carby problem car running rough car drinking to much fuel. any sujestions as to what this problem could be?

Could need a re-jet. What size engine is it and what size carby are you running? If its too big then thats your problem right there I would say. Anyways, let us know.

Best fix, convert to EFI, but if you're budget doesn't go that far, get the carby tuned. My car with the carby engine was good for 260 k's to a tank around town, so they are not that great and it was running sweet as then too. Now i get over 400 with the injection. Is it still the rochester?? There are a good carby and capable of supplying fuel to some pretty big hp numbers. I had one on my former Brock which made 273 at the treads, was way more driveable than when it had the Holley on it and made the same horsepower. sorry, i digress. Speak to you local carby shop for some advice. Cheers.

hey injection what'd the complete changeover cost? r u able to post some of your costs? i.e. parts list and price, and where u got the engineering, etc. done? That v8 i messaged about is still for sale and still weighing on my mind...

nah cant afford to get efi ... its standard 5litre no mods done to it yet i just changed the carby with another standard one. it needs a new auto any ideas on price of trimatic auto, and any sujestuions of good place i could take it to in melb. are thermo fans a good investment my car overheated yesterday in 30deg day only in a 20min drive. thanks guys

the roche's are a bit trickier than ye ol holley to tune, so have a hunt around for a workshop who actually knows specifically about those carbs, not just any bob mechanic and no, thermo fans are not a wise investment, find out why your car is overheating instead. the belt driven fan moves a ****load of air...

All up it prolly cost me a bit over $5K, but most of the stuff was brand new, like motor, heads, water and oil pumps,bolts, u name it. I'm still writing the tech article on the conversion for it on my site, so keep an eye out in a few more weeks as it's very detailed. You could do the conversion for a fair bit less using a wreck and depends n how mu h you do yourself. We should catch up one day and I can show you the conversion and have a good chat to ya about it. If u can, come to the Commodore Car Club of WA meeting on 6 Jan 2002, Troy Park Hall, Burke Dve Attadale 7.15 (meeting starts at 7.30) and I'll chat to ya then

the man for the job on the carby is named neil he is located in preston the shop is called everite motors this guy is a wizz with rochesters he is the only guy in aus thats made a series 1,2,3,4 rochester so talk to him and tell him what mods u plan to do and hell build the carb to those specs
