Hi , Everybody ,
I'm a virgin so please be gentle with me ..
I'm an old aged Pension , so the $$'s are few and far between.and can't afford to pay for repairs .

I have a Victa, Mustang Self propelled 20" with a High Performance Straight induction. and Ramflow Engine Pak. . It is about 20 yr old.

I haven't used the Mower for quite a while , after cleaning out old Petrol (that wouldn't work ) replaced the Drive belt with car fan belt. .... the Mower now starts easy and runs good.
I think it use to have Auto Throttle Control ???, so when it hit the Longer Grass it would Rev more and Rev less when no load.
Now it is only Revving when you use Accelerator , and then it Revs too hard when in short grass, and drives too fast too.

I was wondering if there was anybody coud tell me if it did have Auto Throttle,
How does it work ?? and what the usual fix is ??

It would be much appreciated .

Thanks Ron
