Hey guys after taking off the 32/36 off my 4K due to idle problems, I have put the standard 4K carby on which was running fine for a few days. It then developed similar problems to the weber, but the 4K carby has a bit of shaft play. I have replaced the coil pack (after finding it had water in it and was a bit rusted, dizzy points, and I have replaced the perished fuel lines, but it still has the idling problems. I have a standard 3K carby, which I am now putting on, which has no shaft play and appears to be in great condition.

 

Anyone else got any ideas, and what will the 3K carby be like on the 4K. Don't really care about performance at this stage, just need it running reliably as I have it entered in the Bay to Birdwood this Sunday.

 

Thanks, Ben.

I thought the 3k and 4k carbies were exactly the same?? Could be wrong tho :P

Cheers

some 3k carbs are non pollution (this is good)

i think you can put all your 4k jets in it to get the same performance out of it

 

not realy sure as k motors are no longer my cup of coffee

It should go on fine ive got a 4k carby on my 5k engine
