FOUND IT Tillotson 296a

[Josh0619]

Looking for a carb for a 390xp, would like to stick with a Tillotson as I just bought a carb kit for mine but the low speed passage is plugged. Tia

I'm not familiar with that particular carb but can't you just remove the Welch plug and clean the passage?

Those carbs are kinda hard to find. Might be worth running it through an ultrasonic cleaner to see if you can get it cleaned out.

but the low speed passage is plugged

As stated above, I would either try the ultrasonic cleaner or popping the Welch plug and cleaning it that way (hopefully your carb kit came with a replacement Welch plug).

If you need the saw up and running in the mean time until you get your carb working, here is a potential AM carb that may get you by:

You may have already done this. Blow it out with carb cleaner from where the fuel enters the passage under the metering diaphragm? Should be able to see it come out inside the venturi. Also, some carbs supplement low idle through the high speed jet. Welders tip cleaning kits are great for cleaning those tiny passages as well.

I have a brand new 295 but I’m not sure they interchange.

I’ve pulled the Welch plug and can not get anything to fit in that tiny hole. Short of an ultrasonic bath I’ve tried everything and it will not open up.
