Stromberg and hills

[Seriestwo]

Hi guys and gals, I read on here somewhere and I cant seem to find it again a guide on modifying a Stromberg carby so it will work on hills. I am currently working on a landy with a holden 186 in it and it needs the carby rebuilt so I thought I would do it while its off.

Thanks in advance.

I can testify to the problem....

for your entertainment. :D

The hill was steeper than it looks.... a rodeo struggles to get as far as I did without spinning and stalling etc....

The only way I know to fix it is to put in a 200tdi! haha no I think I heard somewhere that there is a fix but I don't know what it is.

When I had a series with a Holden motor the stromberg carby worked fine even on steep hills but then I made the mistake of fitting a 350 Holley which was an absolute bitch on hills. Can't remember how may steep jump ups I rolled back down before i ditched it. Complete waste of money it was.

Many years ago I saw a dune buggy running a single Stromberg. His method of level control was to drill a hole in the cover close to the venturi side, a tube was inserted to just above the float level and an electric pump attached. In steep country you would switch on the pump and siphon off the excess fuel and return it to the tank.

Failing that fit LPG, it works the same at any angle.

The usual process in Land Rovers was to lower the float level by bending the arm.

race cars used to do much like Bee Utey suggests, I seem to remember that they removed the needle and seat then ran a return line to the fuel tank. It also required a high volume electric fuel pump and think they also filled much of the space in the float bowl that blocked everything other than the jets.

strombergs have a better "angle" of use than SU carbs..Thats why they used them on 101's

you could angle the carbs to gain an uphill advantage as downhill may be trailing throttle.

Thanks for the replies, from what I remember it was a PITA I might look into drilling a hole and running a fuel reg with a return, I spoke to a Carburetor "expert" this afternoon and he said he should be able to work out something.

But I have been keeping an eye out for a Landy 2.25 or a 200tdi to replace the holden with but they are pretty hard to find in good condition, and for the price I want to pay for it. I have 4 series 2s and 3 have bloody holden engines, the other has its original 2l petrol. Oh the joys of owning a Frankenstein.

You could always put a carby from a 2.25 on the holden and see how that goes. Afterall strombergs worked on the 2.25's so the reverse may be successful, just have to open the jets up a bit.
As for the setting a stromberg up to cope with the hills Brian Hjelm can help you with that information.

You need to get some petroleum resistant plastic and cut out a packer to fill as much of the float bowl space around the float as you can without interfering with fuel flow. You still use the needle and seat. Get an electric fuel pump, fit a tee-piece in the fuel line ahead of the carb. A pressure regulator should be in the line between the tee and the bowl. A return line to the tank or the tank side of the pump from the tee. Your carb is then operating virtually on constant flow rather than the fluttering on-off flow of a normal float and bowl.

Some early Porsche 911 had downdraft Weber carbs with bowl but no floats. They had adjustable overflow ports that returned excess fuel to the tank and regulated fuel level. PIA to adjust and get right.

These are downdraught strombergs not side draught CD's like the RRC/101's.

Another option is you can fit a webber from a XE/XF(?) falcon. Cheap and still available new, easily adapted & jetted to suit and auto choke.

Another fix is to turn the carby around 180 degrees.
I saw it once on a forum somewhere and it supposedly worked well as the problem usually is the float bowl spilling fuel into the carb throat.
Another way may be to make a wedge shaped gasket and lean the carby forward a bit.

I have been talking to Recarb on the sunshine coast. He gave me a list of about 18 different carbies that can be used on a holden red engine. He suggested the use of a carburettor off of a 2.6 Landy as they are quite easy to work on (plus I have one at home). He will make the adaptor and rejet it to suit and it should work fine.
