K-Jet Injector Delivery Testing

I am having issues with rough / non idle after a cambelt change and wanted to rule out fuelling issues.

Can anyone recommend a measuring tube capacity I should get 4 of to test the spray pattern and quantity delivered. is 250ml tubes overkill?

Thanks

I used 260ml baby bottles that I got off eBay for about £4. I found them about the right size, I wouldn't want to go much smaller.
Just out of interest, have you checked your valve and ignition timing? It seems strange that it all went wrong after you changed the belt.
