So last summer I took the 90 superjet 650 out to the river and it spit and spat when it ran so I put it away for the season. This year I rebuilt the carb and while the carb was off I noticed that the gasket above the reed was busted. I took apart everything on the intake side, cleaned it all up, and put in all new gaskets from the top of the carb to the reed valves. Last summer I redid all the fuel lines and cleaned out the fuel tank. Right now the choke butterfly is out and I have a nipple where the choke line used to be (primer kit).
Yesterday I defogged it from winter storage with the new setup installed and it ran ok. I took it out on the water and it wouldn't start at all. After priming it with 3 squirts it will ignite one piston but nothing after that. Smoke it coming out the carb telling me that the single ignition is probably backfire and that I need to lean out the mixture? I'm hesitant to do that right now. I pulled the plugs and the front cylinder had oil smoke while the rear had nothing. I'm really perplexed as to wtf is happening at this point. The carb settings were stock before the rebuild, and I returned them to stock after the rebuild. I'm going to do a compression check to see if the air leak at the reeds destroyed a ring or ruined something internally.
Any ideas or suggestions? I thought it was a fuel delivery issue, but everything on the fuel delivery side, except the vent valve, is either new or rebuilt. :scratchchin:.
I'll post compression numbers. Any help is greatly appreciated!
