1979 85hp Evinrude running on three

[otislav]

motor running on three cylinders. Plugs are new and have spark. spark jumps 7/16 with the spark tester. Compression is good. I rebuilt the carbs last year but it ran good for a while after that. Is there an easy way to check if fuel is getting to cylinder.

got it fixed...took the carb off from the troubled cylinder and found a small piece of what looked like gasket material in the orifice on the float bowl.

Sorted .....probly should give the other carbs a bit of a look see too

Just rebuilt them last fall with OEM parts. Thought i was being very carefull to keep them clean but a new piece of gasket may have flaked off somewhere, or a chunk of the old one I scraped off. Running good now.
Thanks for checkin in on me.
