My boss is getting his RRC back after it being in the garage. It needed a fair amount of work and he's only just bought it.
Finally it's ready and the mechanic said he set the timing up. Instead of being the normal 6 deg BTDC +-1, he said it would only run at 20 deg BTDC.

Runs fine like that - any ideas? It doesn't sound like a good thing.

The previous owner said it had had an engine rebuild.

Where's the timing well on an RRC?

ironhorse · Oct 23, 2007

Did he take the distributor out

Irohorse is just fishin' now!

SuperPete
DO YOU KNOW ANYTHING ABOUT TIMING, if you do why don't you share it with us, if you did you would know why I asked the question

I don't think the dizzy was removed completely by the garage - god only knows what the previous owner did when he rebuilt the engine.

It's a 3.5efi (an 86')

I spoke to him about it today and it's 18 degrees BTDC - seems to run fine but how the hell can it be that far out?

Best leave it there Ironhorse since I don't know you and you don't know me and it's impolite to shout in public.

After removing the distributor, if the engine is then turned the location point for the distributor has also moved, when relocating the distributor the engine must be on its timing marks before the distributor is inserted into its correct place. I have in the past found the distributor has not been correctly inserted and who ever placed the distributor in the engine has then compensated by turning the distributor to get the engine to run, it maybe this is your answer

I see what you mean - the dizzy is keyed to only fit in at a couple of points I guess. You think it's a bad thing to leave it like that? Obviously something isn't right but if it's running ok?...

ironhorse · Oct 24, 2007

It should be ok

merrick · Oct 24, 2007

a strobe light does not look at where the disie is it checks the spark in relation to the position of the crank it does not matter where the disie is there is a possibility the cam is misstimed

slob · Oct 24, 2007

yer really think the cam is mistimed if it running fine?

merrick · Oct 24, 2007

one tooth out and most times you think its runniig ok but it will require different ign timming

ironhorse · Oct 24, 2007

In order to get your position on the crank you must have the dizzy in the correct position, alter the dizzy you alter the relation to the crank

rojbarker · Oct 25, 2007

Thanks ironhorse, I'll tell him to carry on regardless then!

?????????? tou can put the dissie in any where you just have move your firing round to correspond and the strobe will still give you the same readingi ie when its firing inrelation to tdc no 1 pot

Stupid question time, but I'm good at them. Are you sure you're hooked up to No.1 plug lead and not No.2 (wrong bank). I did that years ago on an merkin V8, biy did I look a tw*t when I realised why I couldn't get the timing right.

rojbarker · Oct 26, 2007

The guy at the garage sounded pretty competent from what I've heard him say so it's unlikely he did that - but you never know!

merrick · Oct 26, 2007

if hooked onto wrong plug lead it would be minimum 45 degrees out[8x45 =360]thats if its next in firing order
