stupid 304 timing why cant i get it right??

[Immortality]

MAYBE if you posted all the relevant facts to begin with we may be able to help you, it's not my job to research facts, it's up to you that YOU give us all the relevant info, so many times on these forums someone asks a question and then eventually after lots of chasing around the facts and asking a million questions the OP gives that one little bit of info that solves the problem.

So you have a chip, maybe try the stock memcal, it should start and idle but I wouldn't drive it but at least you can then rule out the chip being an issue.

What is the CR?

When you say you dialled the cam in, is that 9 links on the timing chain or did you actually put a degree wheel on it and a dial gauge to check lift etc?

How old is the balancer? maybe the outer ring has spun putting the timing out????

No skin of my nose if you get it running or not.

Good luck with it....

BTW, the 286 with 110* LSA I'd suggest that 10:1 is really the minimum CR you want as it has a fair bit of overlap. Did you change the intake manifold? The stock bananas manifold will start to choke the engine at 5500 rpm as the cam is really starting to come on.

the cam was dialed in correctly and the timing gears are roll master double row, cam was dialled in at 0
,
and this cam is actually fine with just a complete stock motor, even with stock comp, but just so it cleared my heads r shaved, ported,polished, oversized double springs, match port exhaust job, yella terra roller rockers,and head specialist made heads specific to suit a cam like this. anti pump ups, billet rods, upgraded tb, cai with custom growler setup, pacemakers to 3' with hi flows and my manifold has been bored and drilled out for that little extra "why not factor"

as for the balancer not sure my mate gave me a pro lightweight from his old vn ss as he upgraded the motor

Pull your spark plugs out and dry them. If it has been cranking a lot, the fuel would have soaked the plugs and they won't spark.

When you put the distributor in, you obviously know to turn the rotor about 40 degrees anti clockwise to allow for the rotation when the gears mesh? You align the roll pin on the drive gear with drain hole on the dizzy shaft and when it slots in, it rotates to the correct position. To double check if the dizzy is 180 deg out, just make sure number one lead is at the back of the dizzy, not the front. Early 308's are at the front, the 304 is at the back.

I assume from you comments that you have already had it running and tuned since fitting the cam? If so, we can rule out cam timing and compression issues out as a source of your problems.

I would first pull out the plugs and see if they are wet with fuel or not. If wet they might just need a clean and dry, if they are dry it might be a fuel related issue and not timing at all. Earth a plug while it is out and see if it is giving a good strong blue spark. Back to basics, fuel? spark? then timing.

yeah for sure, what i did also is put a little black dot on housing where gudgeon pin is when rotor is spot on for when i go to line shaft up, so before i put in i line up with my personal mark and then as it drops in it flicks back to be perfectly on the correct oe reference poin, but for short (lmao) exactly what u said is what i have done and number 1 lead is at the back just to the right of centre line, im sure its the one closest to the dizzy cap clip to be presise i think...

come to think of it, using a clock as a reference my dizzy ends up sitting in the motor as follows
cylinder 1 and lead at roughly 1 o'clock

after noticing plugs soaked, i removed all then cranked motor a few times to 1, to double check oil pressure was definetly hi enough 2 to rid cylinders of any excess carbon and fuel deposits then purchased bosch top notch hi irridium plugs .... it that doesnt get her roaring, i dont know what will

 

[greasemonkey24]

just noticed its not a good strong blue spark its yellow goldish, so yet again another coil on its way from veals autos,

When you place the leads on the distributor as per the plan detailed earlier, the clip holding the distributor cap on needs to be between the number 1 and 2 lead positions and likewise on the other side of the distributor the clip needs to be between the number 4 and 5 lead positions. Even if you follow the plan it's easy to get all the leads in the correct positions next to each other but have them all one position out. If you have every thing OK, loosen off the distributor bolt and get someone to crank the engine while you slowly rotate the distributor 5-15 degrees in either direction and see if you can get the engine to fire.

yeah thats roughly where the clips sit on both ends, i downloaded a diagram of how the leads are meant to sit aswell, u know how the all intertwine correctly not just pushed on any way, i think ive sourced the problem as my headlight main fluse blew somwhere along the line and i researched a few wiring diagrams and that is connected down the line into theft deterrent switch, ignition and kety reciever so i might look into that alittle further but if that isnt it im guessing its this

on right hand bank (passenger side) there is an earth that bolts to head, off this wire is another earth that splits into 2, one to the 02 sensor and the other i have no idea but using test light from batt+ to main earth it lights up brightly when connected to other black earth wire its dull so trying to source a diagram on where this connoects to from rear wiring loom???????

wires may stop it running but will not stop it starting - if you have spark and fuel as you say you do
