Carbie problem ??

[Bubba]

up date, fitted snorkle a while back works great but the template that came with it was shit , had the problem again the other day, just out of the blue, finally replaced the throtle cable which i have had sitting in the back of the troll for to long , the old one was very frayed, runs much better now should have done it as soon as I got it , will what and see if it happens again

[Bubba]

it has happened again, bugga, something must be sticking coz when I play around with the throtle cable and spray the carby with WD or the like it stops
got me scratching my head

HI mate,

I am having the exact same issue with my 3.0 Gq patrol at the moment. I have replaced, spark plugs and leads, cleaned carby, changed air filter, fuel filter and still having the same problem.
I have been told to check the fuel site glass on the carby straight away when it happens to see if the fuel is at half way otherwise it could be starving for fuel.

I will post here with my outcome, hope to fix this issue soon.
cheers!

i will do the same but it has only happened 3 times in the 8 months i have owned it so who knows when it will happen again

My rb30 had the same stuff happening when I bought it. I put it on a Dyno and was getting a whopping 30kw at the wheels. The Mechanic fiddled with the second stage butterfly. He found it was stuck shut. The engine immediately gave us 70kw. He advised me to take the carby off and have a go at the second stage with wet'n'dry. I found that the butterfly had worn a groove in the bore. I smoothed the butterfly and the bore. It took me quite a few goes to get it right, but persistence paid off. It has had no such problems, for over 12months.

Another thing I did was to refit the stove pipe and check that the flap works, as the carby would fail worse when cold.

Cheers Mate, will have a look at what you mentioned.

Update:
OK, so I have replaced the Distributor cap and Rotor button on my GQ. The original one was pretty ratshit and suprised it threw any spark at all going by the condition it was in. Since replacing both parts I have not had any issue with loss of revs/power. Its been a week and considering before it would do it every time I drove it, I think I may have solved that issue... now onto the 100's other issues.

Hey Taslucas, I am still having issues with my carbie, problem only happens once iun a blue moon ussally when we are loaded up and going on a trip or an outing , the rubber boot in above photo is completely perish on my carbie, so my thinking is I need to get a new one. question is where? do I have to go to Mr Nissan for it?

I was having problems with mine untill it just started farting and cutting out.
Turned out the LPG had deteriorated the internals. Got them all replaced new seals/gaskets and tin components intead of the plastics. Had to get a body too as id somehow warped it, its been sweet since.

I did put a snorkel on recently and it when i got it retuned we discovered the lpg system didnt have a equalising pipe i think it was, so sometimes it would cut out when comin of the gas down a hill.
Got one fitted now it runs better than ever.

Are you running on LPG at all?
