Keep it and take the gun off it. Hunting solved.

My van did this it was brake related, but clean the carb too

[mightymanx]

i have gave the carb a good squirt of carb cleaner and looks pretty clean through the top of the carb lobster?

Has it got a dump valve? Mine did this and it was a split diaphragm. Or a leak somewhere on the vacuums lines

[mightymanx]

it does have a dump valve yer i could try replaceing that and ill check the vacum hoses again or wich bits of the carb do i need to clean

[SCHWARTZ]

Get the dump valve off and get a carb service kit from the shop give the carb a good overall and measure the jets while its apart so you know how its setup;)

i always like a 5 gtt with a dump valve i have a spare ill try that lol ok ill get a carb service kit is this it?

That's it

[mightymanx]

ok the car also has a bleed valve and a in car boost could any of these be the problem has a weird pipeing set up ich ill get pics for

[mightymanx]

ok tryed replaceing the dump valve and bblocking off the bleed valve and in car boost and it still is hunty so i will get a carb refurb kit it has to be that i have uploaded a pic of the engine can people look at it and tell me if the carb vacuum hoses etc are rite? http://imageshack.us/photo/my-images/600/engine002.jpg/

Have you checked that the inlet manifold and the exhaust manifold nuts are tightly tight :)

Sprayed a bit of carb cleaner around the carb to see if the note of the engine changes, indicating a leak. :confused:

[mightymanx]

i have checked all the manifold nuts turbo carb and all surrounding nuts was my 1st job also checked whole exhaust everything is tite is driving me nuts

[mightymanx]

any 1 any other ideas could the idle screw need cleaning>?

[James5]

Have you not noticed that your turbo actuator is piped up wrong and the bleed valve is funny I can see what they have done using the bleed valve as the max boost setting ditch the in car and just use actuator and if more needed use the bleed valve. make sure your AEI line is plumbed incorrect also should go to inlet and have a T in for your crap valve.

Think your best getting a carb service kit, and re-doing all the carb vacum hoses again also replace the idle screw O'ring (Big brass screw on side of carb) and get yourself a new mix screw as this could also be part of cause.

Hunting is down to an air leak as already mentioned by other's.
