1981 V-225 running rough

[tc3]

The old girl was Ok again this year for about 5 minutes then ran rough and quit. Barely starts, won't idle. Purged gas line, put in stabilizer and dry gas. Output from fuel pump seem OK when discharge line disconnected. HELP?

So this is giving you trouble right after taking it from storage/winter lay over?

You note that you purged the gas line, added stablizer/new gas - was it "winterized" properly or was just layed up?

You may have "carb cooties". Even when you take the best of care and follow all the steps to lay up a motor for a few months, carb cooties creep in and clog up the carb jets.

You can try spraying a mix of gas/oil (mixed at 50:1 - don't use carb cleaner or starter fluid) right down the carb throats and see if she will run for a minute. If it does, then either the carbs are clogged or you have a clog in the gas line in, tank pick-up, tank-vent etc - could also be a bad fuel pump bladder - just have to pick a starting point and eliminate the possible issues.
