Once again, cheers for the help and advice, I'd never have got anywhere without it. Good luck with your own car! J.

Fastboy & Virus... outstanding Be easier to reply to you both in one go methinks.. Last time we met, so to speak, the car would 'generally' idle ok when it was just started. Once I'd run it about a bit (smokes on half+ throttle, spit test good - no proper temp sensor available) it would stall quite easily. In hindsight, I probably didn't let the car run long enough to adjust between carb settings, so I couldn't be sure if the setting was lean/rich. The 3 adjusters available to me are: flow adjuster between fuel tank and carb (hsn?), idle screw and fuel/air screw. Not sure where the lsn fits there To cut a long story short, I had a look at the old fuel that was stored with the car. I thought tho it burned ok, that it might have lost too much nitro to be any good. However, I filled the tank up and went about starting the engine. With a small increase in idle speed, the car seems a lot happier to sit idling. So I think that's the problem - the old fuel (model technics dyna glo 5) runs fine, while the one I was recommended (model tech quikfire 10) provides poor idling due to the relatively small amount of fuel required for it to idle without driving off down the road! Perhaps the 5 vs 10 fuel should have been an obvious pointer to something I was doing wrong, but I figured an increase in power could only help, so long as it didn't overheat the engine. Live and learn eh? So.. there we have it - plug everything in, use old fuel (15 years old, sealed and kept cool and in the dark) and it starts in 30 seconds and runs great! I owe you all beers/sodas On a side note, I'm assuming the old JR AM tx/rx set isn't going to cause undue problems - everything 'new' is FM.. right/wrong? PS that reads like a bunch of pages from random books, I do apologise :/ but it's at least in order J.

I tried screwing in the idle screw a bit. The revs starting to go up and it holds a little better, but still stalls easily enough. Am I meant to set the brakes to be slightly on when the throttle sticks neutral, or are the cars generally meant to roll forward a little if 'unattended' ? The clutch - took apart, cleaned and a new rubber o-ring installed of same size (that's all that stops the clutch 'plates' from engaging) Have stripped, cleaned and reasembled the rear section including the brake section which now works a bit better. Not put it back together yet. Figured I'd clean it up a bit better now that the car seems 'usable'. The carb slide seems to stick a little, almost like it's worn and now it's been cleaned up, there are areas in use that weren't used before (esp at full throttle - it would stick without the servo pushing it back). I was careful to put the screws and servo mechanism back the way they were to avoid additional confusion when initially trying to restart/adjust the engine settings, so I'll have to revisit this. Good thoughts, thanks J.

hey, good news.. had the car running yesterday and today. settings seemed so far out, I'm not surprised I was having problems. it's not perfect yet, but starts quickly from cold and flies along nicely - getting it stalling sometimes when I stop (fuel seems ok, no air etc). thx for the advice etc

Cheers Have batteries on charge and will try give that all a go tomorrow if I can. I'd be rightly stuck without you folks! Carb slide is about 5mm out currently btw - so that's some indication J.

Hi, I'm hoping to resurrect the some r/c items here and have a query.. I've acquired an old PB Nova & as such everything works. I'm having problems with the engine however. It will start (sometimes straight away) and stall, or start and try rev flat out then stall or my personal fav - start and die when I touch the throttle. I've attempted to adjust the fuel settings in an attempt to get sustained running but to no avail. (made notes and returned to original positions) I've no manuals at all & from what was said it seems likely all the fuel settings have been played with - so I'm hoping some of you kind folks have a record of what the factory/recommended settings should be and can help me? To preempt (some of) the expected questions: glow plug is fine (orange/orange white), fuel is good, fuel lines not blocked (checked & cleaned), air intake filter is ok. I disconnected the rear brake so there's little drag on the engine, just in case. On occasion there is fuel sprayed up against air filter, not sure if that's usual & could be down to the over priming. Exhaust is reasonably free of unused fuel. If there's an online version of the manual I can't find it btw :/ Thanks in advance to any suggestions J.
