61 new barrel slow to pick up

[Rayburn]

Hi folks, long time reader but joined yesterday.

 

Got a minor problem that someone might advise on.

 

Husqy 61 about 25 years old, been going strong without problem until recently.

 

One of the muffler threads in the barrel had become worn/expired and although i did think about re tapping it. I decided to buy a replacment barrel. The meteor one.

 

Anyhow, i put the barrel on, now have a problem with it not picking up fast enough.

 

Starts ok, ticks over for a time runs at full ok, but is just very sluggish to pick up. So i dont want to run it until its sorted just incase its lean and causes damage.

New spark, new fuel filter, new air filter, new muffler.

Running on aspen.

I know its probably the carb needs tuning, but would it be THAT different for a new barrel? I wouldnt have thought so.

Over to the pros.

Slow to pick up sounds like its running lean, gaskets between the induction block round the right way? try richening up the H screw ( counter clockwise) on the carb

Is the saw easy to turn over with the plug removed? Has the carb been set to one turn on the H&L screws? Has the carb been overhauled? Is the muffler free of blockage - had one once with a plug of mud rammed in the exhaust outlet!

 

Check the fuel filter and the fuel line as well!

Thanks for the replies

 

To be honest I haven't done any checks yet, just got it back together and was sidetracked.

Just double checking there is nothing obviously stupid that I have done or not done.

 

I've got a carb rebuild kit here somewhere, might as well have that apart as well and give it a good clean.

Everything else is new.

 

Be good to get it running again as the 440 is ok but sometimes need something a bit more oohmphy

The 3120 is just well.... BIG!
