QUICK FUEL CARB ?

Looks like plain old corrosion to me... But then again I am on the coast and have never had a carb look like that. But my small block did have the gritty exhaust ports from running VP C-12.

so i took some wd-40 and clean one up and there is a slight pitting in the machined marks ..........

I stored my car in the trailer over the winter one year and checked on it from time to time and as it got colder frost developed on my valve covers and headers when the frost went away it left deposits like that. I just polished it off with mothers, but there was some permanent pitting. Im assuming that since your so far south frost is rarely an issue, but condensation would likely oxidize the same. I always put my carb in a sealed box and put it on the shelf in the winter so come spring time there isnt any drama.

i just wonder why my prosystems carb never did that ???

Its got to be moisture from condensation, seems the last outing you were in some cool air.

WD40 fog after race.

For the winter I like to pull my carb off, clean it out with some brakeclean and WD40 the snot out of it, seal in a bag, put it in a box.

I agree with Jon Nick, I'd be for pullin the bowls off, maybe even pull the carb apart and give it a good cleaning... It does look like it's been there awhile, I'd bet it was caused from the high humidity and salty air from Florida...

X2 on pullin' the carb off during the off season for a hose down and WD-40 fog...

The carb did not do 'it' . Something in the air or fuel .

X2, the brand of carb has nothing to do with "it"!

Thats some Nasty lookin shit Nick, better get that thing cleaned up Quick. If its in the fuel,your regulator, Alum lines, and Fuel pump need to be checked also.

that carb is garbage .............. i will take it off your hands ....... j/k if the bowls look good then it is not fuel has to be some kind of condensation ....... if my memory serves me right werent you the one that had the pissing edelbrock head ............ i would run a pressure test and see if that head is pissing liquids again .....maybe just steaming after a run .......... thats just too much normal condensation

just my .02

forgot bout the pissy head, x2 on checking it

I'm thinking its the chemicals in the "hot" fuel you've been running, stuffs pretty nasty.....

was it monster 114 or monster ox 114?

pretty or nasty ?
Question is.......what does the top of the butterflies look like ? If/when they are relatively cool looking....gotta think that it's something going on when the engine is not running .

the top of the bowls look like brand new Lem ........... im thinking that head is pissing some steam ??? ... i hope not ------ but there is no telling ......

not the bowls...the butterflies.........

Finally had a chance to read this thread.

My QF carb had the same thing happen to it... But I run VP C-12.
I'm almost positive it's corrosion/ rust from condensation after the car has been run IN COOLER weather...
I say this, because I also found condensation in the valve covers when checking the valves..

Maybe...Just Maybe ???

A maybe + here .

the top side of the butterfly's look good also Lem

Well....it's happening when the throttle is closed . When the engine is at W.O.T. the fuel is seeing both sides of the butterflies ...........case closed.

Motor warm, carb cool / cold ( especially when using phenolc carb spacer) car put into a cool/cold trailer on a cool / cold night. Yup..sounds like condensation to me..

here are some added pics ......... everything looks great in these pics

The Godfather has spoken, heed his words...

yep, def condensation.....prolly mixing with the fuel residue and making a mess.

Alky guys are already fighting moisture from the get go, so after race procedures are already in place.

Fog with WD40, pull the plugs and breathers, prop the throttle open if need be.

As a long time monster fuel dealer and a racer that has alot of experience with the Q16 I have never seen either fuel do that. I have seen carbs that have seen moisture or severe weather changes appear that way. Charlie if you are talking about the carbs that I used I never ran your metering blocks or float bowls. I just used the main body for testing. So any residue in the bowl would have been from something else. Nick if you need anything for your carb give me a call and I can help.
