I have been working on a Bf70a an to start with it had been setting for a year or 2 so attempted to rebuild carbs an couldnt ever seen to get a couple passages cleaned so I just ordered a whole new intake. By the way leak down is less than 5 percent an compression is good. The engine still wants to lean cough upon acceleration. You can close the choke an the engine will stop hesitating but not die out like it should. Have sync an linked carbs with vaccummate an still no luck but what I have noticed is on #1 cylinder I noticed when pulling sparkplug wire it wasnt running as strong on it as the others so thinking problem is around there somewhere. Pilot screws have been adjusted anywhere from 1 to 3 turns with no luck. Engine is also in time thanks any ideas or experience would be greatly appreciated thanks
