First Start on 1969 w115/Gas - Help Please

Short history - My 1969 w115, 220 gaser was given to me. It had sat for at least 4+ years and was put away a mess. I rebuilt the Stromberg Carb from top to bottom, replaced all gaskets for manifolds, checked spark etc., hooked up the water choke too, new gas - the works. Yes I have a new diaphram and ATF in the top.

So I get it to turn over, cough, gag, catch catch and it starts to run on it's own . . . but only with the pedal all the way to the floor - it starts to smooth out pretty well at a mid range rpm and goes no higher even though the pedal is on the floor - as soon as you come off the accelerator it dies. Where do I go from here . . . These carbs are new to me . . . Help.

Chris

Make sure it's not a vacuum leak at the brake booster hose connections or a timing issue.

Good point on the vacuum from the booster, the former owner did mention a possible problem issue with the brake booster . . . And if it was leaking that would be an issue. I should not assume th timing is correct, another good point and one I should double check for sure. Thanks, kip those ideas coming!

If you suspect brake booster trouble then just pull the vac line from it and plug it. I would not drive the car this way but it could help you figure out if that was your idle problem.

You might try adjusting the air/fuel ratio on the Stromburg. As I recall this is done with an adjusting screw on the bottom of the carb.

Do you have the correct level of oil in your upper carb chamber? If this is a Stromburg sidedraft that is a rather critical area. With no oil in the chamber the carb piston jumps up too quick and you will flood the engine.
