Annoying Rattle in Vk

[gone_nutz13]

My Carby Vk has an annoying rattle, at first i thought it might be the dizzy gear about to go, i pulled that out, gear is fine, rattles about half to full acceleration, but on using the second barrel the rattle goes away, when cruising on little acceleration also no rattle. lol thoughts?

what does it sound like?

is it definitely coming from the engine??

yeah it's definately coming from the engine, it sounds like a gear rattling noise, but only when engine is warm and accelerating or going up hills, nothing harsh, just really annoying, makes it sound like a heap

What fuel are you running in it?

 

[gone_nutz13]

unleaded with additive, engine runs perfectly sweet, just that stupid thing, i thought it was the dizzy gear, but that was fine so i got a bit stumped

I think i know what it is now

Your air pump take the belt off the air pump and see if it still does it. My Carbie VK used to do it sometimes. Nothing serious if you are really worried about it you can pull it appart and give it a lube.


cheers

the air pump is a great piece of engineering!...is pumps air into the exhaust manifold, utterly useless and robs power from the engine...arent ADR's great?

 

[gone_nutz13]

thats the thing on the carby side of the engine on top hey, yeah adr's are good, giving good cars yellow stickers and robbing power, thanks for that, i'll give it a try this arvo and let you know

 

[gone_nutz13]

yeah took the belt off of the compressor, rattle seems to have gone, however should i put it back on? due to cops, yellow stickers etc? as i'm a p plater the less attention the better, do you get any sort of economical gains with having it disconnected, what about having my air con belt off aswell?

 

[haloeight]

if u leave the thing there but disconnected unless they hardcore want to defect you for driving like a looney you should be fine.
