[Cartmaster]

Unless you have a different carb fitted to your 295 twin robin, there are no adjustments available to tune the carb. If it it flooding, it is more likely to be the float valve leaking / not sealing when the carb is full. Glad to hear you have it running though.

What makes you think the carb is flooding?

As you have only just acquired this cart, I would suggest making some checks on the condition of the engine before going much further.

First thing to check on these engines is compression. You need to do two checks. One dry and another with a T spoon of oil down the spark plug holes. These tests need to be done with the carb held open at full throttle, and the coil disconnected. The resulting figures from these tests will tell us a lot about your engine. Once we have the results, we can then go on to check other things.

If you do not have access to a compression tester right now, I would suggest removing the black valve cover on the top of the engine and checking the valve lash. You are looking for two things here. First, is a gap of .004 and second, how much thread is showing above the lock nuts on the inner two adjusters compared to the outer two. A couple of pictures of the four adjusters will also tell us a lot. But a compression test will tell us a whole lot more.

you really need to check all these things asap,

Carb float valve, compression and valve lash.

You should be able to download the engine manual in the tech section for all the relevant information.
