just read your blog. you have a good eye for carbs. they are my favorite for tunning. the nice thing is they have air by pass screws. if you know whats what with these and have the gear you can have performance and economy. if they are jetted right and set up they are so smooth. yum yum
p.s. i have the gear to set them up sweet.

It's not a problem dude ... I was only pulling your leg, i'm not offended Laughing If I was, you would know about it lol!

Saturday morning you just caught me out as I never meant to drink the quantity of cider that I did on Friday evening drunken

I've tried to do my homework as far as the engine and the components I'm using with it as never really built a performance engine.
Closest I've got in the past is bolting in a 1641cc with progressive Weber!

If you have some knowledge of the Dell 36's, how to set them up & tune them, I would be very interested in learning how it's done please fella Very Happy

PostSubject: Tuning dels   Tue Feb 12, 2008 10:39 pm

Razz Razz Razz Razz do not read if you get bored quick
no worries i can recomend a book or just show you first job is to set the float hight and do the jet calculations
Float hight 12-13mm open and 5-6 mm closed
throttle butterflys need to have a snug 3 thou gap between the ventri wall ( by adjusting the idle screws) A piece of thick writing paper is about 3 thou if you dont have a feeler guage. Also make shure the butterflies close with a snap not all lazy and bunged up.
mixture screws 3 turns out. the carb is a pressision instrument dont screw the screw tight or it will bugger the carb.
jet sizing starts here
whats your engine built to spin up to ----------- no lies please
Whats the cc per cylender-------------
what do you want drivability and torque or drag strip i recomend torque.

4500 revs to 5000 is stock due to valve springs
1600 cc = 32 mm venturi for a 6000 rev motor you want 34mm venturi
right for the simple bit main fuel jet needs to be about 4 x the venturi figure if you are inbetween jet sizes go up to the nearest never down. ie 136 = 140

Air corrector jets need to be 180
if you have two sets of velocity stacks always use the long ones.
bang them on with the fuel set to 2 psi on the regulator.
Set the linkage so thay are the same length and the swing is exactly the same. only use cb performance hex bar the rest are crap
keep the air by pass screws shut .
thats it for pri tuning and i promis the bugger will run. then drive it round or call me for the final sweet tune. and ballence.

most people run to big a carb for there engine because its "cool" what horse. with a venturi to big the air speed slows down and it is this air speed that drags the fuel into the venturi. this is where the fuel is smashed into vapour by the rushing air. the finer the vapour the faster the burn and your power slow down the air and the vapour is not so fine and you get less power.
Sorry if i have talked down to any one but i keep it simple stupid and find it best. and it works.

Morning dude Smile

Ok here the info:

whats your engine built to spin up to ????
Not sure to be completely honest, as I bought it off a friend who had other plans for his bus & this engine was in the bus when he bought it & it only has a few hundred miles on it, so I got it for a decent price!
This is a description of the comparable engine that I found on the engine builders website if it helps:

Bolt up rocker shaft
crack tested crankcase
case and heads machined for 90.5 barrels
Heavy duty Scat push rods
8 dowel flywheel to crankshaft
refaced flywheel
accurate line bored crankcase and thrust face cut (see machining for details)
reground crankshaft (But might be an aftermarket mild cam, not sure)
new crank and cam bearings, new oil pump, 90.5 mm barrels, pistons and rings, push rod tubes, cylinder heads, valves springs and collars, standard camshaft and followers, gaskets and seals, con rod bushes
gaskets to fit ancillaries
pressure test oil cooler


Whats the cc per cylinder 1776cc / 4 = 444cc

My Dells are 36's & were vapour cleaned before reassemby.
I will get back to you when I find out what sizes of Venturi's, jets etc were fitted to them. And yes I got the CB hex set up for them!

Andy cheers for this fella Wink

Ok listen carefully
this is no bulshit
you have not mentioned double valve springs so i will presume the heads have only single valve springs per valve. it will only rev to about 5000-5500 max revs before the valves bounce and limit your power. so i would have 34 mm venturies but its in a bus so fit 32mm as it will give more bottom end torque. guess what you have them fitted so dont worry. you will need an electric fuel pump if you dont have one already and a fuel regulator. the stock pump is not man enough top end ie 70 mph and you will feel the car/ van surging. refur back to my last post for the jet sizes. check them out. and base set up values. your away dude. an expert just like me. an ex is something that has been and a spurt is a drip under pressure. lol

PostSubject: Ker boom   Tue Feb 19, 2008 10:50 pm

hi there are 3 or 4 ways of doing it.
vent the tank or get rid of fumes you could set fire to it not recomended

fill it with water and try to weld wet steel. you also still get a small boom because you cant fill it full

you can purge it with co2 or argo shield whilst welding. by teeing off the migs supply

start another car and pipe the exhaust into the tank whilst welding

Remember fuel vapour is heavyer than air so needs to fall out of the tank but you also need the let air in.

my tank was old and smelly but it was washed out very well with soapy water and then rinsed very well left to dry and then heated gentaly to evaporate the fumes ie in the sun or better still a green house it did it for me. Go carefull though you can blow all the fumes out with compressed air on you compressor . i go the gas filling route most times
