[Radius Arm Dimensions GT6 Early Mk3]

but its made adjustable soyou can get the correct rear toe in  

having a preset length is just a rough staring point 

having a preset dimension is a hang over from production who never in any manufacturer like to have to adjust anything

so preset lengths were often devised to save any on line adjustments during production 

i remember on assy they set the steering box and drag links on 8x4 before they dropped the engine and cab on  ...caused hopeless straight ahead headaches

and needed to induce a corrective error to correct it when cabs was dropped on.

set the headlamps wthout locking the cab down  good for low flying aircraft 

  the manufacturers were full of these daft tricks 

gear remotes are another needs to be set to suit but they always wanted pre set then fight the pudding and stick as nowt lined up 

Grrrrr

well done Colin   never give up

bit of vaseline works well

and you mentioned ptfe tape      its not good on petrol as its a byproduct and many find it dissolves in petrol

the alloy washers under the float needle will be fine fitted dry 

pete

[Clutch Budgie Squeak!]

sounds a good plan 

Pete

[Fuel spill]

they are quite dedicated 0 rings  yes they can be escape artists , most would buy kits from Burlen

if you buy a online or Aldi box of hundreds of sizes none will fit 

you really didnt need to remove the jet hsg to release the float chamber  it just slips over its  0 ring 

pleased the floats right way up  did you check the 18mm height to the base dimension ??

Pete

[Fuel spill]

the spec is normally around the 2.5psi     

so at 9 you will certainly overtake the float and valve 

doesnt surprise me there have been so many reporting new pumps being silly high pressures 

down to eastern promise copies with no regard to any specification 

i guess if you can swap the spring from the  old unit .

Pete

[Fuel spill]

as a trial  cut  some packing   gasket from an cornflake packet or similar 

anyone you can borrow a low pressure gauge from ????

rubber sliver pests wont get in the float bowl they hide in the supply pipe and float about in the flow and 

find their way into the back of the needle valves   small orifice.

crafty little sods ,cause havoc  

if the pump looks newish then excess pressure are a well known headache 

Pete

[Fuel spill]

Doug mentions upside down floats    yes 

if the float has two valve operating arms they can be fitted upside down 

there are pictures in the buckeye site to show these and which way up they  should fit 

Pete

[Fuel spill]

on the side under the air piston diahragm casting is a lifting pin ,has a small return spring  on it 

you need filters on for this test

while idling you carefully raise the pin till it just feel it touch the piston 

then raise it 2mm

if there is a hint of increase idle its rich

if it faulters a little  its lean 

if nothing happens its about right

do not expect any radical change  more like a 50 rpm shift up or down 

if you yank the pin up fully it will just stall   so its a touchy feely job

as Jonny says mixture adjustment and settings have no effect on fuel levels and flooding

[Recommendations for Tyre replacement intervals]

at last nights pub meet it was divulged that on checking his  Stags boot out to tidy up too many spares found the spare wheel 

it was 29 years old .......it will get replaced 

so dont ignore the life expiry of your spare , yes it will get you home but these need some consideration

and age respect(of the tyre!!)    if used in emergency 

Pete

[Fuel spill]

use of sealer on 0 rings never works well 

i suppose maybe blue hylomar might help as it tends to stay soft 

Pete

[Fuel spill]

stick the plain end of a 5/16" drill up the hose or use a bolt with a shank 

Pete

[Fuel spill]

if the needle valve was in trouble then fuel will overflow from the breather port in the front air filter face

if leaks are from below then its chamber  gasket(there are a good few variants of this  get the wrong one and you leak 

most kits have about 5 variants included    often corners are the change in shapes .

any leaks from the brass jet holder or the adjuster are down to failed 0 rings 

Pete

[Any pointers on this TR4 engine (video)]

heck i get the blame for everything    Ha !!

then if you get each cyl on its compression stroke TDC you can set both inlet and exhaust on each cylinder 

one at a time  saves turning the engine so much .

it will run fine with a big gap but clatter , a tight gap will upset the running /lumpy idle 

a zero gap will cause a full misfire as the valve cant close fully 

Pete

[Any pointers on this TR4 engine (video)]

air piston is located witha tag on the case and groove in the piston so  ...No  

but you could get into trouble with a biased needle set up 

went to a spitty in trouble and the needle sat in the jet when the piston raised  ,  just been left loose 

but not easy to see (well with varifocals and false teeth  ha !)

[Any pointers on this TR4 engine (video)]

we havnt discussed fueling with the dreaded rubber slivers blocking a float needle valve created by fitting nastybrubber hose over metal pipes

and on SU its worth also look under the jet tube spiral wrap to see if the plastic tube has a hidden kink.

and yes  Dougs rule of 9 works well 

the vac tube to the dizzy has no effect on running it advances at cruising throttles as its just an economy device .

but if the spring in the vac diaphragm has failed  ti will not return the base plate to any fixed position 

check with short pipe and suck  and watch !!!

 

[Any pointers on this TR4 engine (video)]

you only need a couple of tight/ zero gapped tappets to really upset things 

Pete

 

[Any pointers on this TR4 engine (video)]

i suggest over advanced and in need of a compression test to start with

check the dizzy has no wear side float on the points cam shaft 

does it have a spurious electronic unit fitted ???

tappet gaps  been checked ???

[Follow WSM Suspension and Steering data for suspension set up or not?]

thats the idea     4 studs on a swing spring box   6 studs on a fixed spring 

so yes leave   2 stud in and slot the packer holes to slide it under the spring box on your swinger.

drop the spring box back and fit the other two studs  then  torque the nuts 

Pete

[Follow WSM Suspension and Steering data for suspension set up or not?]

you could leave the rear set of studs in place   and slot the  rear packer holes 

the packer doesnt need the studs for location the packer is located in the diff case by the spring location 

pete

[Follow WSM Suspension and Steering data for suspension set up or not?]

yes let the spring rise and remove the studs   they are 3/8" and unf threaded   nothing special 

Pete

[Fuel spill]

if its a glass top or a metal cap just remove and clean the cmaber inside ,wash the gauze filter  replace top and re prime with the lever f it has one 

Pete

[Compression test]

and always check your tappet clearances before any comp test , small errors will produce a variation in your result
