Is my dizzy f****d

[Theyellowmex]

So the dizzy in my pinto with the cap off i can twist rotor one way and it springs back which is ok but i can turn it the other way about an inch and it will stay there! Thats not right is it? Its new new off ebay one of those 75 quid electronic non vac ones

Mmmmm. Not sure about the springing back or not in both directions, I don't think it should, but I'm happy to be proved wrong.
But all I would say is I would never have paid, just £75.00 for a new dizzy..

Just far too cheap Im afraid. I know that doesn't necessarilly help you though.

Get what you pay for i know.it only springs back anti clock wise if i turn it clockwise which i think is ok but i can turn it anti clockwise about an inch and will stay there

Springing one way is normal but you shouldn’t be able to turn it in the other direction, is it fully and engaged in the drive gear? Is the rotor arm fully home ? Some more info needed ???

Exactly.. Yea I know what you mean, I'm not sure whether that's right or not tbh. But I don't think it should do that.

I didn't think it was right...

Thanks.il double check tomorrow.been trying to get pinto started in my mex with stage 3 head 285 cam twin 45s.i have had it running very erraticly.now wont fire/start.checked timing over and over tdc on number one on compression stroke 1342 .got spark at plugs.cant even start to set carbs up as wont run.was getting flames and bangs at one point which points to maybe air leak but carbs flooding as well!! Trying to get running so can take it rolling rd.now thinking dizzy prob. Cheers

Is the rotor arm sitting in the top of the distributor shaft fully? I had similar problems starting my newly built Pinto only to find the firing ring for the Accuspark type electronic ignition wasn't letting the rotor arm lock into the top of the dizzy shaft.

Cheers il double check tomoz i think its one of those accuspark electronic types. I do remember the tip of rotor contact was bent up for some reason which i corrected and its still intacked

Sounds to me like a timing issue rather than an air leak, are you sure you haven’t set it up 180deg out? Ie No1 & 4 at tdc but firing on 4??

Are you sure you've answered the right thread Erik?
yellowmex is still only referring to the the dizzy shaft rotating, rather than timing or air leak.


Apologies Erik, just realised you'd replied to post #6

I already tried swapping leads 1 to 4 2 to 3 etc i to think timing prob thats why dizzy concerns me

[Erikmex]

Have you turned engine over by hand or cranked on the starter with dizzy cap off to make sure it’s rotating as it should ?

Turned by hand with cap off thats how set timing
Cheers

Checked rotor this morning befor work a tiny piece had broken off underneath so was not locking in place andwas turning on shaft! I take it that would cause timing issues? Il get new one today and start again

[rallyrob]

Definitley, it'll mean the timing is continously moving.


That happened to mine years ago, it was missing like mad.
I ended up with a bit of insulating tape round the shaft for the rest of the day to hold the rotor arm in place.

Update.swaped rotor also found plug leads wernt connecting fully on cap.up and running now timing at 12degree bftdc.thanks for all input guys been great help

Glad you got it sorted.

The plug leads things is something that popped up on another thread a few days ago too.

Graham had the answer to that one...
