Found a second adj for fuel....needle in carb barrel . Made a flywheel from 16mm plate and mounted on sprocket . What I thought was capacitors in the generators was in fact voltage trip overloads .Remember these are widow winder motors ..... Machine more controllable now on the flat but trying to climb a hill petrol motor bogs down and tank stops. On 18v drill battery goes up fine . Conclusion.... the 15 tooth sprocket on the motor is to big for the weedeater motor ...., over geared the generators so need to go down to 7 - -8 tooth ...2 to 1 reduction should give me the power I need ? We'll see !

Geared down to 10 tooth on the motor but still lack of power . On an 18V drill battery It can pull 50 AMPs as against 7 on the generators . In the process of this test I stripped one of the plastic gears . The traction Engine I built yrs ago has the same pitch gears ...16 DP and I made a Hobb for them so this is not a problem . But the lack of generator power and lack of space is .......Pics of cutting the teeth on the Lathe/verticle l slide
