I'm doing a Ryobi conversion with C&H on a 4*120.

I have a bad case of CRS, and I can't remember which nipple to put my clunk line on.

One nipple comes straight out of the carb--near the needles. The other nipple comes out the other side and it makes a 90* (degree) turn.

I think the nipple that turns 90* is the one that had the primer bulb. But, I can't remember.

I think the straight nipple next to the needles is the one that came straight from tha tank.

I'm not using a primer buld. So, I need to crimp and solder one of these nipples.

I'm posting a pic of the side of the carb where the needles are. You can see the straight nipple just to the right of the needle. The other 90* nipple is on the other side of the carb.

Which one do I connect to the clunk?

I feel like an idiot---by the way.

Thanks
