Carby problem.

hey,

I have this problem with a stock carby.

When the motor is dead cold, it wants to idle at about 200RPM, when the motor is fully warm it idles at about 800- 900RPM.

I have had the carby rejeted to suit a cam i put in and no change.

has any1 ever had this same problem ??? I know putting another carby will problably fix it.

Cheers.

ur idle solenoid could be buggered, its at the back/top, screws in with 2 screws and has 2 wires coming off it. replace that first and see if that fixes r problem before exchanging the whole carby.

would be choke playing up, mine does it occasionally to , i changed like 4 nikki carbs b4 i got one that the auto choke acvtually worked on. idle stop solenoid would cause irradic idle if it wasnt working at any temps not just when car is cold..... if in doubt bolt on a webber Smile

Idle solenoid aye, but would it work OK once it warmed up??

if so this could b it !!!

As for the auto choke, It goes on and off as it pleases.

I took the gem do a carby pro and he said the carby is in good nic, he didn't c the problem because the motor was fully warm. and i forgot to mention it.

I know he backed the auto choke off, but it made no difference the next morning.

also I have 210 pounds compresstion what does that = in a racio
EG, 9.1:1 8.5:1 10.1:1

thats a different compression ur talking there
also - i'm thinking you might have an air leak in ur carby somewhere, causing it to idle rough
what size cam and jets?
