now! Gerrrrrr it started 5 or 6 times last night with no issue! Wot with it tonight hope it behaves or it's going to the scrap yard!

Sorry Homelite it was user error! I had adjusted high idle speed down a bit last time I started it. I turned it up half turn and fired right up got it set perfect now no more tinkering with idle speeds! 👍
