This has the surgical type fuel lines running from under the carbs to the Block outside the piston. The lines blow off from the side of the block.
Do I need to ziptie them on there or what;s going on...?


Motor is running good. won;t idle well after lines pop off. (Duh)
Help.

I have the same engine, but never had that problem. Are you sure the hoses are routed correctly? Try replacing the hoses with new ones that fit tighter on the barbed fittings.
