Adding Purge Barb to Carb

[GTSAW]

I'd like to add a purge barb to a Chinese knockoff of a WT657 to allow the use of the purge bulb on my muffler moded Craftsman 358.351181 saw. The carb has a spot where such a barb would go, shouldn't be that difficult if the metering side has the provision for the intersecting hole. Haven't opened the carb to check for possible drilling, just wondering if someone has done this already. Don't like pulling the thing forever to prime the carb, know this is totally unnecessary but it's a challenge I want to take. Thank you

I know this is totally unnecessary but it's a challenge I want to take.

If you do end up going this route, take pictures and share, I am sure there are many here who would like to see the process and possibly attempt it themselves too!

You’ll have to see if the idle circuit if the carburetor has a check valve. If it does, then you’re good to go. If it doesn’t, the purge bulb will suck air through the idle passages. You may be able to retrofit another WT carb from a saw with a purge bulb; some old poulans had them, and the Echo 370/400s as well.
