There are 3 ports on the right side of the carb.1 is for the gas feed (brass on the bottem), 2 is vac turn on for fuel(wich one of the top two ?), what is the third one for(top hose on the oil tank)?

 

one more question how do i hook up the oil injector hoses where do they go. ( incase anyone is wondering I got this quad in a couple of boxes) any help is would be great.

 

the one with the brass end on the right side is for the oil injector line.
the lower and middle one on the left is to the fuel bowl from the petcock, the forward one I think is a vent line, I could not see were it went. the back one on he left is suppose to be the vacuum line but I cant get mine to work. I capped it and used a banshee petcock (no vacuum).

hope that helps

 

thanks for the reply ddtia

 

The lil tiny brass fitting on the LEFT side is the oil injection.
On the RIGHT side there are 3 holes. The big brass is the fuel the front upper hole is the vent, rear upper is the vaccum to the petcock.

 

thanks lt 80 that works for me.

 

The rear upper 'vacum vent to the petcock' - is there supposed to be a hose attached to this? Mine won't start, and I think it's the carb somehow (floods out). I have the fuel, oil, and other cables hooked up correctly. It's just the top aluminum nipple coming off the part that attaches the carb to the reed valves.

 

Yes there is supposed to be a hose on there. It goes to the petcock.

 

My appologies - I forgot to mention that I'm an idiot. What is a petcock? Where is that on the motorcycle?

Again - thanks for the help..

 

The petcock is the on and off valve on your gas tank
