could it be the crab

[donthraen]

I have a jonsered 450 today it was going real good then out of the blue it acted like it ran out of fuel and shuts off but will start rite up again for a short time but if I let it cool it runs longer the cooler it gets the longer it runs till it gets hot again it gets irritating and makes the job longer could it knead a carb job what do you think it does have new lines

I never heard of a crab job, that sounds kinda personal... possibly a carb job. LOL I would check the easy stuff first, like the fuel lines, tank vent and impulse.

Crabs are bad! Carbs are good!

It could also be your coil or other ignition fault. When it's all heated up and then won't run, pull the plug and check for spark. No spark and you've likely got an ignition problem, with the coil the likely suspect. Spark and you've likely got a fuel delivery problem.

Crabs taste good as long as they are from the sea!

 

[Arrowhead]

I don't think its a carb issue, ignition failures are common with heat.

Unless you catch them from a mermaid.

Judging by all the mermaids I have seen I would sure take that chance.

Those crabs are nasty tempered critters at best of times.
I bet he's overheating under there and has found a remedy.
Its possible he's learn't to pinch the fuel line with those pincers of his and starve the engine of fuel. :hmm3grin2orange:

Crab lice don't care about outside temps. They are geared for a different environment.

As I and others have said, look to testing the spark. You'll be glad you did, because it'll tell you whether you have an ignition or a fuel problem (I'm betting ignition).

Place the saw next to a pile of wet sand overnight, that should do the trick.

going to try that in the morning but i did notes the gas tank gets lots UV pressure in it wen i open the cap its like shaking up a beer and opening it sprays everywhere but will check ignition first like i said didn't think of that till you said it thanks

Sounds like you have an issue with the gas tank vent. One more thing to check.

looks like i gotta check everything

If your tank is building that much pressure, it is definitely the tank vent! Start there, as that is not right for sure!
