Got Jeep! CJ3B Hurricane.

Jaggu · 27th April 2010, 10:46

Woke up in the morning and tossed around in the bed for a while. Got up and went downstairs and took my cuppaa. Am restless, why?

Decide to take the keys of 3B, walk to the garage area with my pet lab. While lab is busy sniffing around, i slot DwArF to neutral, plonk in the key and half a crank later without any pedal or electric pump, hurricane wakes up with a burble and idle's.

First time since i bought her, i had such an easy morning start. Usually first start means lil more cranking and lots of pedal.

It was decided, even if i have to risk the rain, i will be driving her to work. She ran perfect, though i still want to fix that packing and do a proper timing check and point setting.

What do guru's have to say about the vacuum advance of the distributor? Will it be a major issue if i don't hook it up and run on static timing? maybe advance her a point or two from stock 5 deg??

Am not as lucky as you Deepak, mech hasn't got any leads till now. :(

But i didn't ask this question coz of faulty distributor (it's working well for now), but my new carb doesn't have the tapping done for the vacuum to distributor. Also since, if am not mistaken older hurricane engine's never came with this?? So will it be a major issue if i don't run vacuum advance?

It was probably the carb clean and Fuel filter / tank cleaning + new fuel Pump that did this magic for you. Hope she runs like that from now on.

Thanks Prithvi, it was pleasure meeting you on saturday. This time its the carb cleaning and setting up the carb "properly" that helped.

The tank is brand new, but the old electric pump was still connected and the debri from the old tank was lodged inside it, i confirmed this when it was removed by the mech last weekend. So was the old fuel filter. My assumption is the debri moved onto the new carb also. Another mistake i made was not cleaning the new carb while fitting, i had moved away for lunch and by the time i got back the carb was installed and engine idling away. Though it was new, carb was stored for atleast couple of years. This was a slip from my side and hopefully its set right since yesterday.

Finally the accelerator pump and butterfly links which were not set properly, was also set right by me.

Anyways, i had to go home in between and hurricane is behaving normal. Have already spoken to a friend who can help me with the tuning equipment and maybe a solution for the vacuum tapping. Plan to execute this in 2 weeks since this weekend i have something planned

P.S. Did you meet Suresh after this?

Jaggu · 27th April 2010, 16:21

Nope he got out of the country once the deal was struck (you can use your imagination to give this a better color), he is back now but yet to bump in. But its a small world and i do have to meet up with him soon, he has to drive DwArF and then suggest further fine tuning/more trouble

DHABHAR.BEHRAM · 27th April 2010, 18:03

Dear Jaggu - if vacuum advance is not connected, nothing will happen. For God's sake Don't fiddle around with the carburettor. It would have been lying around for 20 years, not 2 years. They stopped making it long time ago.

Do I have any work in Bangalore? Let me see now -----. Abhi kuch karna hi padega.

Best regards,

Behram Dhabhar

Jaggu · 27th April 2010, 18:49

Can't help but grin

aap jaldi kutch keejiya! please do something fast and maybe transfer a team of CJ experts to one of the BLR dealership!

No Behram, i won't do anything drastic with "this" carb, a friend had spent good deal of his energy getting this for me.

When i looked at it yesterday i knew its in pristine condition, inside-out. Then i saw the brass filling, which will be a tricky affair to remove. a) i don't want it or pieces to fall inside and create problems in the delicate air passage. b) any accidental damage to the carb body.

So what i had in plan: I have the old carb with me and was thinking in terms of tapping it from the connector piece (piece that sits between carb and manifold) and use it for the experiment Or as my friend suggested try for an esteem or any other new carb with same manifold dimension and that matches Solex, these have vacuum points and this can sit between the carb and the connecting piece.

Now since you mentioned that this needn't be taken as priority, i shall keep quite! I will stick to putting a new packing and few split pins.

One more ACADEMIC doubt, heard the float level can be setup lil high to compensate for fuel starvation, in extreme incline situation? Is it a good idea?

On the other hand i heard that these carbs can be notorious for flooding up? So wont increasing the float level aggravate this possibility?

I haven't checked the level and have not changed any of the original settings that came with the carb.

Wow 20 years! If so the packing being intact saved me from great pains!

And Thank you once again, you know who you are, for getting me the carb!!!

Jaggu, if its starved of fuel, use the military spec 140 jets. That should feed enough petrol. Please check the jets they may also be 115. I was told that later on these Solex carbs came with a 115 jet for purposes of economy. Not sure how true that is but i have seen a sputtering CJ hurricane with 115 jets. Mine thankfully has the 140 jets. Even the old new carb i got, i was lucky to get a 140 jet in it.

No Gog's its more to do with muck that went inside. You are correct the new carb has 140, which i felt was running rich with the current timing set up, so i am using 130 (yes it has 130 written on it) which came with the old carb.

Common problem on "modified" carbs. Fuel leaks from the bottom of the fuel spray post, emptying the float chamber.

Pls. don't go about "modifying " the carb, esp. poking holes in it!

Lack of vac. adv. no big deal. Not there originally. Later on I think it used to be taken from the adapter, not the carb body as in other cases. Just connect a vac gauge to the adapter and see how it behaves (there should be no reading at idle/ fast idle). IIRC, that opening is connected to an internal passage in the carb.

Still waiting for everyone to post their Solex setups. I am really intriuged by the 140/ 25 combination. What air correction and emulsion tube. An emulsion tube picture would be nice as one cannot make out anything from the numbers.

Also for people "tuning" their carbs, I would strongly suggest calibrating the jets on a flow tester. On locally made jets, the numbers and the flow characteristics have practically no correlation.

Regarding flooding/ starvation, learn to live with it as just another CJ quirk.

OT
The other quirk of course is overheating. I have similar thoughts on it. Esp. because "heavy duty" radiators don't really measure up when put to an instrumented test.

After last weekend trip, i decided its better i set things right fast. If such surprise trips happen, i want the basics to be working fine before i tag DwArF along. Its not that anybody in the BLR 4x4 gang would complain, but the very idea of getting kicked left right center by these mad people scares me

So in went DwArF for:

• Full wiring
o Fuse box to be moved to top
o Wiper motor check, replace blade
o Bonnet lamp
o Ciggie lighter wiring with high amp wire and fuse. This is for spot lights/air compressor etc etc etc
o Fog lights wiring in front extra
o Remove or put more silent beeper

• Switch wiring This is not as per woriginal but my combo.
o 2 – Headlights
o 1 – Parking
o 0 – Off
o S1 – Hazard (4 indicators flash)
o S2 – Hazard + Black out Cross lights
o S3 – Hazard + Black out Cross lights + Black out head light

• Gearbox / transfer case overhaul and resetting.
o Check for any oil leaks

• Check clutch plate, pressure plate, release bearing and set with little more play

• Replace all meters

• Replace carb manifold top piece packing

• New coil with resistor, wires and plugs

• Accelerator pedal link pin

Now if somebody (esp BLR boys) has an old CJ3B rim with or without NDMS to sell please let me know. This is for the spare wheel, i plan to run these NDMS down before moving to other options.
