Mine was I just had to set the Idle and after I had a few passes had to go up 4 jet sizes front and rear.

Must be for shipping purposes looks as the adjustment screw all the way in.Or i need adjust the 12-704 reg to lower the pressure.

What's your fuel PSI on ? I think 7.5 psi is where I would put it to start with!

float level should be in the center of the sight glass.

Both new and when i prime it feeled the sight glass and i stop until i could ask some guys on here for some info.12-704 which way lowers the pressure up or down with the adjustment screw?

I have no idea why they would have been all the way in,
Turn them all out 1 1/4 to 1 1/2 for a base line. Set your fuel pressure to between 7 to 8 lbs except SV-1 Alky. Pro systems usually have built in sight glasses on all 4 corners w/mark 1/2 way on the glass to set fuel in bowl. Mine was dead on except idle out of box.

Will it hurt anything to leave the fuel pump on until i can adjust the reg?

Gas or Alky ?

Gas, it may just be me guys i have been paying to do this in the past. Looks as it was easier that way lol

i loosed the set screws after i read to reset the float i may have messup....But they did look to be screwed all way down

Rick, do u mean if thier all the way screw in to turn one full turn out and then a half of another for a baseline?

Don't turn them in tight(just till they stop).Then turn out 1 turn,then another 1/4or1/2.

I think most of you guys are telling bigjohn how to set the idle mixtures and he is asking about the float level. John you need a 5/8 wrench and a wide blade straight screwdriver to set the float level. Turn the nut clockwise will lower the float level counterclockwise will raise it. You need to lower it so I would pull the carb off and drain the bowls then turn the nut/screw down a few turns then put it back on and turn the pump on. Its easier to raise them than lower because the fuel has to be drained out or run it enough to use the fuel in the bowl. If you start low you can see the level come up when you turn the nut. I keep the screw snug as I'm moving the nut so less fuel squirts out.

I miss read It was late and I was tired ! Sorry big John if I miss informed you!

needs to be runnin to set the float correctly. The float level itself can depend on other things also. Honestly thats one of the things you wouldnt have to mess with on a new pro built carb I would think. It should have been set up for a specific ptressure to begin with.

Rich,it may have been but it being my first time when i read to reset floats i loosing the nut and thought i would have to adjust it for the fuel to begin to go in the bowls but instead it feeled them.

Every pro system I've had if I gave the right info when ordering it. Its been perfect out of the box. Just set idle and go.guess I've just been lucky or Patrick knows I'm a retard and he needs to get it right.r

Well drain the carb turn fuel pump on set the reg. 6.5 psi and got the sight glass level on front bowl right then the back but when i looked at the reg. it was creeping up.Is this normal or not the reg. is new?

If deadhead then yes

shouldnt creep if its running.....

Gues I should have mentioned that^^^

Where can i get a throttle cable bracket bolts on the side of the carb my old one won't work?

If it creep and not running what could be the problem?
