Sticking throttle on Mac 3200 series

[gypsydavey]

I have a Mac 3200 series saw that I use for clean-up and firewood harvesting. The throttle trigger has recently started to stick wide open and requires a "double tap" to disengage it. Is this endemic to this model and can something be done about it without taking the unit completely apart? The nearest professional repair location is miles away. Thanks in advance.

Are you sure it's the trigger and not the linkage that is sticking?

I had a 3200 and recently sold it. Never had this problem. If I recall correctly you can remove the screws that hold the top cover in place and it will lift off. Then you can pretty easily see and remove the sponge air filter and you should be able to see the linkage coming from the trigger to the carb. Then you can squeeze the trigger and see if the linkage is binding up anywhere at full throttle.

You might need a shot of WD 40 somewhere, or it could be as simple as straightening the linkage somewhere if it is bent.

It should not take much to correct the problem either way unless it is due to wear, in which case you might be hard pressed to find a replacement part. But on the internet I wouldn't rule it out.

Good luck.

Anti vibe or solid handle/chassis?

The anti vibe version uses a wire sliding in a sheath that can get dirty and gum up. As above, WD-40 is your friend.

The conventional chassis has just a thick wire link. Look for binding or interfearence with the fuel lines or the on/off switch wires.

Thanks for your helpful advice. The odd thing is, the trigger never sticks when the saw is NOT running. Fire it up though and things go haywire. I'll pull the cover first.
