Cranked my GX-40 up in the Escapade yesterday. Won't run right. When the engine is stopped there are air bubbles traveling from the carb into the fuel line at the inlet nipple (the nipple is pointed slightly upwards). Got to figure the O-ring on the HS needle is leaking.
Ordered parts today.
I was going to order a nitro HS needle but they're out of stock!
No maiden this weekend!!!
