Does anyone know where to get a carb boot for a 5 port. A main has been out of them for quite a while. I tried to fix mine but am still getting lots of oil out of it. Does any other brand work on the Go's? Also, I my boot is leaking and spitting oil all over the place, would this cause the engine to run erratic (sp?)? One more question and then I'm done. I bought this engine used and it has very little pinch left. I have just been using it as a practice engine. What would you reccomend doing to freshen up? Sleeve, piston, rod, and bearings? That would come to around $100 is that the way to go, or is the new generation 5 ports and carbs much better to spend the $ on a new one. Mine had the long lsn and I have no idea as to what generation it is.
