Have an Efco MT 6500 that refuses to tick over. Will start on choke switch to half throttle but you have to be quick to catch it on power or it will just cut out.Can keep it running with the throttle only. H ave turned tick over screw right in but still will not tick over. Has had a new carb fitted and worked ok for a short time then went back to not ticking over at all. will only start and run with choke on hot or cold. Will not start when warmed up by just pulling the starter cord. This carb has limited turn on high and low jets. Saw has me beat. Any ideas.

If the saw will take full revs but not idle, and a new carb fixed the problem for a short time then I would say the issue is with the low speed section of the carb.

 

The carb has two separated systems for delivering fuel at high and low speed. Your low speed part has probably picked up some crap possibly from bad or dirty fuel. The carb needs to be stripped down, the limiter on the L screw removed and then some carb cleaner used down the L screw hole and in the metering section of the carb. It is worth looking at the jets through a magnifying glass to see if there is any debris in the hole in the middle.

 

The fact both carbs have failed suggests that your fuel or tank or fuel filter aren't up to scratch and are depositing particles in to the fuel system. An inspection of the gauze strainer will confirm this.
