Ok guys, maybe someone out there can help me out. I have two 5iveT engines that are both having similar problems. I can only get them to run while giving them about half throttle, as soon as I let off, they quit. I have tried new diaphragms, swapped carbs (including 2 brand new ones), reset factory needle settings, changed fuel, pressure tested the engine for air leaks, spark good, changed filter and fuel lines, air filter good, I am running out of ideas, as you know there is not much to these engines but I can't seem to figure it out. I have looked in forums but so far have not found anything that seemed to help. I'm still not convinced its not a fuel problem and I am looking at swapping in a whole new tank, fuel, and lines to see if that helps. Both engines appear to be ok (IMO) but maybe they are toast? They both have compression and show only minor wear marks on the piston/cylinders. I have always kept filters changed every run and they have never sucked dirt or sand. It could be they just need more tuning? In the past I have reset factory needle settings and always had them start first or second pull. Both engines have only maybe 3-4 tanks ran through them. Also when I checked the engine for leaks I did not check the manifold, it looks fine but I don't have another to swap out yet, so that is a possible fault. Surely someone out there has had a similar problem? It must be something so simple I have overlooked? Any advice would be much appreciated, thanks guys!
