MG TD TF 1500 - Getting Engine to Idle at 3,000 RPM

For a long time I've fiddled with trying to set/check my car's advance at 3,000 rpm. Tweaking the adjustments on the carburetors can get an idle speed of perhaps 2,000 rpm. I can readily measure the engine speed, but I can not illuminate the timing mark and TDC mark while standing on the carburetor side of the engine. Nor can I tweak the advance from that side of the car. Does anybody have a simple jury-rig method of holding the engine speed around 3,000 rpm while you're standing on the ignition side of the engine? I've even tried clothespins. TNX, Bud

TF has fast idle adjustment on the front carb, not sure if TD has that. Does not have to be turned down too far, after I am done I set it so it is just clear at idle with choke in.

Easy method.

Hi Bud. You can either just turn up the idle adjustment screw or fold a piece of paper multiple times and put it under the idle adjustment screw.

Thanks for the suggestions,folks, but the adjustment screw approach can not open the throttle far enough to go beyond about 2,000 rpm.
A fellow TD'er, Matt McDermott, sent me some images of a device that can lift the throttle linkage to its maximum. I'll be giving a try shortly.

At the moment I'm seven days beyond having had my right knee replaced. That makes both of them now. Bud

Perhaps a spreader bar type of woodworking clamp? Or just a piece of lumber cut to length between the seat and the accelerator pedal?
