Chris, you're likely running short of fuel. I'd replace the fuel filter(s) and make sure to drain the carb. If there is a little water in the carb, you can run into issues when the engine needs fuel.

Bad fuel can also cause the motor to feel like it's starved. For example, this season I had a spate of bad fuel and the motor would run fine choked, but then sputter once in a while. I pumped a quart of fuel out that looked varnished and old, no problems since.

I would pump a little fuel out of the pump into a clear container. Have a look and see if it looks good. If it's dark or you get a bit of water, get the intake to the lowest point while heeling, and pump until you see good fuel.

If your tank has a top feed, with a pipe running to the bottom, you likely have a screen at the end of that. If convenient or nothing else works, I'd check that out.

A4s are pretty easy going and the only problems I've ever seen are basic mechanical or fuel related.

Definitely worth a check. My Racor filter is only one season old and I probably put less than 12 hours on the engine. For spring start-up I checked the sediment bowl on the fuel pump (mechanical) -- nothing suspect there. On a cold start, she'll catch right away on full choke and smooths out to a purr after pushing the choke in.
