mk2 golf 16v (87) Ive almost finished my rebuild of my 16v, in the process I put weber 40's on it. now im trying to start it up, engines turning over, im getting a spark, fuel pump is priming and the carbs are wet inside with petrol. but its not starting? Carbs were second-hand but was told they had come off the same car. Are there any tricks to get the thing running for the first time? Thanks in advance, Phil
almost same with mine... I had my car running two months ago, now it won't fire up. it starts two spit crap (fuel lol) out the carbs mostly the 1st one and no others, there is fuel lying in the carbs too, just where the trumpet meets the carb.. Any idea why it's spitting case if it sparks which i'm sure it has done before it'll ruin my nice new itg filters cheers plus i have just replaced my kr with another and it was all set up 12 months (500 miles) ago costing the previous owner an arm and a leg!!
nope not tested that, got a facet pump and king filter mounted in the bay, do i need one of these? http://www.fastroadcars.co.uk/shop/index.php?act=viewProd&productId=211 and how would i go about adjusting the pressure if it was wrong? float level, not checked that, ill have a look into that now cheers, im total new to this so much appreciated
Thats the one! You adjust the pressure by taking the little nut off the top of the filter king, and turning the screw underneath, I forget which way is which. Should be around 2.5-3psi I think. When you say they came from the same car do you mean they are a matched pair, or they are a matched pair that also came from a KR engine?
cheers for that, yeah the whole lot, fuel, reg, carbs, lines came together from a 16v Ive checked the serials too, there a pair
Well if the engine was running when they were removed, then they should be at least in the ball park with setup and condition, so it might well be down to installation. If you shine a light down the throat and pump the throttle can you see the pump jet squirting? Vacuum leaks are a sure fire killer, are they installed with misab plates? Manifold sealed to head properly? Servo vacuum hose sealed? Vacuum advance connected to the dizzy properly? Leads on correct order? Dizzy properly adjusted?
Cam timing out, ignition too advanced? poor burn meaning mixture; still reacting when inlet opens and lighting contents of carb? When you say spitting do you mean its chucking out mixture, or making that hissy wheezing noise?
it's weezing and kinds banging out black smoke (sometimes flames) if you get what i mean, next time if i'm up and cant get it firing i'll take a vid... it's also running MS and i marked the leads out so they are all correct, its a bit tight to look down them as its in a mk1 and yes, its all on right with proper gaskets etc and the servo hose is on. cheers stewart
Not meant to be any petrol by the top of the jets, I can't really see the fuel very well in the second picture, is it just steadily leaking out when the pump is on, or only when you try to start?
plus sorry to high jack your thread phil but i thought there wasn't much point starting my own as yours seem too close too my dilemma. cheers
Sounds timing related to me, possibly sparking before inlet valve closes, I'd check the cam and ignition timing.
Cheers, will get it sorted, i thought it might be the timing as my mate done it (pretend mechanic) and did it to tdc and not timing marks as we both couldn't find any apart from the camshft one.
Cool, TDC on the flywheel (not to be confused with ignition timing mark). Notch on the cam sprocket lines up with the little triangle on the cam cover. Circles on inner cam sprockets point at each other, and line up with the surface of the head for intercam timing. Good luck!
