My V4 seems to be using a lot of petrol and always smells like it's running rich. The plugs are black and it needs no choke to start.
My car has the FoMoCo carb. I've tried lowering the idle and adjusting the volume screw to get the best running but this hasn't helped. Are there any other adjustments/checks I can make ?

Gunson's Colourtune is a nice cheap device for checking your mixture and carb operation.

|26/03/2004 15:39:11||Steve||Thanks for the help guys, I'll check the air bleed jet tonight. Ultimately, if I decide to replace the carb, what do you recommend ? I'm not looking for extra performance particularly, just economy and reliability (it's my daily drive). Any advice ?|

|14/06/2004 10:24:56||Senor Burt||Are you sure it's the carb? Could be timing/ignition/distributor related.
About the only adjustment you can do is the fuel mixture. If this is OK, then maybe the accelorator pump isn't working right. Take off the air filter and look down the carb while moving the linkage fairly fast. You should see a jet of fuel squirting out. If not, the accelerator pump diaphragm may need replacing, or the jet unblocking.
Has it always been like that, or has it just started to happen?
|15/06/2004 12:19:10||Richard||Most likely to be ignition related. Do what Burt says above and if needed take the top off and clean the jets etc(easy on these carbs).|
