rocking........

Have you checked its top speed now?

Have you checked its top speed now?

yes reached 140 very fast

gear ratios till now are as (on petrol)
1st 40-45
2nd easily 80-90
3 crosses above 120

these ratios are very fast i mean reached the mentioned gear ratio speed very quick.......

@fas and Smijaz, Guys i've already checked the whole airfilter assembly its perfectly fine and for your info, The Air Filter BOX/Assembly is brand new and it's been working gr8 for the last six months, the whole problem occured after the adjustment/setting of mixture needle. come on guys i want your expert opinion!

[smijaz]

I am in Lahore, can you please tell me of a good CNG service station where I can go?

I went last time to Butt CNG near mayani sahab qabristan.

He just adjusted the CNG air mixture nut and said it will be fine now but nothing changed.

Butt CNG you mentioned is a reliable workshop. next time ask for an expert first tell him the problem in detail and ask them to service the regulator and check the pressure valve operation properly.

xulfiqar n ijax bhai,ive this weird issue with car on petrol..
car gives black smoke on petrol,so i adjusted it thru the screw tht controls petrol flow i guess (NOT THE RPM SCREW),black smoke was less but the rpm of car increased on petrol,so i again opened it up a bit,rpm came normal but black smoke is back..
no issues on cng wat so ever...but wen cng is not available,i run car on petrol n face this problem,ive used carb cleaner but its of no use till now..
any ideas?black smoke is clearly visible..n also,wen i press acclerator,car rpm goes down dramatically,n thn rises up again wildly...so on petrol,ive to keep very lite foot n release clutch accordingly...i also poured some hi -octane in normal petrol,lyk half tank was of normal petrol, some 6 liters of hi octane i throw in...car rpm became smooth,but smoke is there....

Fuel mixture is tooo rich.

You have done it right the first time coz rise in rpm is normal when you adjust the mixture properly. Instead of returning the setting you should have adjusted rpm from the main screw ( the long one near the throttle lever) then convert to cng and adjust the CNG rpm from the CNG kit.

plus ia have another issue,not a big one but still have it..
the distributor wires r mess,the broke once n mechanic has just tapped them badly..thts not al,wire broke from very close to distributor,so is this possible to re do the wire of distributor?i mean the wires outside of distributor,tht give distributor the power!

this issue is serious no doubt, the wires can get in contact with ground or with each other causing engine to stall at any time. I had the same problem so I opened up the dissy to get rid of the broken/tapped ends by soldering them to the igniter directly. This experiment of mine costed me 2300 for the igniter coz i didnt marked the wire before removing them from the igniter and forgot which one goes where when it came to connecting them, in the end i ended up with a penalty.

to fix and remove the joint in the wire you have to sold them directly to the igniter in the dissy but be very careful about the connections.

if its not choking when you place you hand on the intake then engine is taking air from some where it should not.

check all the vacuum ports and pipe connected to the carb and idle up solenoids/diaphragms. also check the vacuum filter on the intake manifold for any open ports.

if not satisfied then post pics of air container lid inside, carburetor without filter container, filter container from underneath.

ijaz bhai rpm screw is already to its limit towards lowest rpm,the screw dont works beyond the point its been set rite now..
wen i adjust fuel mixture screw so tht black smoke dont comes out,the rpm goes high n tht rpm dont comes down no matter wat i do to rpm screw...
so i had to fiddle again with fixture screw n black smoke is back again...

[cracked]

2ndly,i think its best i shud get wires of distributor to be done by some professional,wen ever i do anything with car,results never came out favorable,so its a NO-GO for this DIY on my own:p

[cracked]

n ijaz bhai there is this another problem with car too,wen i convert car on petrol wen its warm,it goes fine..but if i keep car standing for like 4-5 hours on petrol,car wont start on petrol,no matter how many selfs..so i had to switch on cng,n wen car strts ,i put cng conveter button to middle so cng n petrol both r cut,n car runs on petrol already in pipes..
y is this so?
i mean car,wen cold,dont strts on petrol!

I went for the computerized CNG tuning of my car. He adjusted the CNG T valve and also the gas and air mixture from CNG kit. Another important thing he did is to block the air intake pipe a bit.

Now car is running is perfectly awesome. He told me if you still notice miss fires then change the coil wire.

try adjusting it thru dashpot side

[cracked]

how to adjust it thru dashpot?

[smijaz]

how to adjust it thru dashpot?

Dashpot's pin, which operates through vacuum, holds up a lever with a adjustment bolt. this lever is connected to the throttle.loosen up the adjustment bolt to reduce the idle rpm.

Yes you got the procedure right.

Lets get through this stage and then we will figure that one out, OK?
