Craig, tryed that 12 years ago...didn't work then, prolly not now either, better off working with turtles and fuel dividers.

I am really banging my head here ....the car is jacked up and layed over and i think that it is starving the jets on the left side??? I was wondering if i level the carb out it would help get fuel to the 3 and 5.....the rest of the plugs look good tad bit of yellowish orange collor to the pocelin but 3 and 5 burnt the centers down???

After checking my car it sits at 10 deg angle allmost all the way around the track. Now i took a metering block and put it at 10 deg and it will put the fuel to one side allowing the other jets to get air ....thats what im thinking...my car goes in on the bottom hard and turns so you have to add the force also...

Draime enterprises (330)837 2254 be prepared though i think they are like 250$ ea.

Also Stealth carbureretion sells them i think for a little less but I cant find the number for him right now. WE are currently using one of these on our mod. The guy we bought the motor from thought it worked better with this spacer so he is letting us borrow it and we have never tried anythign else..

Might also try to contact KPLugnut he might be able to get them too.

Have CNC mill can make you one. How much do you need it angled, 10 Degs?? Also how tall, 4 hole, open, half & half??? lets talk if you haven;t found one yet.

I have a mill and was gonna use a 1" open spacer and cut it at 10 deg...the only problem i see is that the bolts would have to change to 10 deg...not sure how i will do that?? I also spent some time with willys Carbs and there carbs have a tube in the bowl that goes to the right side to avoid this..

You're correct that the left cylinders will run leaner on almost any circle track motor. My engine builders think that the centrifugal force actually works on the fuel as it is suspended in the air and moves just a little extra to the right side. We just tune to the left side cylinders and let the rights run a little rich. Also, do you have a circle track float(wedge shaped). If you don't, when the fuel moves over to the right side of the bowls it can cause the float to close up the needle valve, lowering the overall volume in the bowl.With the wedge float you shouldn't have that problem.

dirtracer14, Using a wedge spacer you will probably have to elongate the holes in the base plate & I would recommend making a wedged spacer/washer that is matched to the amount of angle of your spacer for the 4 bolts holding the carb down not too tough.
JWS where can I get some of these floats???
Dirtracer14 I'm assuming the tube you're refering to was attached to the left jet?

Ford5 is right wood is a great insolator from heat and easy to work with I've used marine No.1 plywood with epoxy as a sealer works great.

Are you all talking about the spacers that are wedged one way like front to back or the ones that are wedged front to back and side to side, so that it is tipped down to the left and to the back?

All the above!! I'm interested if you or anyone has tried & how they felt about them. Also did anyone ever try it with & without it on the same nite to sort of "measure" the value of it? I'm sure that these things would require a small adjustment to jetting with or without the spacer. I'm of the mindset that an engine running anything above 4500 rpm is gone **** fuel into the requesting cylinder. Things like pulses and reversion come into play here too but, with the tuneup being a tad fat on most cars & the broad margin of error for the mixture it would seem that if you're leam on any cylinder on the left you're just too lean and need to move up a step or so.

I plan on making wedge spacer to bolt it on. The carb slid down without binding but just to make sure it seals and not breaks ill make some. I will let evryone know how it works or how it didnt. I really think that it is my problem here...and maybe the little bit of angle will help.. Yep i thought about the float as well when it lays over the fuel is closing the float early....i would love to try one of those floats...were ya get em?

Craig, have you tried a plenum divider? I have a Barry Grant one I bought from Rapp, it basically is a 1/2 spacer with a plenum plate in it. If you would like to try it I could try and get it up to you.

I have read somethings before about centrifugal force and the tilting of the chassis on not only carbs but engines in general. The banking of the track has alot to do with it higher bank the less things roll to the right. but then on a flatter track with a car all hiked up i do see an issue but not only carbs but the way the oil behaves in the crank case in the wet sump engine. On that note I would and think one time a long time ago I have seen engines tilted to the left in the chassis. I believe some of the east coast asphalt mods do this. Just some thoughts.

on big diesel trucks the engines are tilted a few degrees.

It's been awhile since I bought circle track floats. I think that you can get them about anywhere that has lots of carb supplies. Maybe even Summit or Jeg's. I think BG made made mine. You need a set with a front and rear for a 4 barrel. A high end reworked carb or a circle track demon should already have them in it.

You can get the floats from summit or anywhere like that, moroso makes them but if you run alky i wouldnt reccomend it. They are just a standard foam float cut at an angle then sealed with epoxy. The alky will eat the epoxy off and ruin the float. Braswell makes some that are actually molded that way and not cut but they are about twice the money. Just FYI.

Well i tried the tilted spacer...burnt the plug in hot laps when it was tacky but after the track locked down i was able to run all night without losing the plug. I think im getting closer just looks like i need to bring the jets up on the left side...How many of you guys stagger jet?

I stagger jet & use a plywood 1" spacer no angle. Have yet to lose a plug. I'm 2 sizes higher on the left vs the right. Motor pulls clean. Track has average banking and is on the short side.

We run a Braswell and it is 2 thousandths fatter on the left side from Braswell.No problems.
