Sidedraft 26VA running from gravity tank. Plenty of fuel visible coming through the modern inline filter at all times.
Running was fine on accuspark distributor [but I've changed over to a self-rebuilt DK4, co-incidentally].
Car idles very low and sits running in drive for 3/4 hour fine. When I start road testing, when it has got warm I get kangarooing and it grinds to halt. Then restarts and gets going again with lots of pedal.
I've been through all jets, the hidden jet, and cleaned the emusion block (but am waiting to fit new gasket there)
Does it sound like something to do with float height (which I am yet to understand)?
I have changed over a float bowl (I've checked they are the right type for the main body as per Ruairidh's comment on thread elsewhere) and the problem got worse, so that obviously disturbed something or contributed to the problem.
Could it be fuel vapourisation when the sidedraft carb is so high above the exhaust, or can I discount that? It was warm that day but not that warm.
I can't see to duplicate the problem when operating throttle in drive (and haven't wanted to run it hard under no load)
