I have an early HS621. I JUST had it serviced, new fuel lines, tune, paddles, etc. It always starts right up with the first pull and full choke. The problems starts AFTER it warms up. I can use it for about 10 mins then it just stutters and cuts out, regardless of where the choke is. It will start right back up on full choke, then die again in about 15-30 seconds. If I leave it for a few hours (engine cools?) i can then run it again for another 10 mins before it starts acting up again. HELP!!! thanks, xjmllc first post.
