Hand Throttle for a Sierra

[Mudzuki]

Ok, im sick of doing climbs and as soon as i have to stop (clutch and brakes) the zuk stalls. Had a search around and could only see that christover had one, but no details.

I know that they are generally just a bike gear lever, but how are they setup on a zuk?

Can you set it up so that it will lift the idle speed temporarily to 2000rpm, and still be able to use the throttle to?

Any pics of setups would be great to.

Cheers

I used to have a hand throttle on mine. I just used a bike gear lever that was attached to the side of the instrument cluster. A cable then ran through to a small bracket on the throttle lever on the carby. You can then just adjust it to whatever rpm you wanted. haven't got around to fixing it yet but it worked great before I did the engine swap

Mine was a 1.0 litre b4 I 1.3'd it, so I had the old choke cable to use for the hand throttle.
I removed all the automatic idle up bits off front of carb, and used that for connection of hand throttle.
I cut an old carb to get a piece for the cable to hook on, and bolted it to side of original auto idle up bit.
And made a support for cable on side of carb.
This can be used as a hand throttle/idle adjust and you can still use foot pedal normally. I use it on hill starts, saves using useless hand brake, and I idle it up when cold etc.

On the mokes, we used any choke cable you could get, and connected them to top of foot pedal.

MQ patrol hand throttle works well.

Fuel Miser list (or at least they used to) a hand throttle/manual choke for a Sierra 1.3. I haven't got a Fuel Miser book to get you the P/No. but essentially it was the like choke set up on a Sierra 1.0.

if you want about 2grand out of it, turn the park lights on... power idle up should be about that from memory...

whats wrong with just revving it up when u start the car? ;| :|

I know you are just being funny. But.
I fitted mine mainly cos of poor hearing.
Sometimes in noisey situations it would stall, and I didn't know till I went to take off and nothing happened. Usually in peak hour traffic.
I know I got a warning light, but I aint always looking.
Wasn't really an issue Off road, as I can feel stall before it happens.
Though when carbs aint perfect, they can be a pain at low idle.
But it has been very useful for steep hill starts. Cruddy handbrakes.
Also very useful to set a constant speed, so on very bumpy extreme tracks, your foot dont bump the pedal at wrong time.
It can be useful to set a minimum throttle in case foot slips off, like in rough bogholes or rocky ledges. I set it to an unstallable idle.
I also get foot/leg cramps on long trips, so hand throttle can be useful.
It's not acceptable in most comps, for safety, unless it returns to idle by itself, so either use a pushbike lever, or call it an idle adjuster, not a throttle

the engine is cold and wears out very easily. Making the engine life shorter. I reckon letting it idle or be under 2000 RPM is best when cold. Big no no reving it

[RB zook]

thinking of doing it to mine

always when offroad and on steep angles the car tends to want to idol below 700

with the throtel could just idol it up a little bit so it doesnt tend to want to stall

[christover1]

On later models, you could easily wire in a switch for higher idle, sort of trick it into thinking lights are on, or aircon etc...tho no choices of rpm.

better than the hatchet job I done.
worth a thought

I think the bike shifter is the go.

Its not for cold starts, its just to stop the car stalling on really step climbs. It may be useful for upping the idle in comps so that your cant stall it.

Cheers for the info

I've just fitted a winch and will be fitting a handthrottle soon. Will use an old coke cable to the pedal.
On the subject of hill starts, dosn't any one know how to heel-toe any more?

If I do that, I get a severe cramp in the foot and leg, then driving becomes impossible for some time. ouch but, yep, all zook owners probably have to know how to drive without a handbrake

Idle being higher could be useful when running air pumps and the like, too, I guess.
Be careful that the hand throttle doesn't cause drag or tanglement of the foot pedal

sierras that still have the dash hole for the manual choke is a good spot to install a choke knob type hand thrittle

i made one of those motorbike lever jobs and for hill starts and fine crawling it works great , and to idle it up you just adjust the cable tensioners at either end and it doesnt affect pedal travel when more herbs are needed , takes some getting used to though (keeped pulling it out of gear ) but i am a dumb ass

I fitted one, and after trying it straight to the carby, I found I preferred attaching it to the accelerator pedal. At the carby it tends to kink the throttle cable. I screwed the bike thumb adjuster to the steel rail under the dash on the drivers side, so it's a straight pull to the pedal.

For tricky hill starts, and stops, I use two electric line lockers. One is spliced into each front brake line. I have a missile switch as a master to power up the two switches for the line lockers, just makes them safer. In some situations these also work well as fiddle/cutting brakes to make turns tighter.

thats how i did mine as well , quick and easy to do

[christover1]

I forget to back off the idle sometimes, and get a large surprise when I try to go slowly down a steep hill

Interference between the 2 cables doesn't sound bad, but can be a little dangerous, so fit anything carefully, considering all possible throttle needs.

This is the main reason I connected it to the idle up side of carby, as they both work totally independantly.
