So yesterday I finally got my Holley 600 CFM VS carb installed by a garage that got it running. Today I have the hood open and have the car running and I give it gas and then all of a sudden, a huge flame shoots out almost burning my face. So uhh, what the hell is the deal with this? Thanks.

 

Oh yeah, and does anyone know what to do about singed eyebrows and eyelashes?

 

Well after reading some off your site, it looks like you changed much more than just the carburetor, so it could be a number of things you'll just have to start checking out.

 

Yeah, I put on an Edelbrock Performer, Accel Distributor and cap, Holley carb. My initial thought was timing, could it be something other than that?

 

Check the timing first. In the "old days", we used to say, "75% of carb problems are fixed with a set of plugs & points." Well, we don't use points anymore, but the concept is still the same - Get the ignition up to snuff before messing with the carb.

If the ignition is properly set up and adjusted, then you're looking at a lean condition. Most likely the accelerator pump, but could also be power valve or jetting.

 

Ah crap, you think I blew out the power valve? I heard that's common on Holley's.

 

Well actually Summit here says the 4160's have no jets, power valves, or accelerator pump. The exact number is 80457S if you want/need to know what exactly the carb is.

 

4160's have jets on the primary, but a metering plate on the secondaries. You have a Vacuum secondaries, so you don't have a secondary accelerator pump. You do have a primary pump though.
That 4160 probably has power valve blow out protection, but it should have a primary power valve.

Did you by any chance gun it when the engine was cold, and the choke open?
That would explain the lean back fire.

Hell - mine dosn't have a choke, and if a stomp on it cold it will shoot up.
The Edelbrock (no cloke) I had on previous, did not do this 'AS BAD'. Not sure why the eddies don't flame up like the holley's when cold?

Do you think that would do any damage to anything?

 

Just your eyebrows and eyelashes

I double checked on Holley's website, and yes that model has power valve protection. ohhhh and it's shiny

Yeah and the front of my hair, it didn't seem to like the mousse I had in my hair either.

I guess I'll make sure to leave the throttle alone while the engine is still cold.

 

Thats called a "holley Haircut".

 

:sillylol:

 

Just be glad u didnt just put a fresh coat of hairspray on!

 

I did have mousse, that wasn't pretty.

 

How did you fit a moose in your hair?

 

I would think he would have about had to fit a his hair under a moose to do that, but it would take an awful lot of talent to do that and work on the car at the same time.

:lala:

 

make sure the distributer aint in 180 off if you changed the intake

 

No no no no, I have a moose for a hood. The antlers work really well as a brush guard.

 

Rock on. Screw painting my car, I am going to do it in animal skins. lol

 

You probably singed the fur on your moose hood, too. Might want to consult the appearance board on fixing it.
