Distributer troubles.

Bungers · Post by **Bungers** » Tue Jan 31, 2012 6:48 pm

Big stuff up here guys.

Pulled off my dizzy, put it back on, and my recently acquired 88 brumby is coughing and spluttering all over the place.

So at the time i thought maybe i broke the dizzy as i took it off, so i pulled the dizzy off my other 88 Brumby thats getting restoed, and put it on the 1st brumby and behold same thing. LOL.

So anyways i heard theres a proper procedure in putting a dizzy back on, something to do with timing marks on the flywheel.

Has anyone seen a "how to" or a link to one? Or does anyone know how to solve the problem?

Cheers Pierre

Yes you can't just put the dizzy back on in any old fashion, the gear on the dizzy needs to be in exactly the right tooth of the gear on the crankshaft.

I think what I did last time was pull the spark plugs out and the rubber plug out of the inspection hole on flywheel housing. Turn the engine over by hand until the 0 mark appears and lines up with the pointer (I'm not sure if you have to put the pointer at -8 here, someone will confirm/deny) Then on the dizzy point the rotor at where the #1 lead goes on the dizzy cap. You have to then turn the rotor a tiny bit clockwise (I think it's clockwise) and slide the dizzy into the hole on the block. The slight clockwise turn is because when the helical gear on the dizzy slides into the teeth on the crankshaft it will turn anticlockwise slightly and would usually put your timing 1 tooth out (if you turn it slightly before it will still turn anticlockwise but you'll be on the right tooth)

Then set your timing as normal with a timing light.

Yes to all the above.

Need to be on number one compression.

Finger over no.1 plug hole while turning the motor, stop at about 10 BTDC.

Drop in dizzy, etc as above.

Ok, the car now starts, and idles nice, but once its warm it stalls. It wont idle unless i give i use the throttle. On close inspection i found some hoses that were either plugged with a screw or were just going to nowhere. Can anyone tell me where these hoses are supposed to go?

Oh and I have changed the oil, filter, air filter, fuel filter, sparkplugs and sprayed carby cleaner. I have a dizzy rotor, dizzy cap, ignition coil, and ignition leads on the way from the US. (As well as a fuel tank cap, water pump, rear shocks, spark plugs, and lug studs for the 6 stud conversion.)

Looks like your engine has alot more anti pollution gear than mine so I can't tell what those hoses do either!

But I can see at least one of them comes directly off of the manifold, I'd say these are vacuum hoses and if they're disconnected they will let un-metered air into the engine and affect the idle/running.

With the engine idling (with the choke on sounds like your only option for this) put your finger over the end of the hoses coming from the manifold to see if there is any vacuum there. If there is then that's a leak, plug the hose for now to see what it does to the idle. If there's more that have vacuum but go nowhere plug them and just see if that's what is causing the stall once warmed up.

Ok the hose in pictures 2 and 4 are meant to join at a "T" and plug into the line in the aircleaner case as seen in pic 4.

That leaves me with the hoses in pics 1 and 3. Both are sucking air when car is on.

Well there's your problem then, you had vacuum leaks all over the place! just plug the hoses in pics 1 and 3 for now until you can find out where they go, this should fix your idle problem or at least stop the car stalling when it's warmed up.

Ok two hoses left.

Ok in the first link, there is a smaller hose that comes off a small tube in the firewall. I think its then connected to the hose coming from the throttle body, (3mm-6mm connector) Then to a Tpiece. But then i dont know where i would connect that tube too? Cab anyone confirm where that piece on the throttle body goes. Its got vacuum, but when i plug it, my car still stalls at idle.

The hose in the second pic, i have absolutely no idea where it goes.

Also need to know if the hose off my dizzy is going to the right place.

Could we have a pic of the firewall where that hose comes out? It could be the vacuum line to the heater/blower actuator thingy under the glovebox. As for the hose in the second pic I couldn't tell you as I don't have that on my manifold.

The hose coming out of the dizzy is the vac advance line for the dizzy, it needs to be connected to a vacuum source or it will cause issues with ignition timing I believe, which would not help your idle problem. On mine it is connected to a T piece which goes to the carb, and then off to a vacuum port on the manifold.

And yes turning that screw clockwise will raise the idle, it just pushes the throttle linkage to open the throttle slightly. I wouldn't adjust that yet until you have the hoses sorted out, namely the vac advance on the dizzy and plug the vacuum leaks.

Cheers mate, the problem im finding is that my other brumby doesnt have all these hoses that this brumby does,cos this brumby has ac, the other doesnt.

My other brumbys engine is the same as yours, distributer line is teed to the carby, this one i think goes to the air cleaner.

I have to disagree with you there; that tin drum it's connected to (vac advance mechanism) has a rubber diaphragm inside which is mechanically connected to something inside the dizzy to alter the timing over different rev ranges, take the cap and rotor off and you will see it. Anyway it needs vacuum to operate. Once you've got your other hoses sorted out and come to using the timing light you disconnect the vac advance line and plug it (the hose not the dizzy

) while you set your timing and replace it when done.

I forgot to disconnect the vac advance line when timing once and the car ran like an absolute pig and would not get above 50 km/h, also stalled after it warmed up like yours does.

and it needs to ported vacuum from somewhere off the carby not directly off the manifold
