Hi Guys, a bit of an update I managed to source a WT-774 carb in UK via good old eBay. I'd still like to replace the Valve check 0008004, and retainer, check valve 0009008 on the Zama carb. Has anyone removed the Welch plug before on these carbs..having trouble finding these parts too. How do you deal the Welch plug? It's oblong shaped.
Well looks I am running late on this one.
Don't the retainer as it is NLA. As for welch they just a thin piece of aluminum and a sharpen pin punch will remove it. Just be careful not the damage the under laying surface.I actually got a set install punches for installation those bango welch plugs along with the triangle shape ones.
