410 rough lumpy idle

My engine is seriously struggling to idle...

Will run with a touch of choke ok, but at normal idle it's lumpy and shakes the car before cutting out. Also means I'll sometimes come to a junction and she'll quietly die!

Thought of trying turning the idle adjust up a tad to seeing it would help but can't even find the screw!

Thoughts anyone?

1st thing first try a new fuel filter.

2nd check the points gap...0.40 - 0.50mm

3rd give the carb a strip down and clean http://www.suzukiclubuk.co.uk/diy/15-en ... pand-clean

4th check the timing 10* before tdc @850rpm

New filter ordered - we'll see how it goes!

Thanks again Scottie

No better, gap check tomorrow...

It's loud mid exhaust too - there's pressure at the back so don't think there's a hole but I'll get a better look tomorrow.

Need a local SJ owner!

1 and 2 done and it's better - idles now!

Still rough though, lumpy across the Rev range.

Tried the carb... Though fuel filler plate is well and truly stuck down...
