I believe the spark is weak in my 91 SPI (580).... Main problem... go for a ride ,maybe a minute, maybe an hour, slow down to an idle, stalls out, won't restart. Lots of fuel, plugs are wet from trying to start, vapour in the air & nose! Can't really see a spark when plugs are pulled & grounded.... reload on trailer and start investigating in garage. When plugs are pulled a SMALL blue spark can be seen/small gap. What's funny is I tried to short myself between the high tension plug wires and block, only to recieve a small buzzing sensation! Don't these CDI units produce a 'knockout' hit? Have cleaned all grounds, new plugs, disconnected/reconnected over-rev limiter(no change). Finally pulled a coil from my snowmobile.... same small, small, blue spark????
What else can I check/verify? Please, this is not a fuel problem. I know what you're thinking... blue spark, hey... not your problem.... but why would the energy produced at the plug wire not place me 6 feet in the air? BTW... same systoms either spark plug. And again... blue, not yellow!
all thoughts welcome...

Sandy
