Spyda's Mk1

[Peter Jones]

That'll run a stock carb. no problems.

I have a big plastic disposable filter in between the tank and the pump and then a servicable glass filter just before the carbs. Each carb also has it's own built in filter.

Thanks Pete

Let us know how ya go with the replacement dissy and new pump spyda good luck on it

[Spyda]

Looking at buying one of them soon, the 4070 model i think, rated at 5psi and 72gph.
Will this be suitable for a stock carby on a 1800 (single throat solex) for a couple of months till i go a weber setup.

Also did you guys put a filter between tank and pump, read if you don't it can kill pump quicker.

I just looked in to it a bit closer and mine is a 4070, 72gph and 4-6psi rating so I think its the same pump as Pete's.
I picked it up from VPW in epping for $129.

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?

[Water Boy]

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.

The gf got this done:

That's awesome, but does it help your car go broom-broom?

Haha, good luck riding that to SEDF.

Ok so bad news, car doesn't work. Won't run and wont start and it can get ****ed.

Got the res and tip put on at the exhaust shop and then spent 4hrs trying to get it to start, got a wheel alignment and sloooowly drove it home where it broke down 5min from home and i spent another 2hrs tryin to get it running again. Funny thing was it drove without issue to the exhaust place.

A few people suggested the dizzy is stuffed and its getting to much fuel with the ****ty fuel pump so today i bought a 5psi Carter rotary vane pump, almost the same as what Pete Jones runs on his race car but from what i understand his has a higher pressure. I mounted it the same way he did. The pump is a lot less noisy than the other one, just a slight hum rather then DAK DAK DAK DAK!

Pete was also kind enough to lend me a working dizzy that i will pick up tomorrow. Hopefully it does the trick and i can get this box to SEDF at least.

I hate being a shiz kent at this!!

This is how Pete mounted his:

hey dude in regards to the pump im guessing its possible to do a similar mounting with the original cordoba style pumps??? mines just the square type at least i think it was the factory one. Was thinking about mounting mine on the underside towards the front but that pic makes me think the back perhaps.
