misfire problem

HI



Got this problem on a 77 RA28GT.


2x twin sidedraught solex.

I have had a intermitant misfire for a while, replaced dizzy top, arm, plugs and things apart from ht leads.



Last few days the car has been fine, i kept it at low revs and drove fine, i thought if i burried the throttle the misfire would come back, so i did and yes the misfire was back, when it does that at tickover it cuts out and takes a age to start by cranking, not the usualy one quick turn and it fires up. Usually the next day the car is fine unless i bury the throttle.



I have a Haynes manual which shows the carbs, i presume its that. Would anyone tell me where to look first, if feels like a bit of dirt, had something simular feel years ago on another differerant car and i found a spec of dirt that caused the problem.



thanks

Replace the coil.

Very likely a correct answer. But since he hasn't replaced the ht wires, here's a tip.

Wait until it's dark. Find somewhere far from lights to park. Start the engine. Raise the hood. Look for arcs of light.

I was sent 2 lots of wrong ht leads, the correct ones are way out of my budget for the moment.

I had thought a air leak or dirt in the carbs, as if i have the misfire when i drive if i then burry the throttle again when it gets near the max it clears up, most of the time, i need to replace the slipping clutch this week so until then i cant fully drive and use gear ratios. etc
