hey guys cant find old post on spark plug resistance per foot ? got two plugs not firing, changed plugs & wires,rotor &cap and module and coil, new distributor from jegs.wonder if wires to long?350 chevy crate engine.also it is
#2 and #7 last in firing order ?
soup
thanks denny i will check wire resistance and location
soup
I think for resistance wires it's up to 7000 ohms per foot.
i get a reading of 65 on the 200k scale ? soup
wires are new accel performance soup
most car manufacturers allow resistance up to 2000-3000ohms per foot, but high performance wires get MUCH lower
IMHO 2 to 3k per foot is UNACCEPTABLE and Accell super stock have that problem and it gets worse with age. My advice would be to trash the wires and buy some Moroso, MSD, Taylor spiral core, etc.
The resistance is for radio noise suppresion. Most engines in the past 50 years use resistance plugs to generate the resistance and use low resistance wires. But, since he mentioned resistance wire I thought I would throw out a typical number for a resistance wire.
hey guys thanks for info , just replaced two wet plugs and went for a ride , started out good ,but when i got back two plugs are wet and six others are carbuned up,got bright white slightly yellow spark on all,i have eldlebrock 600 on it (brand new ) my wet plugs might be jet problem? why two are wet and rest slightly black ? soup
mixture on carb set with lean drop method and i have steady 19 on vac gauge ,but spark has yellowish colour to it , got another coil to try let you know what happens
soup
If you went from points to electronic ignition, you need to get rid of the ballast resistor.
no i pulled 305 put in 350crate engine, everything on 350(chevy) is new,1984 el camino,engine has been fussy,changed carb,dist. manifold(intake)fuel pump,may have tp put another set of better wires on and change ac plugs to ngk iridium ?
soup
I don't believe the plugs are the problem, the Accell wires are.
I hate to hammer Accell, bit I've had two of their super coils fail and three of their Super Stock plug wires sets with up to 15k resistance in individual wires. The Super Coils do make good bookends though. :( :LOL: :LOL:
i dont think i know too many people that have had an accel part last them more than a month
Yep, but not in that order. 1-8-4-3-6-5-7-2Quote:
also it is #2 and #7 last in firing order ?
odered msd wires, new rotor and cap (msd) had accel cap and rotor let you know what happens
And a MSD 6A to go with it would help LOTS. :cool:
an msd box is overkill.... an HEI would work plenty good
Burning a higher percent of the fuel charge in a cylinder is overkill :HMMM:Quote:

I have an extra set of wires I am going to try tonight after cleaning the plugs completely.
I had considered MSD, but like the simplicity of HEI, and it must work, because many people run them.
Interested to see what your result is. Keep us updated.
FYI - here is a picture of my HEI and wire setup (wires very close together, and one on the cap touches the air cleaner assembly when installed). Is it possible that if plugs are excessively black (I have just fixed the rich problem) that they would be less likely to fire? I'm getting frustrated. Installed the Jeep engine this last winter and haven't driven it more than 20 minutes total.

okay put new 8.5 msd wires ,cap and rotor on, plugs cleaner after run to town ,still have flat spot or bog on take off,timing 10,vac 19 , seems to load up with gas ,phoned edlebrock they say i might have to jet down(new 1406)
i am wondering if it is carb or distribuutor springs ?after 1700 rpm she goes,but not from stading start.
does she smell rich to you? you should smell it clearly if you've got a rich condition..... if you have a lean condition you wont smell much gas at all...
automatic , plugs set at 45,new hei with adjustable vac advance hooked to manifold,jegs says to start vac advance at 4 turns i am up to six now,4 turns give 7" dist.or 14" eng. at 12"vac, have to check vac. in gear don,t know what it is
soup
yes to thesals it does smell rich
well if it smells rich then that can cause bogging down on the accelleration too, you flood the cylinders... you might just have to lean it out a little bit
hey i have a just rebuilt 355 and took it for a spin and did ok i checked the #1 plug and it was firing but very black what does this mean
hey denny vac is 14.5 - 15 in gear, put accellerator pump linkage back to middle position on edlebrock ,less squirt , seems to of helped on take off ,but still smells rich at idle, might have change jets and rods ?
idle speed out of gear 1000 rpm , in gear is 725 -750 rpm
hit it right on the note denny...
base timing set with vac. disconnected 650 rpm , idle mixture was set at 1000rpm
okay went out set timing at 10 and set carb. mixture at 550 rpm , all i get is black smoke when i rev it up,rev it up slow or fast black smoke,doesn,t seem to be flooding,idle steady, no excess fuel in carb (throat),no leakage or dripping of gas, float level too high or need jet change ? fuel pump is 5.5 psi
new edlebrock 1406 ?
Hi Guys, I am new here, but read the forum alot, great info here. I did notice above soup said he had the vac. advance hooked to the intake. That would be full vac. and timing at idle wouldn't it? Which would change all idle characteristics at idle. Shouldn't it be on ported vac. at carb?
playing on the street, and i just put vac advance back on ported, going to try it ,
