Oil injection motor left 6 mos. Tried to crank. Fires right up and smokes heavily.
You would think it was previously fogged.
Wont stay up. Can adjust rpm lever but will only keep turning while keychoke is pushed in. Once that gas has run through it, it spudders out. I was using gas from my other motor which had a 100:1 mix so I dont know if that gas was just too rich or if the gas line is clogged. Its a friend boat. Any ideas on what may be wrong and what I should check>

Sounds like the normal jets are clogged. I'd
go through the carbs. But first I'd try
some carb cleaners (dunno exactly what --
the longest my Montauk has ever sat is five

Gas line isn't clogged, or it wouldn't run
with the keychoke pushed in (same gas line).

And it isn't the 100:1, it's gas supply.

Try the aerosol GUM OUT. Hose down the carbs throughly. Let it sit a bit, then hose the carbs down again and try to start immediately. If the carbs are varnished, the initial hosing will provide a fluid that will dissolve the varnish. The second hosing will provide something that will ignite very easiy when touched by spark.

Also check/clean the fuel filter.

Personally, I would just disassemble and clean the carbs thoroughly with mineral spirits. Considering how carbs work, I find it highly unlikely that spraying anything down the carb throat alone would sufficiently un-varnish the insides of the carbs in the float bowls. I suspect the float needles are stuck and gummed.

If you're just looking for something to use as starting fluid, WD-40 works fine. With the right nozzle, I could fuel inject a lawn mower with no carb and a can of WD-40, expensive way to mow the yard...
