NU50 Carb oil injection

Timothy Hunter /

So I got a NU50 with no carb/air box. Ordered a carb off eBay, and it lacks a oil port. Can I just drill and tap a barn on the engine side of the carb and plumb it in? Or dose the oil need to go though some orifice.

Run an oil line to the port at base of intake

I actually did that after I posted it. I realized I had a vacuum cap on their from when the auto choke was removed. I had to get a longer oil line. It's 3/32 I'd 3/16 od. It fits perfectly inside the barb with a bit of lube. She seems to running good now. A little smokey, but it had about 1/8 tank of premix left and I just dumped fuel on top of that. The oil sensor even works, the PO has just put a zip tie under the float to keep the light off.
