351 W stops after being shut off wont start

In Lake Placid Florida. 10 Miles south of Sebring.

Thanks,

It just acts like it is not getting gas? It initially start and runs like a champ but does not like to idle under 1,000 (smooth not like bad valves)    When shut off she refuses to start. Strong battery all cells good 12+ volts.

Thanks,

Thanks for the reply. I am almost positive about the flooding. With the throttle advanced and in the neutral position (gate pulled out) she still cranks. Spark arrestor off and no choke showing. ( I even tried to choke it manually with no results) I thought of a stuck float? Bad fuel pump? Have replaced the ignition switch, coil and put a new style fuel water separator on. It does have Electronic Ignition conversion. Looks like dual pick ups on the Dist. Lobe.

It runs perfect, but does not like to idle below 1000 RPM. Timing? 351 PCM Windsor 1986 with 675 hrs.

We love the Boat and just a good old Cheesehead in Florida!

Coil is warm. And NEW. Same problem as with the old coil. It has electronic conversion.
I will check the spark. But why would it start and run like a champ then after setting for a few minutes refuse to start?

Thanks,

Bob,
It's great that you found CCfan and welcome. The normal request is for pictures. We'd love to see some. A diary entry would be great as well.

Make sure it's not flooding. When you shut it down, look down the throat of the carb. (remove the flame arrestor). If you see gas dripping, the carb most likely needs a rebuild. If it is floofing, in the short term, when starting open the throttle almost all the way. This allows more air and will overcome all the gas.

Since you say it won't even start with starting fluid, then you are correct that there may be an ignition problem. Check for spark and get back to us. Does it have a point set in the distributor or an EI conversion?

BTW, please get rid of the starting fluid. You are ruining your engine. The stuff is a strong solvent and washes the oil off the cylinder walls.

I have a 1986 Correct Craft Martinique that starts and runs strong. After I shut it down it will not re-start. Even with starting fluid! It does not act like it is flooded.

Replaced coil, ignition switch and put in modern water/ fuel filter.
