my dashpots was dry and sticking.

B B I don't know much about the PI, but I had the same problem a while ago
with carbs and it was fuel related.
B B Does the PI have any kind of filter or screen in line? Could it be debris
in the fuel system or a partial clog?
B B Are you running braided lines? B They can deteriorate inside. Do you run a
pressure gauge and if so, what does the presure do? What happens if you
switch off the fuel pump (I'm assuming it's electric) for a couple seconds ,
then switch it back on?
B B A wise man once told me that about half of ignition problems were actually
fuel related. Or maybe it was the other way around; I'm getting old and
sometimes forget! Either way, check all possibilities.
