3Y Engine - idling eratically

[SUKIBOS]

Eventually the Suzuki Vitara with brand new 3Y Engine started,
everything sorted except, the idling - she doesn't idle below 1500 rpm, and the ref counter plays up and down between 1500 & 1700. The timing is set a 8 degrees BTDC, any idees on what's causing this. She runs "windgat" except for the fact that she's going to be very thirsty with her idling so high. I cannot set the idling screw more, she dies below 1500 rpm.

Ag asseblief, iemand help tog net. My vrou moet asb. nog hierdie week haar eie kar begin ry - my bakkie lyk soos 'n asgat!! (koeldrank blikke, tissues & sweets papiere)!!! Om nie eers te praat van die weg gesteekte droë wors onder die seat nie!!

Are the electricals and vacuums correctly connected? ...... could be it's sucking air on a vacuum hose.

Thank you for the suggestion, it got me thinking... the suzuki had 3 fuel lines, one is an extra line that was connected to a charcoal canister for emission control, fitting the 3Y there is no need for the canister. I blocked the line, but I think that maybe she is still somehow getting air through that line. I will remove that fuel line and block it off at the tank, I hope that works.

Have you connected an ignition positive to the idle cut-off valve solenoid? If this solenoid isn't energised when the engine running, it won't idle no matter what!

After spending alot of money taking the car to a mechanic, still we weren't sorted with the 3Y. I took the wiring diagram and studied it for the 7000th time an whallla!!! The solution: the carburator was missing a ground wire - CAN YOU BELIEVE IT!!! After months of battling, sore hands, frustration , it's a blerrie WIRE!!! :alvarin: :alvarin: :alvarin: :alvarin:
Thanks for everybody's advise. It was the best move to fit the 3Y into the Suzuki, she runs like a dream!!

Glad you came right - I could have sworn I answered this post with exactly that suggestion a week or ago???

Maybe it was another 3Y??

I learned the hardway too on an engine transplant in my golf. damn earth strap wire prevented the idle shut-off valve from grounding
