Hello everyone, can any one give any sound advice on the following...
ok, i have finally found out that i have a fueling problem with my engine. If i put fuel direct into the jet it fires but otherwise it wont fire, have taken off carb cleaned out etc put on a new interupter fuel pump but still not working. Think im gonna have to find a different carb and try off that? Anyone had problems like this.
cheers

Yeah floats are full of full took the whole thing off and rebuilt it as it seemed before that the jets might be blocked. The only thing i can now think is that maybe i got the wrong fuel pump? Although the compression is 110 is that good or bad for a a+ series engine?

the float should have no fuel in it

the needle valves wear badly and the throttle spindle bushes wear allowing air leaks.

ok so what size carb have you got on what size engine ?
the lack of vacume could be two things , has the manifold been recently disturbed or taken off or stage 1'd ?
if yes has the gasket been replaced ?or have you used the old one and not noticed a chunk missing ?
have you checked that all the nuts on both stages of the carb and manifold are tight ?
have you checked the tube that runs from the flame trap on the end of the engine to the carb has not cracked or fallen off?
is the engine an injection or a carb fueled?
if you are trying to run a hiff44 on a 1000 cc it does lack in good feelable induction and can be quite difficault to tune ref to ac dodd evening .

think were going round in circles with this one . Start at the beginning
as Tim and Shawn have said what carb what engine what mods above standard speck does it have , and what is it doing, did it only start after something else was replaced repaired etc. .
Hope we can sort it

Hey well.... as far as i know my engine is a 1430cc with a stage 4 head, unknown cam and it has weber 45 dcoe. Have recently changed all the fuel lines as the previous owner had mixed lines to the carb, going from 1/4 to 5/16`s. And also put on a uprated fuel pump, the car now fires but is not running very well timing seems to be way off. Seem to have a problem moving the dizzy ...... it is a a+ engine with the c clamp but the nut is in the way of the amp on the side of body of the dizzy so wont turn any further? Anyone got a a+ and know how i can get the dizzy to move round? Thought of shearing the bolt down but there must be someway of moving it?
cheers

bloody hell , there we all are thinking , 998cc with a peco and a pancake and you have something a bit wilder.
You can see why more info helps .
All yours Dr. Had no dealings with webers , bet a rolling road session will help once you have it running semi sensibly.
Re the distributor , take the bolt and clamp off altogether to give free movement of the distributor just to see if turning it will help it start only . May have the wrong clamp/bolt . The dizzy will not be really loose without them but SECURE THE DIZZY BEFORE RUNNING IT PROPERLY , ONLY HAVE IT LOOSE TO SEE IF IT STARTS . Dont want to damage things .

a silly quistion but has it go the o rings fitted between carb and manifold? and thackery washers on the nuts allowing the carb to move over tighten and it will never run, if a hairy cam i would start around 4000rpm 28 deg full advance but really needs rollers

Yeah definitely plan was to get it running then take it over to gerald dale..... and let him take all my hard earned money! lol
Not to sure a friend rebuilt the carb for me and gave me this spec....
main jet 170
emulsion tube f2
air correction 160
idle jet 50f8
needle valve 2.25
i just bought a hif44 off ebay so might give that a bash in a few days and see what happens!
cheers
