So far thats the only bad thing i've heard about the Pico engine.My 8port runs great.It fires up everytime on the first or second pull even after sitting for a few days.I bought mine for $130(I think)off the internet.I've got about two gallons through it already and it's really making good power.Here's a link for the site I got my engine from.They have good prices and I got my engine in 2 days.
