Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a Honda HS521 snowblower that starts easy/well, but after a minute or so runs rough, backfires and eventually dies.

I can keep it going by moving the choke in/out to keep smoothing how the engine runs, but even that will only work for a short time.

I have replaced the plug, used clean gas etc.

Any suggestions ?

Thanks.
