Hello everyone, I just bought a new 21mm carb and a SSP-G preformance intake...my quick question is what are the 2 nipples on the intake for? Does something from the carb hook up to it? Thanks for any help as the stock intake doesn’t have it Lol  |

Vacuum ports for a fuel petcock or fuel pump. Dunno why there are two though.

Both vacuum lines. Different sizes so you have a choice of what fits your application best

So I could hook the fuel line to one and cap the other? I’m going to see what instructions if any come with it when it arrives on Monday. Thanks for the help

The small one is for oil line input.
I would take both of those out and put thread sealant on them by the way. I would also sand the mounting surface flat and use a good sealant.

Do not hook the fuel line to those!

So I believe I’m going to just seal them off if they’re not needed... new carb should not interfere with it. Thanks everyone for your knowledge and advice

::Update:: I installed my 70cc bbk,pref intake and 21mm OKO carb... the carb doesn’t have a spot for the oil line like the stock one! Where would I put that oil line? The smaller of the two nipples on the intake? I really didn’t want to do premix if I can still utilize the oil tank ect... Thanks a million Mike

On the intake yes. |

Thanks Rune75... that’s what I was leaning towards just wanted to make sure it’s right and not sure why nothing on the carb for it. Guess all are made different lol. Thanks again bro

Does a PWK even work (well) on a 2-stroke?. Seems like it’s missing some things.

I use CT intake manifolds, they look like the one in your picture. I use the smaller nipple for the oil injection. I use to use the larger nipple for vacuum to open the petcock. At one point I redrilled and tapped the large nipple hole and installed a larger barbed fitting so I could run a bigger vacuum hose. After a while I ditched the vacuum petcock for a manual shut off valve. At that point, I used my large barbed fitting to hook up a boost bottle, which I later removed.
