Edelbrock 1406 on a 350 that dumps fuel? so much it bogs and dies then I can see fuel pouring in-I checked floats

k5blazer — Sat, 05 Jan 2008 16:21:51 GMT

Fuel then leaks out of the carb and onto the intake. it will idle fine till it warms up (5 min) then it sputters and floods itself out. the idle adjustment screws are only backed out 1 whole turn. What gives? do i need to change the metering jets or rods, install a fuel regulator? help!

The difference between RON and Octane

andres3 — Thu, 24 Jan 2008 16:32:20 GMT

For cars that recommend 95 RON fuel or minimum 93 RON, is that equivalent to 93 Octand and 91 Octane respectively?

Could someone please define RON and how Octane ratings are derived? Why does CA only go up to 91 octane for premium gas? I remember back in the day they had 92 Octane as premium, and in other states I do believe I've still seen 93 as premium. What gives?

Fuel cap and persistent check enine light error, 2008 Honda Civic LX

mrchemo — Sun, 27 Jan 2008 14:51:58 GMT

Hi bought a new 208 honda civic in November, recently I got a check fuel cap error, of course I did and its fine. Then the check engine light came on so i went to the dealership. The error code indicated a vapor leak, but they could not find one and reset it. Then a few day later I get the check fuel cap error and then the check engine light. So I again return to the dealership, again the error code says "SMALL EVAP LEAK DETECTED" and they ordered parts i.e. EVAP CONTROL CANISTER, so I returned to have them install this and the test indicated it was all normal. So I then go along and you guessed it this weekend I get the check fuel cap error and then the check engine light. So now I am back having to go to the dealership, it is a pain in the behind for sure. I note that it seems to happen about 2 days after I have filled up the car and I always check the gas cap to see if its on properly, any one have any suggestions??

2000 GMC 1500 5.3 Won't start cranks fine ran fine when parked 1 week earlier?

notnewchevy — Mon, 12 May 2008 02:16:28 GMT

So everything was fine when I left for vacation. Came back and the truck will not start not even a hick up. Cranks over just fine. The gas gauge shows completely empty. Pretty sure it wasn't when I left it. I added 5 gallons and the gas gauge never moved. Can it have anything to do with the whole fuel system? Fuel pump? Fuel relay? Please help... Thanks

Poor performance 2.3L DOHC LEV

khoppe — Wed, 04 Jun 2008 11:08:57 GMT

I have a problem with engine bucking and poor performance that will come and go. Engine starts fine hot or cold no stalling. The engine bucking is more noticeable when the A/C is on; however, it will smooth out then come back and the can be said for the performance issue. I have tried to follow a sequence of operation to diagnose and found the only clue is it starts to happen when the engine reaches operating temperature. I have replaced the MAP Sensor and it made a marginal improvement. I am now down to the IAC or the MAF sensors or the PCM.
Any suggestions?

What cfm carburetor would work best on a stock Goodwrench 350.

msena1 — Mon, 09 Jun 2008 11:41:49 GMT

I have tried 750cfm, & 600cfm and it would start to fall on its face at a little over half throttle so now I am considering 500cfm.
I am also going from stock cast steel spread bore to Edelbrock performer square bore, dual plane.
I have tried most everything else (that i can think of) and i am now looking at the carburetor.

Fuel line problem when pumping gas.

trooper742 — Tue, 25 Nov 2008 11:20:09 GMT

When pumping gas, the gas nozzle clicks off when the tank is not full. It clicks off about every 2 seconds. Could there be an obstruction in the "neck" of the fuel line between the cap and the tank? I noticed gasoline coming to the top of the line when I have the gas nozzle pulled nearly all the way out.

Is using a coat hanger or plumbing snake safe to use? I'm worried about a spark!

Also, Cannot remember if there was a metal "valve" just under the cap. If there was, it's not there now. Could that have fallen off and be lodged in the neck?

I stopped to by a video and when I tried to start it it would not start. It keeps trying to turn over but will not. I have a new battery and alternator. It is a new van to me, but the plugs and wires look good. I don't think it's the starter, so that leaves me with the pump. I do not hear it going when i turn the key on. Can you tell me what you think and also how much a shop would charge me?

Does anyone know how much diesel fuel is returned to the tank during normal driving (each hour).

robertj9393 — Wed, 01 Jul 2009 12:18:04 GMT

I wish to understand the amount of diesel fuel that is not used in the fuel system and is instead returned to the fuel tank in the return fuel line.

Is this an amount that is predictable?

Edelbrock Carb. Gas pouring out top.

treeterminator — Thu, 28 Aug 2008 10:58:24 GMT

I have an Edelbrock 600 on my old 305 Chevy. Had this carb on for 8 years and has always purred like a kitty. Yesterday I was accelerating around an inclined turn (live in the ozarks), and I put my foot into it to shift down to second (350 turbo trani), and it acted like I ran out of gas, and died. After closer examination, when you turn it over, gas sqirts our of two holes out of the top of the carb. One hole on left and one on right. Comes out pretty heavy and just runs out onto manifold. You think my float is stuck? Any suggestions as to where I should start would be much appreciated. Thanks-John

Do some or certain Jaguar engines suffer from excessive turnover before starting?

corrodedtool — Sun, 28 Sep 2008 19:13:32 GMT

Having read a number of questions submitted, I've noticed that several mentioned the engine turning over excessively before starting. Is this peculiar to the breed/engine? Like some of those mentioned, I've changed the fuel filter, in my case there were two, one in the trunk area, the other in the engine bay.Didn't make any difference.
