- Hello, Chris.
- Thanks very much for the helps!
- in my case, ALL the plugs are EVENLY covered by the
- carbon deposits; so as you said, this is the
- carburettor's fault. but I am just wondering
- if the carburettor has leaks of the air,
- the problem should be too much air for combustion.
- but the carbon deposits indicate too little air
- for combustion. as you may observe when you don't
- have sufficient air for burning the wood, you
- will end up with carbon residues.
