Well, this has been a good weekend..i didn't break anything too expensive (one of the stupid plastic delay valves in the rats nest broke when i was removing it..damn brittle plastic!)

anyway... heres what all i got done:

1. passenger lock fixed
2. fender taken off
3. door realigned (still doesnt close right)
4. put stuff back on carb, going to put it back on soon...
5. found the dreaded idle speed screw and noticed that my carb has a CAP Over the mixture screw! its metal and theirs no way to get it off ! dammit!
6. took off the rats nest, preped to replace all the hoses...anyone got any pictures of their nest? i need several angles of it if you dont mind, im rebuilding mine and im having trouble finding where one of the lines go to...
7. degreased! prepping for engine removal.... i know i know degrease while its out..yeah well i wanted to be able to see my rotor housings..lol
8. decided that pulling the tranny and engine at the same time is the best bet... k well now that thats established..time to find a hoist!
9. raped my battery of all its power..woo its dead now..
10. aligned my hoodlatch so that my hood pops open correctly..yay!
11. put new coolant level sensor in and got all the lights on the idiot panel to go out now i have no warning lights

ok: so heres what i need help on... and ive searched...so dont attack me...

1. whats gives better exhaust flame *****? rats nest? or no rats nest? ive read conflicting posts....
2. i dont have emissions tests and i cant afford a "test pipe" for my exhaust right now so im having to run stock..will using the stock cats IF i dont care about their functioning hurt the performance of my car? or just burn the cat up?
3. can someone please post several angled shots of their rats nest? or the lack of? i need pictures to go by one guy had several good shots of his nest but the page is dead now... deal52.com something or other..anyway..

and the last one...
4. which hole on the carb plate do i need to leave open? Ive read conflicting information..some say cover all, some say theirs one that is left open.. any info?


thanks guys its...slowly getting there

A stock Nikki carb on a stock motor should not be shooting large flames or big backfires out the exhaust. If yours is, it is likely because something is not working properly. Usually, stock setups with rats nests intact shoot flames, while no rats nest = no flames. I believe this has something to do with a common malfunction of the shutter valve.... (mine shot flames and huge backfires with the rats nest, *nothing* without)

Now, this varies with the exhaust setup... my RB system with the regular Primaflow muffler did not shoot flames after removal of the rats nest. However, the swap to a dual connecting pipe and RB dual-entry streetport muffler yielded stronger backfires, and now with my Dellorto carb setup I get flames a-plenty. Go figure....

Anyways, if you have a stock carb your goal should be a properly running setup, which likely means no flames or big backfires.

Your goal should not be "which gives better flames."

Flames do not mean your car is running right, or you have a fast car. Unless you're acting in the Fast and the Furious that is LOL.

What specific setup are you referring to? If you run your stock cats without an air pump, you'll melt them. This will hurt your performance. If you haven't removed your cats, *do not* remove anything else. Leave it all until you can afford to do it right. Patience is a virtue when messing with cars, and doing things half-assed leads to half-assed results.

Every manual (and pasted on your hood for that matter) has a diagram of the rats nest, showing where everything goes and what everything's for.

Plug everything on the bottom plate. The only thing to leave open is the air vent higher up on the carb (will be labeled "air vent solenoid" in your manual). Also leave the distributor vacuum pots open. This is all available by searching.

Leave the vaccum advance diaphram things on the distributor open as well .

Oh, and put a filter on the oil breather thing

What part of Birmingham do you live in? Back when my car was somewhat close to stock I did the rats nest thing, I can help you out.

slingo

i live in tarrant..
btw the only reason i wanted fireballs is to **** people off, its not a big deal.. i thought that if rats nest gave bigger ***** then when i had the money to redo all the vacuum tubing i would reinstall it... my goals to get the car running smoothly...and my nest is trash, so i took it off as such..all the tubes are cracked / rotted, the delay valves are brittle and one already broke, the black purge valve cracked in half..this is why im removing it... its ****, btw, if i had money to replace the cats i would..if they melt, that'll give me an excuse to buy the pipe.. i had planned on the oil neck breather (the question is..what kind? where can i find one this small ?) sorry if i was misleading in the things i said... ill probably fab up a pipe at school using the flanges off the old converters..its ghetto but it'll work...

Felix: appreciate the help, as i said before, im in tarrant... dont worry about it, i got the nest removed, all ive gotta do is buy some block off nubs and a breather for the oil neck.. i should have the ACV plate before i put the engine back in the car (the engines coming out this weekend, ill order the ACV plate and some new gaskets from RB this next week, in 2 weeks i should have a new clutch for the engine.. and hopefully by 3-5 weeks from now my car should be back together and rolling down the road...

btw.. hope i dont blow those imaginary welds on the intake manifold lol
TF&F = not my goal..but you gotta admit 2 foot blue flame ***** are cool.

oh..one last question.. i was looking in the Victoria British catalog, they have some nice chromed headers which are split, one per pipe and they go into a converter which makes them into one, i was thinking maybe some custom fab work and i could have a true dual exhaust they are the Monza headers ... look to be pretty nice.. i was thinking take a hacksaw to the converter that turns it two into one, weld seperate pipes on, a pair of small presilencers and 2 mufflers, dual exhaust.. wonder how it would perform..... ive heard single is better but im wondering if a TRUE dual not a Y'ed off wanna be dual exhaust would perform as good as a single exhaust / or better... hmm anyway... dont crack at me about my little idea.. i like to be out of the ordinary
--------------------------------------------------------------
nevermind someone just told me monza headers were crap..figures :|

I bought a breather from Autozone in the APC aisle. I haven' t put it on yet, but it doesn't look like it will take too much.

My car threw flames when it had just some exhaust and stock everything else.

Yes Monza headers suck, I had one and gave it to my brother. The welds on the flange cracked a couple weeks ago.

I knew a girl that lived in Tarrant about 5 years ago. That was the last time I went out there, and I only had to go a little bit off of 79. I've never gone anywhere else there besides Smith Bros.

RB's road/race headers look exactly like the monzas and they sell flanges i may buy those and do the same

breather = oil neck breather (we're on the same page here right?)

anyway, ive got to rip the nest off or repair it ... the nest is already ripped off and im going to buy the caps tommorrow if i have enough money.

Felix Wankel

They may look the same but they are not. RB headers have MUCH thicker tubes and flanges, better welds, better fitments, etc. Plus the RB headers have equal lentgh tubes, the Monzas don't.

Pace Setter/Monza sucks. Even for what little they cost.

Yes breather= oil filler neck breather.

SilverRocket

Just go to any autoparts store, tell them you want a PCV breather filter. They come with an adjustable rubber inlet so you can clamp it over the filler neck. The one I got looks like a little K&N, but it's just a cheapy lol.

okie dokie i meant that the RB's have the same design so i could do the same thing with them that i was going to do with the monzas... yes, rb kicks ***
