Help

Hi people,

1.5 carb

Been having a few probs on idle over the past week.

When cold she is fine, only when she warms up that it seems to have a misfire on idle. revs drop then back up. only about 100 or 200 revs. Just like flicking a light on and off.

I can give her some down the road with no probs

Seems to be getting worse, at idle only but an intermittant fault. sometimes sweet and sometimes not

Misfire and now sometimes the revs drop right down so the rev counter don't move but she still ticks over but then sometimes cuts out.

Sometimes would cut out and missfire but then back to norm for a few mins then same probs

I can sit there in traffic or at the lights just giving her a bit of throttle and she will have slight misfire at 1000 revs and no miss at 1500 up.

Bits changed:

Air Filter/Fuel filter/jet clean in carb.
Plugs/leads/rotor and dizzy cap.
Points changed last year

Help needed

Cheers
Tucker

Not sure if I can offer any advice, but what carb do these have?
