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

this build needs to be moved to a more appropriate section.

Have had to change the motors/generators , they would not deliver enough power . Have fitted a 24v /5amp Mig Welder Wire feed motor and machine is now able to " Wheelspin " climbing a step dirt bank as in one of the photos . I don't need full revs to achieve this either so very pleased with It. Now need to change the steering switch gear to DC variable voltage controllers , servo driven with a third servo for switching forward/ reverse . Then get on to finishing details . I have in mind a LPG gas firing gun like the bird scarers farmers use but think the small bore involved may defeat the explosion . Still thinking about this .

I follow your posts with interest and wishes for your success. I study the photos, trying to determine the orientation and purpose of all the parts. For example, I think I have found the carburetor, and I most certainly can see the newer, larger generator (motor). As you might understand, Hobbyman, all of this is rather amazing to me.

Back on It again ......Made a speed controller, resistant type to see how It would work . As I have power to burn.! So to speak! Works Ok but my motor is still not idling any good .Not happy with the carburetor and suspect the ign timing may be wrong as I want lower speed control rather than weed eater high revs . Turrent is on rollers and have made a couple of hatches .

Very clever! Good to see you making more progress.
