Re: Early vs late DG Engine

I had a catastrophic failure of the cooling system on the motor way :-(  The metal flange on the rear of the engine corroded completely resulting in rapid loss of coolant. I therefore don't trust the rest of the system after forking out for a new engine and some of it is visibly tired, so will be l...

Re: Mobile mechanic or club member to set up dizzy/timing on 2.0 Aircooled t3

On a petrol I'd suggest giving it a go - £25 for a timing light and you're away. Its only a case of lining up up some marks whilst twiddling the distributor. 

Happy to write more detailed advice if you fancy a go?

Re: Early vs late DG Engine

You say you cooked the last engine - is that a result of the cooling system, or some other error? Assuming the cooling system worked before and wasn't the reason you are installing a new engine, I personally would unbolt the old block and bolt the new one in (or get your mechanic to do it!) Asking y...

Re: Engine oil light staying on

Excellent news.

I would sort out the dipstick though so you have a way of accurately checking the oil!

I'd second this - I have one, just bolted on and that was that. Sounds nice too. 

As below though, snapped studs are a big issue if they happen, so a lot of people don't want to touch it or charge silly money.

Re: Engine oil light staying on

Switch is normally closed - i.e. the pressure pushes apart the contacts and turns the light off.  Quick check, unplug the wire from the switch, light should go off. If light stays on you have issues with the wiring.  If it goes off with wire unplugged it is either a faulty switch, or you actually ha...

Re: Stumble, stall under throttle

If that hole goes all the way through into the carb it might not be all of the answer, but it’s definitely contributing!!

Try sticking something over it and see what happens - it’s on the engine side of the carb so will be drawing in unmetered air and giving you lean conditions.

Re: Stumble, stall under throttle

Glad to hear carb is working as expected.

Coil sounds like it’s worth a punt. What are the connections like as well.

Did you do new plugs with the new HT leads, either way are they correctly gapped?

Re: Fast idle when hot

The long screw just props open the throttle - you should see it rests on a little notch on a plate on the shaft. There is no voodoo or black magic like some screws on carbs, its mechanical. 

Sounds like your screw might have stripped - does it visibly change length as you screw it in/out?

Re: Stumble, stall under throttle

Could be fuelling related. Two things to check to start with: 1) you don’t have any air leaks - spray carb cleaner or similar around all the various manifold joints, and also around the throttle spindles. Any change in engine speed indicates a leak that needs fixing. 2) check accelerator pumps on th...

Re: Engine oil light staying on

Am I reading this correctly, your oil light was flashing, and when you checked you needed to add 1.5L to bring it back up to (slightly more than) full. What were you doing when the oil light came on - i.e. where you driving? How quickly did you loose the 1L of oil below the maximum? What oil have yo...

Re: Aircooled Knock under load.

It’s pretty common to develop bottom end issues after a full top end refresh. I watched a great video (which I can’t find again) of an American changing the big end bearing shells. It went like this: Remove heads, withdraw barrels but leave them just over the piston so the rings stay compressed. Thi...

Re: Brake master cylinder

For any future searchers, the answer was there was no need to bleed the clutch - just clamped off the big flexible braided feed hose, changed the cylinder, refilled with fluid and unclamped hose.

Re: Persistent rocker cover oil leak

Not all covers are equal, they can (especially aftermarket ones) not seal that well. Not all cork seals are equal either, espocially if they have been stored badly - worth checking they actually sit in the covers nicely.  As above though, first thing is to make sure there is decent tension - if you ...

Brake master cylinder

Hello, I believe my master cylinder has failed, as the almost new fluid has turned black and the pedal is unpredictable (occasionally goes to floor, will sometimes drop under sustained pressure, but mostly ok). Got a new one on order. For fitting, if I (gently) clamp the braided clutch master feed h...
