My 3k Just Turned To Crap!!

[davistua06]

Alright i was on my way home from work, and then i took off this one time and the car just ran like a dog, i had to pull the choke out and managed to limp home. I had a fiddle with the mixture screw starting in little increments then just went to the extreme but still no change at all, i took had a look insede the carb and seems to be jetting alright, it doesn't blow any black smoke. Now this leads me to believe it may be some sort of ignition problem. I recently did a major service just after i bought it (about 3 weeks ago) which means it has new leads and plugs, the dizzy looks reasonably new, so i was wondering if it may be the timing is out. and help of suggestions is greatly appreciated cheers!!

carby idle mixture - screw it in till it starts to run rough then back off 1/2 a turn.

timing - anywere from 8 to 15 degrees advance

 

have you checked you dwell? i think its 52* for nippon denso and 46 for the Bosch dissy

 

 

you running a fuel filter?

yeah i did just then with the 1/2 turn but to no avail, and i don't think it has a fuel filter its nowhere in the engine bay if it doe, and forgive give I'm not familiar with dwell?

If it was running fine then everything you did to tune it was OK.

 

Sounds like a bit of dirt has got stuck in a jet, hence the choke. If not, maybe fuel pump??

 

Join Twinky in a carb strip and clean! :lol:

sounds like i may need too, although i was thinking fuel pump too. i mean it revs up fine with no load, but the as soon as you load it up it just turns to shit basically.

Did you replace the points when you did the leads and plugs? If so maybe they're slipped and closed up a bit. They don't normally just go "out of timing".

Have you got your ballast resistor (white rectangle thing near the coil) When i brought my rolla that was gone and once it got to operating temp it'd start doing that
