John Deere 826 snowblower with Tecumseh HM80 issues

I have a late 80's early 90's vintage Deere 826 snowblower with a Tecumseh HM80 engine.

I am having issues getting it to run smoothly. It misses at idle and backfires out the exhaust when coming down from full throttle. When it misses, you can hear a ting ting sound in the muffler.

I have replaced the solid state coil, carb, plug and fuel line. I have pulled the head and checked valve clearance (lapped valves as well) and cleaned the combustion chamber.

What can I check next? I looks like the muffler gasket needs replacing but can that cause my issues? I have played around with the high and low speed setting on the carb but I still cannot get it to run smoothly.

I have good strong compression as well.

HELP!!!!

Those motors will pop to an extent. Its part of the compression release, that cracks the exhaust valve open a slight bit on the compression stroke. But most likely its running lean. The ting, ting sound is the muffler expanding, from the lean condition and its starts to run hot due to the lean condition.

Thanks for the reply. It still tings even if I fatten it up to the point of wanting to die.

Clean and rebuild carb. Make sure you clean all small holes in carb and jets. Then adjust when running.
