I'm currently running, a 2276 with dual dells and the ignition system is a 09 distributor with the Petronix ignitor II with a flame thrower coil. now my problem is, after about a day of running, one or maybe two spark plugs will not fire anymore. i am thinking of switching to a hotter multi spark ignition, maybe a MSD setup. what do you guys think? or is there a better ignition? How is the compu-fire DIS-IX setup? A friend of mine has that setup, and he burnt up a coil, and it put him out for the whole weekend, are these any good?

The setup that you have now should be fine, are you just fouling out plugs? if you are maybe you are running too rich and fouling them out. Pipedope has a Petronix distributor with a flamethrower coilpack and never have any problems, still running the same set of plugs since he put the system on and it has been over a year. I am running a MSD distributor, 6AL Digital ignition box and HVC coilpack and no problems there either. What plugs are you running?

When you pull the plug out that quit firing, what does it look like?

A better ignition will just mask a jetting issue.
You will foul plugs with those too but might take a bit longer.

Which two plugs?
Same every plug(s) every time?

Im gonna run to summit today, and buy that MSD setup. I figure, if it dont help the problem, it might give me a little more performance. but i am gonna order some smaller jets and give that a try. weird thing is, about four years ago, when i built this motor, before i ran it, i took it to Jim's custoum VW and had Jim jet the carborators for me. it ran good, the plugs were tan colored, and inside the exhaust was a silverish color. it ran like that for a couple of years, as a matter of fact, i didnt change the plugs for about 2 1/2 years. and now, everything is running rich, and im fouling plugs. its mainly number one plug. but all four, are comming out flat black.

Jets will wear out over time and become larger. It usually takes a long time but you never know. Have you checked your fuel pressure? That might be the problem and not the carbs.

I never thought that jets will wear. do you think that i should go smaller or get new ones thats the same size? what feul pressure are dells supposed to run? i thought that they were supposed to be three pounds. I bought the rotary feul pump from CB performance. it was supposed to be designed for three pounds. im not running a regulator. maybe i should put a gage on there and check. oh, i went to summit today and bought the MSD pro billit distributor. and guess what, its about 75% plastic. the only part that is aluminum is the stem that sticks in the motor. thats what you get for 240 bucks.

Dont let that 75% "plastic" bother you . Those dizzys & 6AL ignition systems are the shiznit!! Motor will lug better, accelerate smoother and wind up better.

Just be sure to blow it out after you wash your buggy or get caught in a hard rain, then spray some silicone (like the waterproofing stuff for work boots) on it after you put the cap back on.
It will get some rust on the magnets no matter what you do, but as long as you dont let it get excessive, it creates no problems.

Procomp makes a knock off system that seems to be working great on Yankee's buggy. Gustograber has one, too, but dont think he's using it yet. Coil, billet dizzy w/ cap and CD ignition box all for $279. Plug wires extra. Have to buy different springs and bushing seperately also. He just bought kit from MSD ($15) at local hotrod shop, they worked fine. He just put it on this year, so dont really know about long term reliability yet.

Dont forget to regap your plugs. I run mine at .065" w/ 13:1+ comp. And cut the two little wires inside the black plug on the side of the MSD box. MSD told me the built in Soft-touch Rev limiter wont work correctly unless you snip the red and blue wires in there, on a 4 cylinder application.

If your buggy ran really well at one time with those jets I really doubt your problem is a jetting issue. I feel it may be fuel pressure OR it might be as simple as changing your needle and seat valves. When they wear out the motor will flood itself and foul plugs. Lots of folks overlook these. Remember, they are the key part that turns the fuel flow on and off!

If the seats are bad, what are the chances of both of them going at the same time? I think before I tear into the carbs, I'll get a fuel pressure gage and check my pressure. Now if I need a regulator, what is a good regulator that goes down to about 3 pounds? I was going to buy the MSD offroad ignition box, but those things are $250, then you have to buy the rev limiter box, which is another $150. Then you have to buy the rev limiter chips and a kit which is $70. So what I ended up with was a Summit offroad ignition box, it has the rev limiter built in. These are digital, not analog, like the MSD box. The price was still about $250. Where is a good place to put the ignition boxes? How much water and mud can thiese things handle? The instructions said they are completely sealed in appoxy and not to put it into another box so that way they can dry out. But the rev limiter dials are kind of exposed. I'm thinking about putting it under my roof. But I don't like it being so close to my head. Where do you guys put them?

Mine is on my rear deck, inside a plastic cordless drill box I screwed down to the diamond plate. It doesnt seal real tight and I open it up to dry out after I wash it. It was out in the open on my old buggy and got hosed down often. About 90% of the other buggies I've seen have them mounted right out in the open. And most I ride with use the 6AL which isnt even "offroad" rated (analog, built in rev limiter). They are very hardy and I know guys that have had the same 6AL box for years. I'd imagine the offroad ones, like you bought, would be affected even less by the elements. I'd definately keep it away from your bean, those boxes are hard! :D (And cheaper than a new skull.)

MSD makes a digital ignition box, it is a Digital 6 Plus and that is what I am running, it has all of the dials on the side of it to adjust your rev limit and other goodies. I mounted mine inside an ammo box, it works perfect for a ignition box, you should get ammo boxes for anywhere for $10-$15 a box depending on the size. It has to work great because how does the military keep their ammo dry?

i took the summit ignition box back to summit and exchanged it for the MSD 6AL. The problem i was having with the summit box was timming, the only way the motor would run good was at 42 degrees, it just really didnt sound right. so since everyone else was using a 6AL i though what the heck,and it timed out real nice at 32 degrees, i used the blue springs and the blue stop on the distribuator, and it sounds real strong now. i rebuilt my carbs, with new float seats and all. i installed a new fuel regulator and gage, and my pump was pumping at 2 1/2 pounds. hopefully we will find out how it runs this weekend.
thanks for your help,
Dave

It runs awesome, that motor never ran so good. it will ideal forever. and the low end power is just like wow. i put a 6,000 rev limiter chip in and man it just goes up there so quick and so smooth. money well spent. if i would have known what it did to the motor, i would have bought it years ago. thanks for all of your help. couldnt have done it without ya'll.

that motor was running so good, it had so much power, that i ripped the first gear out of the 6 rib. i have a couple of phone numbers from you guys. i'm gonna give them a call and figure out what my best options are. i got kinda lucky, my wifes car got smashed up so i went and bought her a brand new cobalt, I put $ 500 down, and I'm using the rest of the money from the insurence to pay for my tranny. the funny part of this is that she agreed to it.
thanks alot,
Dave
