Spyda's Mk1

[Spyda]

Picked up the dizzy from pete today and installed it.
The car ran for about 5min perfectly, idled smooth, reved smooth, turned off without turning the motor backwards, perfect! Then once it warmed up it all went to shiz.
I tested the ignition coil and it was reading like 5mega ohm on the secondary coil, once it cooled down it was back to normal about 15k ohm so i figured it was stuffed and went out and bought a brand new coil.
I installed that and the car runs and revs but like it used to. Idle is rough and wont idle below 1.5k. I still cant get close to the timing mark but I assume it will drive.

The weather was getting bad and i had enough for today so ill test drive it tomorrow.

might sound weird, but double check timing belt and all timing marks again.

My first 1.8l did same thing as yours, turns out cam was 1 tooth out.. it ran and revved fined... but it would hold idle and when it did it was 1400rpm
It it hydraulic lifter? maybe one is sticking and not getting valve open fully.

Might just be something very small

Cheers mate, ive checked timing 100 times but i dunno how to get the teeth 100% right on the cam as all it says its the mark has to line up with the rocker cover.
Its a hydraulic head off a mk2 gti, ill check the valves if it doesnt drive tomorrow.

If it drives ok then i will take it to a pro next week and get it all done properly, im sick of pretending like i know what im doing.
Any recomendations?

Have you got the fuel presure regulator set at 6psi?

Also needle and seat? Main jet blocked?

When comes off chock there is a blockage?

[GRN_VAGN]

yeah i got a 1.8L from a mk3. the timing for cam is a bit easier as it has a arrow on a plastic bit to line up with

Not sure whats wrong, mine was same cold or hot..

Was told i dont need a FPR, i was also told the carbie was fine. Im not using the choke because when i did it got hot and at one point melted a bit.

Also forgot to mention that it runs the same hot or cold now.

At the moment i just want to get it to the show, after that im giving it to a pro because im done stuffing around with it. It was ok giving it a go and learning a few things along the way but its getting to the point where i dont have the time and pacients as well as the knowledge. I also need a car to drive around as dads merc needs work so we are sharing the polo.
