Echo 265 not revving

[Shane]

I have two Echo 265 long trimmers.

One runs perfectly, but the other....

Starts easily, will tick over all day but doesnt want to rev up.

When you squeeze the throttle it splutters then cuts out.

It will start fine when cold, and re-start perfectly when hot.

 

So far I've

checked the compression (150 psi)

Made sure the throttle cable is opening the carb

Tried it without the air filter

Removed the exhaust and the pot and piston don't look scored.

I've checked the fuel intake line for leaks (none found)

The breather seems Ok - I tried running it with the fuel cap loosened.

I've taken the carb off, removed the cap over the hi adjuster and removed/cleaned the hi jet (no crud visible).

I've tried adjusting the hi adjusted but no joy.

I took the carb apart and all diaphrams seem OK.

I even disconnected the cutter in case it was offering resistance.

 

I just can't get the bugger to rev up - -aaargh

 

Any suggestions what else to check?

Sounds like a high jet blockage initially,maybe the carb needs a strip and full clean.
