Is this normal oil sheen for a two stroke?



It was running but had problems with idle.
It stopped oiling the water eventually.

Sounds like the float is stuck in the carb. Poor idling could be due to flooding.The sheen looks like unburned fuel exiting from the exaust.

I agree with xsboats - definitely a flooding problem. Could certainly be a sticky float valve or simply too much choke on starting?? Anyway, as long as it doesn't keep doing it, you should be OK!

Well

I would think it could use a fuel pump kit or replace and a carb kit

BUT it is pretty normal even my last of the line 2005 2stroke will turn a 5 gallon bucket pretty nasty in about 3 minutes you just dont see it as much when your on the water

The motor just came back from the shop and was supposed to be tuned and had some parts replaced.
Maybe we just over choked it.

Could be just oil on the outside washing off even. If it doesn't continue it's not a big deal.

Are your certain the fuel/oil mixture you are using is correct? We had a 1963 Evenrude Angler for 40 years and too much oil in the fuel resulted in an oil slick such as you describe.

FWIW...

Looks like you need to have the low speed circuit and the float valve checked in the carb. I think we're building a consensus here

My guess is you have deposits in the carb that are gumming up the valve. As the engine warms up, the valve begins to move more freely, and...you stop pushing out excess fuel out your exhaust. So...yes, it's normal, but you should send it in for a tune-up.

The mechanic came back today and surprise, surprise it was supposed to be tuned up but he didn't recognize the engine so it must have been missed.
He adjusted something on the carb and it runs a lot better now.
Will get full tune up shortly.
Thanks all.
