After rebuilding carb's (1979CX 5000 std) per Larry's book I am now ready to sync carbs. I have been riding for a few weeks-only 200 miles and seems run ok. I decided to purchase this tool.

After normal op temp, the gauges are at 100 ( the inside list of numbers-I think this is MM of vaccuum); about 4 on the outside- I think this is inch of vacuum.



At least both are close together. Before, I begin on the mixture screws----any adjustments needed on the sync?



Thanks for this forum.

Ok , thanks



I just need to correct the figures--at op temp, the numbers were about 50mm/ 2.5 in. The 100 was for 4K rpm- just wanted to see how they reacted.



I know they must be within 40Hg-just was not sure about the measurements for these gauges. But as you state - I should be ok. I will must sure the screw is tight and re check the test again.

I have gotten the lock nut snug on the sync'ing screw and rather than fiddle around with tightening it, I cover the screw, nut, and plate the nut rests against in a heavy enamel paint to lock it all down. Seems to work well for me.
