Re: suzuki misses at load

You've checked the compression and you say its OK (what are the numbers)? You may have more than 1 issue here. The stumbling sounds like a mixture problem, could be gummed up carbs in need of a rebuild or an air leak like you suggested. Check all fuel hoses and connectors. Check the gaskets on the carbs etc. <br /><br />The water on the plug may be an early warning of leaking head gasket (even though the compression is good for now) or exhaust cover gasket.

Re: suzuki misses at load

thanks for reply. compression (top to bottom) are:130-135-143-143..cold. all plugs are light yello/broun no carbon..worst misses when trimmed all the way in.(down) most worried about water..saltwater destroys engines fast.. if it is the water who make the misses,coud this be exhaust/watergasket layout/leak related? good with a fora like this to discuss problems .
