Possibly.

When you say 'developed' do you really mean it's only just started to happen or you've only just started to notice it?
I'd start by checking the EXUP - never wasted time on a Gen 1 - and experiment with TPS setting after that.
Advance the spark slightly by rotating the TPS unit so that the tacho reading bounces between 5 - 10k rpm. Or try Ivan's engine-running method (see Pat's Site) ... it has the same effect.
