chainsaw repair

I own a 16"craftsman chainsaw that will not keep running and after I cleaned it {other then the carbarator) replaced the gas,put in a new gasline and a new sparkplug I kept adjusting the three screws I got it to run but every time I tried to cut it would stall out and the bar an chain oil is just pouring out. Can someone give me a little help.

Chief63, welcome to the forum. I've look at your question but it is rather difficult to come up with suggestions not knowing if parts were replaced properly after cleaning. From reading up about those screws I got to learn that the right adjustment should be one-and-a-half turns and adjust from there. Does this make sense to you? And, if so, have you applied this?

I took it back apart again yesterday an this time I pulled the carb and found a glob of dirt in the filter in the carb itself. I thought for sure I had it but now I get it to run but when I hold it wide open to cut it bogs down and quits after about 2 or 3 seconds. I didn't know the starting point for adjusting so I will try that to. Thanks for your help.

You're welcome, my pleasure Please let me know if this helped.

i have a poulan chainsaw wood shark type Iv it will only run full speed with choke on 3/4 you see air bubbles in fuel line it will bog down & quit when air bubbles get to carb replace all fuel lines thanks for your help

Hi NASCARTOW, welcome to the forum. Sorry I hadn't seen your question before but I didn't check in here yesterday due to work overload.

Do you clean your carburetor often enough?

I'm currently trying to repair a McCulloch Mini Mac 6 that has been collecting dust in the corner of the shed for approximately 25 years. All parts appear to be serviceable except for the fuel line end that fits into the gas tank. This piece seems to be very loose-fitting and even leaks gas like crazy when you fill the tank. I can get the saw to run on its own by pouring a small bit of gas into the carb, but it won't stay running for more than a few seconds this way. The gas line is clear, the carb gaskets are in good shape (believe it or not), and I'm getting very strong spark at the plug. What can I do to get the carb to suck gas from the tank? I've spent the evening searching the net for answers, but no luck so far. Thanks in advance for any help with this problem.

crzymilkman welcome to the forum

I think the best way to handle this is to see if you can somehow obtain a fuel line that fits the saw. Isn't that a possibility?

Its a possibility if I could just find someone who has one. So far, no luck. I figured surely that I couldn't be the only one who run into this problem before. This is my first time getting a small engine to run that was previously dead. Talk about a confidence builder! Thanks for taking the time to reply to my question. If I find a solution, I'll be sure to post back here. I'll be checking back in from time to time. Thanks again!

I am sorry I couldn't be of any help here

(I still think getting the word out in the neighborhood you're looking for an old chainsaw someone wants to throw out and get the fuel line out of it would be my preferred -because easiest- "method" of trying to solve this )

Just thought I would let everyone know that I managed to fix my fuel line problem. I used a piece of car fuel hose and beveled the inside of the hose to fit the fuel line fitting. I cut it just long enough to have to use a bit of pressure to force the fitting into the hose. I got the saw running after 5 minutes of coaxing, however the carb does need fine tuning. Now if I can just get the chain to free up and flex like its supposed to, then I'll be set to use this good 'ol American saw once more. Thanks Jeffie for making me think!

You used a piece of car fuel hose? :: :: That's so creative thinking, crzymilkman! I am impressed. Had nothing to do with me though, so I really don't deserve any credits here. I think it's great you thought about that

It's about 8 years old. It runs fine for 10 minutes or so then it cuts off and won't restart until it cools off for awhile. It only cuts off when idling. So, if I'm cutting through a big log and it's "past its time" it will work OK until I let off the throttle. The problem has gradually gotten worse over the last couple of seasons. I recently replaced the ignition coil and a new plug and it made no difference. I'm pretty sure it's lack of spark because when I look down the carb throat I can see gas vapors. Could the magneto magnets be weak?

Best solution. Throw it away and buy a stihl.

Depending on your altitude, it could be vapor locking.
