What's on your bench today?

[Richard Thompson]

A 242 xpg that's got me totally foxed. Starts and runs for a few seconds then dies. Tank breather changed. Fuel line and bobbin changed. Impulse circuit checked. Needles checked. Carb diaphragm checked. All ok.

 

Run out of ideas but something is causing it to die.

 

Ideas?

 

Check the fuel lines for a split or a pinched spot I had an ms 250 that would happily sit and idle all day, as soon as you give it some revs it would die turned out to be a kinked fuel line under the carb

Fuel line definitely not pinched. Checked that on reinstall. Have to say it's got me puzzled.

Another thing that puzzled me today was this: I went to my local husky dealer to pick up some parts. Asked for a quote on a p/c kit. They wanted £375 for the kit...

 

Same kit retails in the states for $199 )about £135... Go figure.

 

Anyone bought parts from the states?

Best get them shipped duty paid as the royal mail sting you for tax plus £10 and often add £££ to your purchase.

Any thoughts on the 242 issue spud? I'm stumped!

[adw]

Incorrect fitment of the induction block gaskets, covering impulse, dirt in the carb main jet?

crank seals leaking? no good checking the fuel pick up filter, replace it.

What happens if you turn the idle up, does it continue to run? If you rev its knackers off when it starts, does it rev out? Have you tried turning out the L screw another 1/2 turn and giving it more idle speed to get it going.

 

After all that is said, the 242 is an old machine and would benefit from pressure/vac checks and a new carb kit but the above is where I would be if I had a starter that died.

 

Have you taken the muffler off to check the piston and done a compression check? both should be done as I have had a number of machines in lately with toasted pistons but good compression.

Hi Dan I have used ptfe tape on a spark plug before and it worked long enough till I could tap and helicoil a new plug thread ( two weeks wait on the post till the helicoil kit turned up ) and the tape seemed fine if a little charred, but for a permanent repair I'd use high temp liquid gasket or gun gum exhaust compound

 

Thanks Richard.

 

I have red Dirko gasket compound. That's supposed to be high temp, would I be better off using that rather than the PTFE tape? I didn't think of using that and I'm not sure it's suitable for threads.

 

I just don't want to send the saw back with something that isn't a permanent repair.

Muff has been off a piston is in nice nick. It's had a carb kit but I may re strip and and u/s clean to double check. I'll have a bash at turning the idle up. Revved it's knackers off yesterday after starting. Didn't Rev out just died like it ran out of fuel.

 

Will try the adjustments and see what happens.

 

Not letting this one win!

 

Thanks all for suggestions.
