Default Re: Yamaha g8 low engine rpm till warms up

I will check to see if I can get a tester at the parts store when I take back the compression gauge. I checked the primary coil with a known good meter and it has 4.6 ohms that seems ok with what the manual says for the g9 but I am working on a g8 but can’t find the exact manual for it. It also shows to test the secondary coil by going from the red white wire to the spark plus cap. I don’t get continuity at all there. Maybe that’s the difference in the j38 and jf2 coil? I have never used a spark tester do I just compare the light strength from when it’s running rough to when it’s running good? The small ground cable is spliced to ensure a good ground to the starter generator. Thanks for the help so far. Hope you guys keep helping with this issue! When I disconnect the fuel line it pulses fuel out not with a lot of pressure but I would think enough. I could pull the carb off and ensure the bowl is full when it’s running rough if you think that would show it’s getting low fuel.
