fuel regulater

I have just fitted a second hand recon and it came with a fuel regulater?
The van feels like it needs more power and it has been playing up. I think it is down to fuel starvation. will the regulater slow the fuel flow down enough to starve the carbs of fuel ?

Bri,,,,,,,,it is always a good idea to start your posts with type of engine and CC you are running so we can help you with any problems.

My guess is you have fitted a replacment 2.1 motor complete with the injection system,,,,,, as these are generally the only ones fitted with a fuel regulator from the factory.

To answer your question,,,,,,,,,Yes it is possible someone has been buggering about with your regulator, which will cause fuel starvation if it isnt set correctly.

have you been to a rolling road?
if not the chances are its bugger all to do with the fuel regulator and more to do with the fact your carbs need jetting.
whatever the "suppliers" say the jets these things come with are never right. if it is running lean you run the risk of doing it some serious damage. get it to a rolling road asap.

I havent been on a rolling road yet, i have only fit this engine last weekend. I was driving yesterday when it felt like it was only fiering on 2 for a short time then cutting back in again. It realy did sound like fuel starvation.
I am even unsure if it will make it to a rolling road the way it is, do i take off the regulater and see if it's any better?

i was running a pair of dual twin choke delortos on my cu motor with the stock pump and no pressure reg. it was bob on.
even if this cures it please get it seen to or chances are you will fry the motor.

What fuel pump have you got... ??
Depending on what pump you are using, you may need the regulator and adjust it.. as the carbs will flood from too much pressure...

If using the std mech pump, you may find under full throttle it wont keep up too.. so thats why an electric pump would be used.. then you need to regulate the pressure depending on pump spec...

A good rolling road is worth it...

Oh... I cant quite see in the pic but make sure you fit an engine to body seal or you WILL cook the engine..... :wink:

my old Aircooled ran the stock pump with dual twin choke 36mm delortos with no probs with fuel supply issues at all. the prob with the aicooled fuel pump is that you just cant get a replacement!!!

I am using the std mech pump and i have just come back from a 60mile trip. I have got to say the engine is running realy well with no holding back.
As for the (engine to body seal) do you mean the seal that goes on the outside of the tinware?

yes, the bit that keeps the hot air from the cold air... you cant cool an engine with hot air... nos as much of a problem in the winter, but come summer.....
