He should have seen that coming... Uncanny...

Just gave it a run and it started up ok, ran perfectly for 5 or 10 minutes so decided to take it for a drive. Drove well, but going down a hill at 2000rpm started backfiring. Normally it backfires a bit if you're going down a steepish incline at about 3000, never like this. Shortly after driving around nicely, it started running roughly and coughed a bit so I pulled over. Idled like it was yesterday, and conked out. Started it up, and the idle went back to normal after about a minute or two. Drove again, now taking more notice of the engine sounds. It seems to backfire a little bit driving at a constant speed, as well as pretty bad when youre slowing down by the engine. Note : pretty bad means every second or two it burbles or splutters. No big bangs or anything. Repeated the same thing a few times, and without fail the engine started to go rough after a minute or so of driving. Did the same with the air filter off. Both carbs sucking, the back carb possibly sucking a little less air than the right. Still sounds like fuel starvation to me, but the fuel pump is bubbling away normally. Dad wants to take the carbs off and spend hours investigating. I want to ring the mechanic.

That's it, I dont *know* for sure. Like I said in my original post the mechanic fitted a new fuel pump (or so he said), adjusted the carbs a bit (to get a lower idle for me, and sprayed WD40 or something similar on the bottom of the carbs where the little pin thing comes down when the choke is on (it was not coming back up). That was all he did to the fuel system. He was not doing a service, but I had one of those done by a different mechanic a while ago. He's the one who put the chip in by bonnet so that's why I moved to this new guy, who has a rally 240Z which he takes to Targa Tasmania etc. and also a rally 1600 I think he uses at the moment for rallying in. He does work to all sorts of other rally cars (had a Mini Cooper S, Mk 1 Lotus Escort, Datsun 1600 in his garage when I picked mine up). You'd THINK he'd be good with my car. Again, I dont *know*... The fuel pump was replaced because it was spurting oil everywhere. Could this be a tell-tale sign of something other than just a worn out pump?

Thanks guys, sounds like it needs a new fuel filter anyway, but I just can't stop thinking that it is a very large coincidence that this happened straight after the mechanic fiddled around with stuff...

I looked at it yesterday and that's the first thing I will check tomorrow, just with all the bad stuff happening yesterday I felt it was best to leave it. Thanks for your help. The filter container is full to the brim and very dark, whether this means anything or not I'm not sure... I'll take it out tomorrow and get all dirty :classic: Edit: How often should your fuel filter be changed, anyway???

Hi guys Was up a mountain yesterday when my engine decided to cough and splutter and generally just not run well at less than about 2500rpm.. I pulled over immediately to have a listen but after about 4 seconds of idling at around 500 (usually around 700) it conked out. Fiddled around for a while, but my bonnet cable broke again that same morning so it was a bit useless! Anyway, tow truck came along and got me back home for 60 bucks AUD (not bad I thought) and he also helped me get my bonnet open (gave it a good yank and pressed down on the bonnet at the same time). The car was just in the shop last week (got it back Friday) getting $500 worth of stuff fixed up. I think this problem is something to do with the fuel line - the mechanic gave me a new fuel pump and the carbs were adjusted. Do you think this is related? I drove it about 40-50 km on Friday and it ran well despite idling a little weirdly occasionally, but I thought I was just getting used to the new lower idle setting and other things which were changed. Up the mountain it was good all day until 3pm when it died. Before this the car was running very well, no smoke (I was told from the guy behind me) and I only revved it up to 4000/4500 maximum. Any ideas?

Search for "Watanabe" in the old threads. You won't be happy with the price

yes. yes it is.

Peraps peraps ! So your distant relatives came over by boat as convicts? Do you know when?

So, how is he at the moment? I've seen many of his videos and he seems like a pretty ..... crazy guy. He's the kinda guy who lives for danger, from what I saw.

I've heard of people taking OFF their louvres, but putting them on?!?!?!?! If that's your car in your avatar BadDog, burn that large staircase of metal and do not think about such an uglifier again!

"Honey, I didn't realise you liked that kind of pop music?" I bet some of your wives have told you that before!

I am proud of my penal heritage, if you know what I mean LOL LOL No, I didn't decent from no stinkin' crooks Our family came over from Scotland by choice a good 80 years ago or so...

If it's any consolation, my car broke down today 40km from home, and still does not work. the z..............

Yep, I'll scan you a shot or two when I am not depressed...

heheheheh we dont get ads like that in australia

Japan, eh? You're in Z Car heaven!!! Welcome to the club, and I just have to say I've seen a lot of bonnet buldges on Zed's and I haven't liked any of them, until now. Nice work, I just hope the Japanese don't give you too much slack for your "American bastardisation"! That 2+2 G-Nose Zed you had is loony!

The holes in the floorpan could be your drainage holes... are they like these holes: http://www.classiczcars.com/photopost/showphoto.php?photo=2991&papass=&sort=1&thecat=998 No not those huge gaping holes at the front, the round ones in the middle of the floor. Get some pics

It's everywhere it's everywhere!!! :(

errchkk... pretty gruesome. Almost as bad as the picture of a deer that thought it could jump a fence.............................:sick:

Craig, Until yesterday, the badges you wanted were for auction on ebay Australia... I have a spare new choke handle thing somewhere, if I'm thinking of the same part you are. I'll scan a picture in for you if you're interested...

:tapemouth :tapemouth :tapemouth :mad: :mad: :sleepy: :ermm: :mad: Never had to do anything like that, but I can tell you now it won't be cheap mate...

I will feel ashamed if protests muck up Anzac day. That sort of thing is just NOT ON. I do not respect those who have no respect for what our countrymen did for us. The fact that no one seems to care about Australia's involvement in this war is mainly because we are still a small fish compared to America and the UK, however great we like to think we are. Also the Australian military being tight-arsed about details regarding what we're doing over there isn't helping either. I didn't know what Australian troops were doing until you posted your message Rick. Now at least I know we're serving some purpose...
