pulled the trike out to swill the engine out while the rear core plug is out, lots of white crystal stuff and a little brownish water came out. had it running while hose pipe shoved in top of rad.  went to put the core plug in and it allmost fell in, had a look today and waters freely dripping out. any ideas, do you hammer the core plug in the center of the dome to expand it,? last time i did one was a beagle  ha van.

Thats there to suck blowby gases out of the sump on a mini - not sure if this carb is original reliant or not?
Connect it to the rocker cover and fit a breather type filler.

Problem with the fuel pouring out ,
I take it that the fuel hose is attached to the left hand pipe on the floatbowl lid and that the overflow hose is open to atmosphere ?
Photo info on hose positions at ;
https://sites.google.com/site/fifersrelianthintstips/carb-stuff/carb-maintenance/su-carb-floatbowl-info
.
Is there a gasket on the float bowl lid ?
The nylon needle in the floatbowl might be faulty and not shutting off ?
.
The float might be punctured ?
.

.
Set the mixture as per ;
https://sites.google.com/site/fifersrelianthintstips/carb-stuff/carb-maintenance/carb-only-runs-with-the-choke-out
.
The tube at the side of the carb needs to have a hose connected to it and then connected to the rocker cover breather cap .

it is a original reliant, [i think] . will connect it up.
theres a screw missing from the top of float bowl which may make it not seal fifer.  does the carb rely on pressure from the rocker to run right.?

i used to blank the breather pipe that comes out the side of the carb and went to the rocker cover  then let the rocker cover breath to the atmospere via a short downward pionting tube

The tube at the side of the carb must be sealed .
It can be blanked off with a piece of hose and a bolt to blank the hose but , if you do that and leave the rocker cover breather open to atmosphere , the engine draws colder air in when you switch the engine off .
This can often cause condensation and gunge building up in the rocker cover especially if the vehicle is used for short journeys or is not allowed to get up to full working temperature ..
With the hose connected from the side of the carb from the rocker cover the carb sucks the vented air from the crankcase which is pushed up into the rocker cover to scavenge the sump .
.
Regarding the floatbowl , remove the lid complete with float and test for a punctured float and that the float shuts of the needle as per ;
.
https://sites.google.com/site/fifersrelianthintstips/carb-stuff/carb-maintenance/carb-floatbowl-faults
.
Check the float height as per

.
Did you put oil in the top of the carb dashpot ?
.
Also , if you get technical , I have made needle comparisons  so that some idea of where the needle points are weaker or richer at different throttle openings and can often be helpfull if used on trikes which obviously have varied exhaust systems .

When you clouted the convex centre of the core plug to fit it  is the core plug centre now concave ?
There is an optimum point where the outside of the core plug has spread to the maximum .
After that point the centre becomes concave and starts to pull the outside in again therefore it does not seal .
Fortunately I have never had a cylinder head worn so bad that I have had to use a sealant but lots of owners of various makes of vehicles have used it with success .
