Yikes. Not sure what else to suggest apart from a brand new dizzie. Or new engine...

haha oh sorry..
i was meaning with the old carburettor on it i had the same problem.. then put a brand new carbie on it and new module, sparks, leads, coil and still the same problem

Whats a pre carb?

I have a brand new carb on it someone suggested vac advance sticking but yeah the prob was the same pre carb

That sounds like a carburetor issue mate.

this evening i just fitted brand new sparks, brand new leads, brand new coil, brand new module.. very smooth but still between 10-20mph on the speedo still getting sputtering.. much softer but still there.. i wonder if it's something to do with the ignition wiring or if the dizzy just needs a reco!

Changed the module, spark improved but was still a little poor, replaced plugs with another used but newer set and the spark is quite good.

Well!
I do have a brand new module so no auto elec should be required I'll just remove the little housing and take out the old module and screw the new one in..

ohh ill be interested to know how you go with the new module! mine cost $32 from ebay brand new but had to wait 5 days for the auction to end and then another 3 days for postage so it just arrived at work about an hour ago!

i guess ill replace the module tomorrow sometime before i go (heading away for the weekend) and will see.. i guess the only thing to do re the wiring would be to not route through the ballast resistor and revert some of that temporarily to see how it goes.. I'll have to change the coil mounts over again but still could be a good thing!

you let me know how you go clyons8 and ill let you know tommorrow! hehe

I've said this before and I'll say it again. When you put a 'working' hei style dizzy and coil into a car that was on points, the result is so good, you'll wish it was the first thing you did when you bought the car. I say this because everyone I've helped put hei on their car (old holdens, various valiants, even slants, using a hemi dizzy and bosch module) has said those exact words, almost identically each and every time.

They just kick butt for cold starts and throttle response, fuel efficiency, you name it. They might not make a lot more peak power (unless the rpms are higher to the point the points don't like it) than perfectly adjusted points, but the mid range, the gains across the range, it all adds up.

Cars that used to foul plugs due to hot cams (where racers would previously start the car and warm it up with one set of plugs, then switch in the 'main' set of plugs for the race) are a thing of the past.

Find out what is wrong with it and fix it. About the only argument I could make 'against' it is the cost - if a couple of hundred bucks (for which you could have a new electronic dizzy outright) is too tough on the budget (and I am no millionaire myself either) then ok, stick with points But if the budget will stretch that far, you'll never look back.

The problem is the module.

Mine is a similar unit except it has had the module installed as a separate piece, you can see the scorcher label is actually stuck to a cover plate which I think is where the 'box' or module was installed (as with your dizzie).

I will have a new module in about 3 hours so I will let you know then.

I had the car running sweet, the brakes weren't bled yet so I left it till the next day. When I had the car ready to go it wouldn't even start. I re-did the timing, stripped the carbs, swapped the carbs and checked for vacuum leaks. When I swapped a new coil in early this morning, it was obvious the spark was still very, very week. Should have checked the spark first, however, I did find that some water had found it's way into my carbs so I was kinda glad.

I rang an auto-electrician to get some prices to have a look and he insisted that it was the little black module. He said they fail frequently and I am best to buy a spare to have in the car. The module was priced at $60.00. I could have gotten ti cheaper but want-it-now means bigger bucks.

Why don;t you just take it into an auto electrician and ask that he have a look, otherwise take it straight in and request to have the module replaced. The chances of the actual dizzie failing a fairly remote, all it is is a hall sensor setup and some bearings.
