Guest escort_boy Posted February 24, 2005 Share Posted February 24, 2005 basically it vibrates while it idles, but wen u get past 2500rpm it is smooth. what would cause this?> Quote Link to comment Share on other sites More sharing options...

Ned Posted February 25, 2005 Author Share Posted February 25, 2005 thanks for the help but its none of those and no logan, it doesnt actually run smooth at higher RPM.... it runs better but not smooth. the problem is that it's only running on the number 1 and 2 cylinder lol the plugs, leads amd connections of number 3 and 4 are fine and the timing light senses power because it flashes the spark plugs don't spark though so i'm guessing that the dizzy cap isn't connecting properly to give enough power to make a spark... but enough to set of the timing light... is that possible? the only problem with this theory is that the dizzy worked on my last engine i've been told that if i take the resistor out at the coil that it leaves the power at 12v instead of 6 so that the spark gets put into 40,000 instead of 20,000 with the resistor at place. can anyone confirm this? i don't want to kill anything but if it's possible without killing either coil, dizzy, plugs, engine etc then it'd be cool thanks for the help so far guys!!! hopefully there is someone that can help me with this because i'm lost Quote Link to comment Share on other sites More sharing options...

Ned Posted February 25, 2005 Author Share Posted February 25, 2005 i don't have a spare dizzy but i bought a new dizzy cap and it still has the same problems we did the timing and that was fine so that's not the problem, we swapped the number 1 and 2 leads with 3 and 4 and it did the same thing. we swapped the order of number 3 with number 4 to see if we had the timing order wrong and still the same problem. the next thing is to check that the points are actually openning and set the point gap to .5mm (hacksaw blade) and to swap the plugs. the plugs shouldn't be wrong but it's always good to know for sure if anyone has any advise or things we can try... Please tell me! i need to take this car to work again on monday and i dont want to take the little 50cc thing to point chev Quote Link to comment Share on other sites More sharing options...
Jerm Posted February 25, 2005 Share Posted February 25, 2005 sure you installed the dizzy right? leads in teh right order? leads aren't shit? Quote Link to comment Share on other sites More sharing options...
Ned Posted February 26, 2005 Author Share Posted February 26, 2005 the dizzy is fine, we checked that 100 times. the leads are in the right order and they aren't shit. thanks anyway jerm i set the point gap to .5mm and it opens and closes fine at the right times so thats not the problem. we pulled the plugs out, put them in the leads and tested them and they all worked fine. just a summary, All plugs fire, we've got fuel, we've got air and we've got compression. why isnt number 3 and 4 going!! the timing is good aswell so as far as i know we have all our bases coverred.... again, any help is appreciated Quote Link to comment Share on other sites More sharing options...

Ned Posted February 26, 2005 Author Share Posted February 26, 2005 the compression on all cylinders was between 180 and 185 so that great. we checked the valves and they are all moving so that seems fine. this engine is a mystery, nobody that had a look at it seems to know what the problem is Quote Link to comment Share on other sites More sharing options...
Toucan Posted February 26, 2005 Share Posted February 26, 2005 If its running rough it could just be the carb. Fiddle with the mixture screw on the carb and see if it comes right. Quote Link to comment Share on other sites More sharing options...
Guest 78lancer Posted February 27, 2005 Share Posted February 27, 2005 go to supacheap and by a new inlet/exhaust manifold gaskit, i think there about $8, my mates starlet was running shit after we put a 4k into it so we just replaced the gaskits because they had been roughed up a bit when we put the extractors on and that solved our prob Quote Link to comment Share on other sites More sharing options...

Ned Posted February 28, 2005 Author Share Posted February 28, 2005 cheers guys! i'll give that a go tonight i've already got the new gaskit so lets hope that works Quote Link to comment Share on other sites More sharing options...
4AG_Addict Posted February 28, 2005 Share Posted February 28, 2005 Even just check that the manifolds are on tight, on my brother's 3K the securing bolts on the inlet manifold were only just finger tight, causing it to run on 3 cylinders Quote Link to comment Share on other sites More sharing options...
trunk-rattlin Posted March 1, 2005 Share Posted March 1, 2005 make sure extractors dont pull into the head. put fat washers on otherwise you will blow heaps of exh. gaskets Quote Link to comment Share on other sites More sharing options...
Ned Posted March 2, 2005 Author Share Posted March 2, 2005 thanks for your help guys!!! we got it running last night we changed the gasket, points and capacitor, changed the leads to slightly better ones, made all the connections tight as f*ck and set the plug gaps a litle bit better and it ran on all 4 so now i can drive the beast the only problem is that if it's under 2000 RPM it runs a little funny but over that it purrs along great thanks again for all your help people Quote Link to comment Share on other sites More sharing options...
