When rebuilding my Saito engines carb, after removing everything and then re-assembling, I placed the slot in the spraybar (new part) facing straight up into the heads intake stream, as the square shape of the spray bar lined up through the barrel of the carb to allow tightening, this seemed to be correct, But I would like your opinion.
Another question, Is there an easy way to be certain that the timing marks on crank and camshaft can be lined up (and held that way) as the case is united. Engine is a fine runner and I would like to assure it stays that way, Thank you for your time R Larson
