>>>>Did you do anything to the carbs when you had them off? If not, nothing should have changed.

Nope, I only put them in a box

>>>What you need to do to synch, I think, is to set the mixture and idle speed screws to the same setting on both carbs. Then attach the linkage. Do not use the linkage to synch them, you wil chase your tail forever.

Oops I did forget to dettach the linkage

>>>If you have NO flow through one, you have a huge vac leak or the throttle plate is completely closed.

It looks like the throttle plate is open.. hard to see it though the choke even with a light ... When you say there might be a vacuum leak .. where are some likely places to check.. could it be bad tubing?

>>>Drips from atomizer (?) are bad -- if you are talking about the main fuel delivery bore, only atomized fuel, no drips. If the accelerator pump outlet is dripping, the check valve is bad and fuel is siphoning through.

Hmm it was dripping a little and then later when I looked it wasn't but I could see mist(atomized fuel) coming from it. Could it have ben dripping because the blance and idle are too high on that carb?

>>1) get engine mechanicals correct -- all valves to correct lash, manifolds sealed, etc.

All that should be good... the engine sounds great but not when it's at the correct idle speed

>>2) get ignition correct -- all plugs must fire properly and timing needs to be close.

Timing is dead on.. I guess I could still check the spark at each plug although I have no reason to suspect that they aren't all firing.

>>>3) set throttle plate stop and mixture screws to the identical number of turns from closed, linkage between carbs off. This is very important -- both carbs must have the same amount of travel.

OK I need to do this...

>>>4). Synchronize air flow with the identical mixture adjustment using the throttle stops on the carbs. When this is done, adjust mixture, if necessary, by moving the screws the same amount on both carbs, then re-check and adjust air flow to match.

>>>5). Adjust carb linkage to fix and re-attach. Recheck air flow and adjust linkage, if necessary, so that the air flow does not change when the linkage is attached.



Any suggestions for the point gaps? I'm supposed to set the gap with the breaker at the crest of the distibutor cam right?

TIA
