Looks for some suggestions. I have dual 717 sportster 1800 89' if the year matters. I have 2 brand new fullbore top of the line engines. Less than 1 hour on them. Ran fine for like 10 mins on water and one engine just shut off. Took is home and checked compression I have 150 PSI on each cylinder, see no to leaks and everything is still hooked up. I can start it but it has no power when it runs. Its missing that seadoo/skidoo raspy pining you normally have. I can tell its not spinning fast enough even and idle give it gas it dies. To me it seems like fuel or timing. The carb was rebuilt and I cleaned it before I put it back on but those single mikuni's with the accel pump have passages that are hard to get clean a clog very easy. The plugs look good with no extra gas to black. I do have 40:1 in the tank plugs the oil injection for the break in. I do have spark at both plugs and spark plug wires look good.
Any help will be great..
