after reading a lot of great and informative topics here, I think im just going to rebuild the carbs,vro,fuel pump and replace all the fuel lines. The question I need to ask is it ok to replace the old fuel lines (i believe they are plastic) with new rubber one's? I gave a better description of what the engine is doing in a previous post, to no avail so im hoping by taking other topics and applying them to my prob it will solve the issue.
