50ELPTO not getting on step

[worktoeat]

I am having trouble with the motor not getting out of the hole. It is a 2008 50 hp oil injection 2-stroke. Any suggestions? I have changed fuel filter and the complete fuel line.

Report the results of a compression test.

No compression test done. Motor sat for about a year and a half. Thinking it has something to do with oil injection sensor

OK then---If it sat all this time then the carburetors might be plugged / gummed up.---Time to take a look.

I've cleaned carbs and changed plugs and fuel lines and filters. Fresh gas in tank. Engine starts and runs fine. When I get on it to get out of the hole it will shoot out then fall on its face. I can run all day at what seems to be half speed and never will engine die or miss

May not be running on all cylinders. Using insulated pliers disconnect one plug wire at a time at idle to see if engine RPM changes.

With all the work done allready but not mentioned , you must have checked for spark on all cylinders !
