Bit of trouble

[Michael Elite]

Don,t understand what happened to my landie the other night but i just finished doing the brushes on it and the clutch master cylinder and then i did the clutch kit also so the gear box was fine which was the problem before. But i went and took it out for a drive tonight then it was running fine then all of a sudden it started mucking around and blowing massive flames out of the exhaust and backfiring but are i dont no i thought i blew the ignition coil but i didnt so im not sure.
Thanks in advance:BigThumb:

Sounds like possibly the ignition timing has slipped or it has at least one cylinder misfiring (and accumulating fuel in the exhaust, which then burns), possibly due to either a faulty plug or lead or cracked distributor cap, or a stuck or broken valve.

Yeah i got it running today. I replaced the ignition coil and got genuine points for it a new condenser and leads new dizzy and made a new earth lead from the coil to the dizzy. But after putting it all together i found out that the distributor cap is cracked just were the main lead to the ignition coil goes. So im thinking thats y it running on 3 cylinders.

Just Replaced the dizzy cap today and found that it seems to still do it. What it does is it starts running alright then it will start jerking around and backfiring and blowing flames and really playing up im really stoked really dont no what the problem is i mean everything is replaced.

Hi Michael

Have you checked the fuel filter?:(

I had a school bus come into the workshop one day that sounded like you described. I changed everything like you and spent the day thinking and scratching my head.:confused::confused:

By chance I decided to change the fuel filter and it ran like a dream.

Cheers Nev.:):)

Nah haven't checked that ill check it tomorrow.
Thanks anyway:BigThumb:

Thinking about it after reading Nev's post, anything that gives a weak mixture, not just the fuel filter, can give these effects. This includes leaking gasket on the intake manifold or under the carburetter, or a blocked passage in the carburetter, or a faulty fuel pump or the pickup screen in the tank blocked.

yeh now that you say that thats when we started having troubles the first time it did it we saw this wet substance just were the carby bolts to the manifold. So that might be the problem.
