I will keep it short & sweet:
- congrats at 18 yrs old on joining a great hobby.
- putting the car into gear & starting to accelerate is not a secondaries or air valve [ AV ] problem; this assumes the AV spring is adjusted to 1 1/4 turns or tighter.
- since the carb has been apart a few times, maybe the o rings that sit in the black body have been lost....which will cause a rich mixture....& stalling. If they have been lost, or their condition is suspect, buy some standard fuel resistant O section o rings, 7/16" or 3/8" OD & 1/16" wall thickness.
- make sure the met rod hangar moves freely, that the met rods are attached & that the dimples on the hangar face the choke wall.
- in the centre of the hangar [H] is a small screw; it is a pre-load for the met rod position. To adjust, back of the idle speed screw until it no longer touches the arm. Back out the small H screw until it sticks up slightly above the H. With throttle blades bottomed in the bores & H pushed down with your fingers touching the H AND the choke wall, screw in H screw until you just start to feel the hangar rise; at this point, screw in the H screw a further 1.5 turns. Reset idle speed screw.
- choke is fully open when warmed up.
- float level is correct: 1" for brass floats; 7/8" for nitrophyl. no gaskets needed if you are careful.
Report back after trying the above.
