Motor has no top end....

Re: Motor has no top end....

Ok, Bear. I bought a new connector that snaps on the gas tank. Found out today that the fitting that connects the fuel line from the tank to the motor is one from a mercury that I had on there before. I thought they were interchangeable. I was told they were not. Got one today at walmart for my Meriner.When it gets a little cooler today Im going out to change it out. I hope this fixes things. Because there is nothing else to change?<br /><br />I'll let you know,<br /><br />Suzuki40

Re: Motor has no top end....

Everything is brand new from the carbs to the gas tank. and a large list of others. I guess im going to have to take it to the Mechanic tommarow... there goes big bucks.<br />Motor is starting and running fine,except when I throttle down on it, run about 10 seconds and looses prime in the bulb??? pump it up and it will run great. I can sit there and pump it as im running full throttle and it will do just great for as long as I keep it primed?<br /><br />Suzuki40

Re: Motor has no top end....

go back and inspect all check valves and the tank<br />pickup again. what type fuel tank r u using?<br />have seen lots of NEW defective primer bulbs.<br />can also try this:<br />take off cover and push throttle wide open.<br />as it starts boggiin down, tap on the side of<br />the fill bowl with but of screwdriver. if this<br />fixes, got a bad float. (are floats new?)<br />are check valves in pump new? in right?<br />from left field:<br />once had my local shop sell me the wrong gaskets<br />for the fuel pump. diff. was so small, could hardly<br />tell they were wrong. caused same exact symptoms.<br />good luck,<br />M.Y.

Re: Motor has no top end....

The carbs....do they have the fuel pumps built onto them?<br /><br />If so...the gasket that you mount them onto the intake with has a small hole in it...and MUST be aligned with the hole on the intake as this is where the pulse is recieved.<br /><br />TMD

Re: Motor has no top end....

Hey mellowyellow,<br />I have looked up the part #'s myself to check if the parts I got were right. They are. I have had friends that work on boats all the time come over and check this out. I have replaced the bulb and fuel lines three times. tore the carbs down three times.(with help) 5 well experianced fellas have come over to figure this out. same story every time. Everything related to the fuel delivery is new ( a couple of times). Motor runs like a champ, couldnt asked for it to do better. as long as you pump the bulb.<br /><br />Suzuki40

Re: Motor has no top end....

Problem Solved!!! WHOOO HOOO!!!<br />I had a frind come over today that had a vacuum pump. he put it on the fuel line at the tank and pumped air into it or he sucked air out I dont know. When he did the "T" that directs the fuel to each carb had a crack in it. it whistled like a tea kettle. I must have cracked it putting the fuel lines on. anyway I replaced it and took it out for a test run. Smoooooth as silk. Thanks for all the inquieries and keeping my attention on the fuel system. Ya'll are great and very helpful, Bear and Mellowyellow...Thanks a bunch.<br /><br />This thread is done,Bye<br /><br />Suzuki40
