Hi all. I have a A4 that ran great on the hard but is sputtering and dying out when I try to increase RPMs in FWD now that I'm in the water. Out of gear when i increase RPMs it kind of hesitates a bit on the way up but gets there. In FWD I can get the RPMs up a bit but when I apply more throttle RPMs drop, the engine sputters then quits completely. However, with the choke pulled out I can increase RPMs right up but it just doesn't sound right when I do that.
Thre A4 is a late 90s (from what I'm told) Moyer marine A4. Electronic ignition. I've just done a refit of my Tartan 30, and part of that was a new fuel tank, new lines and filter, oil changed, new plugs. I've cleaned the glass bowl out on the carb and I've blasted carb cleaner into the carb after taking off the flame arrestor, but I continue to have the problem. The hour meter (which works) shows 486 total hours. Not sure if that represents actual hours since install.
I'm thinking of trying to adjust the lean/rich mix screw as if the choke is pulled I can rev up ok, which tells me I'm to lean right now (right??) but before I did that I thought I'd join here at Moyer and ask for help on the issue.
I look forward to hearing your opinions. Thanks!
