Fuel leak problem

[Stephen perkins]

So I rebuilt my 4.6 new sleeve new piston new crank new block and it turns over really easy but now it spitting fuel out of the front bearing does that mean I need to replace the bearing? Any help is greatly appreciated

usually the front bearing is sealed, so leakage should be minor if any, is this the same bearing from your previous or did you buy a block with bearings already in it....
sorry to say but you could have gotten a complete for what you have put into this current one.....

+1 jam. For all those parts replaced I'd have just picked up a new motor too.

Seen a few threads the last couple days about fuel coming out of where it shouldn't be. Maybe time to review some 101 articles. Just take a look at the area where you are sputtering fuel...the answer lies within.

Well I think it was after run oil I had on it coming off because it stopped so I finally got this thing runnin broke it in had some trouble with the tuning but got it close. Took it to a bashing spot got a tank through it ran it out. Put more fuel in it started her up when to hit full throttle goes 5 feet and dies tried 6-7 times. Not really mad just glad to get the thing started and runnin finally.

On a brand new you should not be "tuning" ,get it where it will run and go on the ground in big circles easy o the throttle for the first few tanks while the carburetor is set very rich and just get the just at or a bit above 200 degrees and do this several times, then and only then should you attempt tuning and getting it leaned out.....when you shut it down always remember to put the piston at BDC while it cools, it helps to make a mark on the flywheel at the bottom of the pistons travel so you can just rotate it there while it is cooling down...
