Mariner engine problem

[champion]

I ran some staybil thru her and same result! I guess next thing is rebuild carbs?

[Embrey]

could be many things...carbs, pump, timing. if you dont get it lined out, i can fix it.

Yes like he said could be a long list,from fuel pump to timing and everything in between.
As for stayble its not an quick fix,takes time to remove and lube, I use it as a preventive,not so much as a fix,but can in time remove a lot of built up soot and somewhat lube and clean carbs.Will also smoke more at idle while doing so,but smoke is generally from removed soot not from rings,burnt valves etc.
A bill for fixing from someone else can beat one ruining what one has,if you have gone thru all the normal steps.
