carb sync

Postby legstoshort » Thu Nov 13, 2014 3:07 pm



Hi,(its me again),
made manometer as seen on goldwingdocs using just pipe and valves for fish tanks and I must say it works brilliantly and much cheaper than buying gauges.
I put mmo in pipes as it is a lovely red colour and can be seen easily.
I am only syncing one carb at a time to number three carb (is carb three non adjustable)so I can see at once that number one carb was out my a lot (mmo in carb three went high up in pipe and mmo in pipe connected to one carb went low, but I cannot adjust carb one to get mmo oil to same level as in pipr for number three carb ?
When I put pipe on number two carb same thing,also I think I can see what looks like petrol going into pipe, I have not done carb four yet.
I know some one out there can help me. Thanks in advance.

You're doing it wrong. First sync carb 1 and 3 together and make sure they are balanced (you adjust carb 1 to match 3).

Next, sync carbs 2 and 4 together, using the balancing screw closest to the front (adjusting carb to to match 4).

Lastly, sync carbs 2&4 to 1&3 (balancing one side to the other) using the balancing screw on the left side closest to the back. This adjusts carbs 2 & 4 together to match 1 & 3.
