idle jet????

[Kerrod]

i'm not to sure on how to get to that, thats all!

[dj181]

ummmm i am trying to remember myself....i USED to have some photos of it, but i dont have them anymore.........from memory, if u take the top of the carby off, you will see a hole. on top near the fuel cut off solenoid.....the idle jet is down inside it......would be good if someone else had a pic of the idle jet on a sierra carby........

clamp teh brake booster vacuum hose and try it, BE CAREFUL YOU WONT HAVE VERY GOOD BRAKES

i have had this trouble for a few weeks until someone showed me how to take the carby apart and clean out the idle jet. It's easy if someone shows you.

carbie from the top if its any help.. gives you guys something to draw on anyway!

only recently fixed my idleing dramas with the fuel filter after the fuel pump.. Not a worry or hesitation since..

ok if u take the top of the carby off and have a look at the area right next to the fuel cut off solenoid and the accelerator pump, there will be a small jet inside there. it is VERY small...and gets blocked up very easily. and it would prob be a good idea to give you carby a good clean out while you have the top off (if u decide to do it!!)



it should be in the area i have marked with the circle

thanks, i found it and it was blocked, it does idle better but still dies when i'm goin to stop at lights etc.... and when i engine brake when goin to stop it bac fires very loud

[dj181]

also check the fuel solenoid.....and make sure it is working ok.....apart from that all i can recommend is to give it all a good clean to make sure that there is no more crap in the carby that is going to get sucked back into the idle jet....and put a new fuel filter on maybe???put one on after the fuel pump just before the carby.....

i had a LOT of problems with my old sierra carby with this sort of problem and once i had done all that to it it seemed to work ok

[Kerrod]

how do u check if its workin ok?yea i already have a filter on there!

i'll have another go 2morro

thanks for that

[dj181]

if u pull the fuel solenoid out and hold the metal body of it onto the negative of the battery and then put the wire coming off the solenoid onto the positive. u should hear and feel it click, and u should be able to see the needle inside it move (i think)

If you found crap just just after the fuel solenoid, chances are that there more through the whole thing. Think a full tear now and clean will be your best bet.
