All sorted. Pending a road test.
Float fixed as previously mentioned.
This car has been sitting so its all an unknown to me.
Tuning what did to get a good idle and return to idle.
Idle screws in and also air by pass screws.
By ear I adjust the air by pass screws out for a smooth idle while letting the idle screws out to lower the idle. Did this till the air by pass no longer increased idle while letting the idle screw out. Then the idle screw in so its just opening the butterfly. Then air by pass in till it runs rough and back off a tad.
Then checked the readings. All at 5 with a nice idle. 😛
Bring the revs up to 10 ( just above idle ) on the gauge and balance the carbs via the linkage to to be even.
I got high readings at idle because the butterfly where to open. With these closed to 5 and the air by pass open up it runs like a treat.
Mixtures out till no backfiring
A road test will reveal all. Next week hopefully I will have rego to drive it.
