Puff the magic twin choke...HELP!!
Pinto 1600, twin choke webbers..
Fitted new battery and have now got a spark :-)
Added fuel and started cranking the engine over to get it to draw fuel into the filter...
The filter filled up (filter is just before the carbs) and the engine contintued to crank...
After about a second there was a large semi pop/puff sound and a large cloud of vaporised fuel came out of the top of the carb in a nuclear style
mushroom cloud...
There is a teeny bit of this smoke/fuel stuff comming out of the zorst, but most of it puffs out of the carb....it does it every time I try and crank
the engine!
Does it have something to do with too much fuel pressure? Or do I have something drastically wrong like the cambelt in the wrong place. etc?
Basically...help me..im worried I have done something wrong now!

I had the same nuclear experience the first time I tried to start my Pinto with twin 40's.......
My cause was the plug leads were wrong.
Cheers,

I have the HT leads in 1-3-4-2 configuration going clockwise around the dizzy...
I did think that the cambelt was 180 degrees out as well...in my mind its the most logical reason.....
Does this look right with regards positioning the cambelt?
The lower pulley is ligned up on the fat mark
and the upper one has the pointer thing on the back of the pulley at the bottom?

Much simpler to fix than that just swap the plug leads --- 3 and 2 1 and 4.
ISTR Like all other old Ford engines the Pinto is a 1243 firing order but with a clockwise rotation distributor.

this was my first though, this would mean the cylinders firing whilst the inlet valve is open, causing the puff of smoke you see?

Just so I get this right...
"Much simpler to fix than that just swap the plug leads --- 3 and 2 1 and 4"
The current setup is 1342 clockwise....Am I right in thinking that you are suggesting I try 4213 clockwise?

OOh...we have blue flames comming from the exhaust and carb now...
Something has to be monumentally wrong somewhere

Not really, I'm sure everyones experienced this at some stage with plug leads on back to front, or the timing miles out. How have you set the
timing anyway?

According to my Haynes manual for 2.0 Granada, the firing order is definately 1-3-4-2. Would assume this is the same for all Pinto's.

It has been so long (8 months) since I had the engine running last that I cant remeber if I loosened the bolts on the dizzy or not...I dont think I
did so it should still be the same settings as before!
So basically, the timing could be miles out..i dont know....
Is there a basic way to get the timing roughly correct so I can get the engine to idle so I can time it properly with a strobe?
I dont mind the blue flames from the exhaust...they look quite cool...but I dont like the idea of hot flames comming out of a carb full off fuel...its
a recipe for an expensive explosion..

What sort of ignition has it got, points or electronic?
If points then the first thing to do is to set the correct points gap.
Then wiring a test lamp across the coil will let you know when the points have opened, you simply turn the crank until the appropriate timing marks
line up (not sure what offical timing is for the Pinto, but something like 5 degress BTDC should be safe), and then rotate the distributor until the
points are just opening, at which time the test lamp will go out. Make sure the points are just opening rather than just closing!
If it's electronic then you will just have to do it by eye. Take the distributor cap off, set the crank to correct timing marks and turn the
distributor until the four metal "prongs" on the rotating part of the distributor line up with the static ones on the outside.
Once you have the enigne running you should use a strobe light to set the timing accurately.

Yup...silly me! The camshaft was 180 degrees out...
I sorted that and also reset the timing on the electornic dizzy to 6 degrees BTDC...
It now idles...rougher than abadgers gonads, but atleast I can get it warm now and get a strobe on it to get it running just right!
Chears for your help guys...most apreciated!

How did you get cam 180 degrees out? I have just had the pulley and backing plate off mine and it only goes back one way . . .doesn't it?

Quite easy, you just fit the cam belt with the cam rotated 180 degress out, you don't have to physicaly turn the pulley with respect to the cam.

still a bit confused, the indicator on the pulley back plate points at the dot on the block, surely this has to be right if the crank pulley is at
TDC?

I must have been having a bad day when I put the cambelt on...
I swear I aligned the cam pulley with the pointer at the bottom pointing at the dot and the crankshaft pulley at the bottom pointing at the large
timing mark...
but evidentally the garage gremlins got in there and changed things around...
Its silly mistakes like that that just make me so annoyed!..
But im glad its sorted, just hope I didnt damage anyhting

One further turn of the engine would have realigned the cam timing marks . Piston no1 would have been at TDC BUT it sounds very much like the
distributor timing was badly out.
