The one I was helping a friend with the rope pulled out on the second break in tank and then to add insult to injury the spring broke during reassembly. Just like PeteOz it is sitting in a box and we are running the Mach till the tiger drive becomes availble.

Oh yeah, they wanted him to send the engine back for inspection and want $50 for a new pull start..................... and yes I have used pull starts on several different types of motors and never had the spring break.
