hey guys. have bought another chevette recently  but unfortunately will not start up for me  . have new cap/rotor/points plugs & leads look ok. set timing , points gap etc. as far as i can see everything is set the way it should be for ignition. shes a stock 77 sedan. starter seems a bit slow to turn sometimes & needs a little encouragement to turn(quick whack with my adjustable wrench  ). carb seems to be getting fuel but is just coughing rather than firing. air filter looks alright too. when i first cranked her she fired up for a few seconds then died as if there was no fuel.  so since then have checked fuel pump & seems fine. swapped coil from other 'vette & nothing. put a new cap/rotor & points in. so now im running out of ideas.  any help would be greatly appreciated ;D |

if it starts and then stops check fuel line for blockage.

hey thanks man. yeah i tried that but nada. fuels getting to the carb ok but i think its spitting it out. coz i get a psst sound when i crank it, then fuel dripping out the side of the carb like she's pissing herself or something?!? lol  im guessing that means either the timings out or somethings up with the carb. |

yeah exactly. i guess im on the right forum though eh! lol. i topped the damper up already yeah. gonna give it another crack tomorrow. see what else i can think of. might try changing carbs. :S see if that makes any difference. if not problems obviously elsewhere!?! if its getting fuel im thinking a spark problem somewhere. hmmmm...

As it's flooding out the carbie - stuck and/or dirty needle valve!
While you're at it, replace the diaphram - there should be one in the kit.

it's either your carb or your distributor is not connected up right.....eg plug 1 isn't 1 on the cap when the engine thinks it is (hope that made sense).
I had to take my carb off and completely clean it with petrol (try not to get any on the rubber diaphram as they don't like sitting in it.) Was running like a dog.

ok. yeah i know what u mean. going to strip carb tomorrow. try to anyway as the screw heads are pretty worn. looks like some hack has already had a few goes at opening it up. succesful or not i dont know. as its not working im guessing not! lol. hopefully should solve the problem . if not..... :S haha. cheers for the help anyway guys. might throw some pics up of the little beast. not a bad little car for 6 hundy! reg on hold and no wof. considering what that other 'vette went for the other day on trademe. just under 2 grand?!?!? that same guy wanted to sell me a viva gasket set for 40 bucks. lol apparently he was bidding for a mate with no computer. |

i think pre 1970 were 1159? all the gaskets look similar except the exhaust manifold which looks a different shape. maybe the intake man is slightly different as well. theres one for sale on trademe with a pic. tried to get the guy down to 50 bucks incl. postage but he wasnt keen. i know rip-offco do one for 65. but the one on trademe's got O rings i think & air & water pump gaskets as well. hmmmm?!?!? :S |

na all good tim. got about 5 already. lol stripped carb today (had to tap some new grooves in the screws because they were all totally worn. diaphragm had a very small tear at the edge?! not sure that would have much of an effect :S so then cleaned the whole unit. i think needle was a little stiff. put her back together & back on the car. then starter motor decided to have a hissy!!! checked the voltage & its only getting 7-8 volts. im thinking either dodgy cable or solenoid.

ANY tear in the diaphram will fornicate the carb operation as it kills the vacuum that lifts the piston/needle assembly.

but unfortunately will not start up for me 
. have new cap/rotor/points plugs & leads look ok. set timing , points gap etc. as far as i can see everything is set the way it should be for ignition. shes a stock 77 sedan. starter seems a bit slow to turn sometimes & needs a little encouragement to turn(quick whack with my adjustable wrench 
). carb seems to be getting fuel but is just coughing rather than firing. air filter looks alright too. when i first cranked her she fired up for a few seconds then died as if there was no fuel. 
so since then have checked fuel pump & seems fine. swapped coil from other 'vette & nothing. put a new cap/rotor & points in. so now im running out of ideas. 
im guessing that means either the timings out or somethings up with the carb.
