Hey Bigted, thanks for the reply. I did a bit of research on the operation of the carby to understand what happens in there. As I understand it, with the choke basically closed, and the throttle fly open, the air flow will draw a rich fuel mix into inlet manifold. Since I took off the air filter and cleaned that air pilot it has made a big difference, so I think that was my starting issue, which has been solved. When the mower is in the cold start position and is running, should it still be burning a bit of smoke or is the fuel mix not quite right? When I move it to the run position it really is motoring, so maybe that is good enough to leave as is? As to bending the actuation arm for the choke I think I will leave that for the moment, as I think I don't need to worry about it. If anything the fact that it is slightly open should help more air into the ventura. later today I will take off the filter and check that too. I will also check my speed reduction as I go thru the gears, but it seem to me, the throttle fly isn't being turned to reduce air so will also check that too. I take it this fly should open/close for speed control, and I wonder if the spring setting on the governor can be changed to effect this, so will check that too.
