Starting issue

I Know Something · Jan 18, 2019

I got my craftsmen saw out to my garage finally. Got it to do more then just idle. Working on adjusting the carb. Then. Ran it out if gas. No problem. Filled it up. Then. The issue hit. It's the first time I've had to have my daughter hold the throttle wide open and I pulled and pulled and pulled till it started. Eventually. I'm assuming that this is not normal and I have something going on. Any thoughts you may have are welcome. Mine? Time for a new fuel filter? I just replaced the fuel lines.

Carb kit. Or some carb settings way off.

What kind of Craftsman?

35098 craftsman 50cc. I just did a carb rebuild. It runs great. Just the restart after running out of fuel is a new issue. Or, just keep an eye on it and dont run out?

Or it needs more compression. It's a guess. I have no idea if there is a popup piston made for these or not. I cant find one yet.

I know you had just refueled, but did it smell like fuel? Flooded?
If you ran it out of gas, it shouldn't have been flooded unless some worked its way through the carb while filling.
I know my 028 is a pig to start if I run it dry. But if I kill it at the first sign of starvation, it fires right back up.

I was testing it on some 8 inch rounds of oak I have for firewood. And it ran out going threw one. Checked the muffled and it was dry. Flooding was my first guess. Filled it up. And the festivities began.

Sometimea a carb kit doesnt fix an issue and you just have to replace a carb. Not saying this s your problem, but i went reound and round on a chinese low hour saw i had. Saw stopped running, carb issue, i rebuilt it, was better but not right. I messed with it and messed with it. With a suggestion i bought a new china carb off ebay and it worked fine!

I'll definitely keep that in mind. Thank you.

I remember this saw now. I was messing with one like this for a coworker and I thought I had the carb set right the first time. Then after the second time of messing with it i got it right.

I was wanting to go to the woods and make a video of it running today and cut some cookies. Darn winter storm going threw Southern Minnesota right now killed that idea. Over 6 inches in the last 5 hours and still going strong.

I'll go out latter and check the carb again.

Try richening up the low by 1/8-1/4 turn.

When you ran it out of fuel, the fuel line and carburetor were dry.
So it needed a number of pulls for the engine vacuum to cause the fuel to be pulled through everything again.
Assuming no other issues, like the low speed carb setting as mentioned above, keeping the choke on would be the best thing to help pull the fuel in.
Just have to be careful and try not to flood the saw while doing this.
If the saw is still warm,
it could go from not firing,
to a blubbered sputter,
to flooded,
over the span of just two or three pulls

Sorry to be that guy, but did you try a new spark plug? It’s my first rule when saws do weird crap. If it doesn’t help, you can save the new one and put the cruddy old one back in. It also gives you an opportunity to see if the old plug looks wet when it won’t start.

I replaced $200 in parts on a Honda GX engine and spent 2 days redoing every part of it and it was the $2 spark plug.

After saw fully cooled down overnight, will it start again?

What’s the piston look like? If it scored, it may start cold but not warmed up.

Remember: spark/fuel/compression

I also had a saw that I could not get to run just right. Had weird idle and flutter all over WOT. Sometimes just would not start or run. I usually never check plugs cause they rarely go bad and every time I checked one in past it was fine. Well someone gave me this advice, I was like I haven't checked this one yet but it won't hurt to pull it. I found that the plug insulated had pulled loose from the metal he part. So it was blowing compression out the middle of the plug as the enter moved around . New plug fixed all the weird issues I was having.
