[QUOTE="Ster1, post: 124446, member: 20800"] Oh boy so close now! So a couple thoughts, if gas is dripping out, that’s a float valve problem. You might get lucky just tapping the carburetor with a screwdriver or something you can get in there. Maybe that will get the float to seat. That’s no likely, but worth a try. Otherwise that carb has to come back off and the float valve cleaned or replaced. You’re going to want to take care of that leak before trying to start it again. The volume of fuel is going to be ok. So let’s talk timing! You got your internal timing set? Your crankshaft gear and camshaft gear timing marks line up? I can’t remember if you took the engine that far apart… maybe you didn’t. With cylinder 1 (the one closest to the water pump) on TDC compression, the distributor rotor points to the lead for the #1 cylinder. Bring the engine to to TDC 1, take off the cap and make sure the rotor is pointing to the wire that goes to 1. Firing order of this engine is not normal. Normally a 4 banger will be 1,3,4,2 but the Kent is different at 1,2,4,3. This would be in your manual, which I’m sure you’ve combed over. Open up that throttle a little, and don’t be afraid of giving her a little ether on that first start. With oil and stuff in there, those plugs sometimes have a hard time firing that first time. It’s going to smoke at first. Alot. Don’t sweat that, it’ll clear up. Be ready to disconnect that coil should the rpm’s shoot up for some reason.
