Well here we go, totally frustrated!!!! I have replaced the fuel lines, cleaned the carb and filter inside, cleaned the separator and checked its function. The diaphram inside the carb was not torn and looks good. But for some reason I can't get fuel thru the lines unless I pull off the return line at the top of the pick up baffle and start sucking, then I eventually got fuel up the filter and back thru into my mouth, but I had to suck pretty hard. After that I tried to start and still no fuel into carb???? What pushes the fuel from the tank thru the system???

Ok, so is there a way I can check that its working? Or do I need to get a rebuild kit or ???? I did pull the carb. And took apart as much as I could and everything looked clean, except the filter was pretty dirty. Cleaned it and still nothing seems to be push the fuel.:bigear:

It'll come with instructions, and all hardware.

So the motor looks solid, as far as the paint, it doesn't look like it has been opened. I took the carb off again today and took apart the pump side and everything looks fine. I still don't see how this works as a fuel pump?? But anyhow, I opened the diaphram side also and again all look fine, I noticed that the needle valve under the diaphram, when I push down on the rounded side of the lever, if I push it down equal to the tit on the diaphram, that it doesn't seem to lift the needle enough to do anything. Do you what the needle valves function is?? Also, what is the pulse lines function?? If you know I would appreciate any help. Thanks.
The fuel pump works from the pulse of the crankcase pressure, there is a line on one end of the motor that goes to the carb, this place will be labeled pulse, if your kids are young and you have one of those squiggly drinking straws put some water into it and connect to the line you take off the pulse port - the water should move back and forth in the straw when you press the start button - this action works the pump diaphram to draw fuel from the tank/control/water-fule filter bowl into the carbs, it is possible your carb basket filters are jammed with steel gas can trash and nothing can come thru. If you pour a coffee shop spoon of fuel into each spark plug hole does the motor run on this and then go soft? Next would be to check the rv valve timing to be sure the carbs are in a vacuum at the correct time in the cycle - this will also mess up the pulse so check it first - no pulse go into the rv cover.

Voodoo Man & Keith:
I am experiencing the same problem as Keith: No fuel being delivered to my fuel pump.
In my case, after replacing the crankshaft on my 580cc and assembling everything, when I cranked the engine over, I noticed that NO fuel was being delivered to the fuel pump.
I then disconnected the fuel line to check for an obstruction and when I sucked on it, fuel flowed freely, so, that indicated that there was no obstruction in the fuel line.
In my opinion, since the fuel line is clear, then, there can be only two problems: 1) defective fuel pump or; 2) no suction coming from the engine to activate the fuel pump.
Am I correct? If there are more alternatives, please advise.
When I checked the Threads for troubleshooting this type of problem I found Keith's, which led me to a informative post by the VoodooMan.
Although VoodooMan provided some helpful information, nonetheless, it left me a tad confused, thus the reason for this post.
As pointed out by VoodooMan, he suggested finding the pulse line, located between the carb and engine.
Although I found that part quickly, the question I have rests clarification of the advice.
As suggested by VoodooMan, Keith was advised to: 1) fetch a "squiggly drinking straw; 2) put some water into it; 3) and connect the straw to the line taken off the pulse port.
Now, my question pertains to the specific line VoodooMan referred to: 1) is it the line on the carb; 2) or the connecting to engine?
Voodooman next states that when depressing the start button, "water should move back and forth in the straw."
My next question is: 1) if water is placed in the straw, won't it flow into the engine? In other words, what keeps the water in the straw?
In my case, I like the idea because it will isolate my problem and help me determine whether I should disassemble the RV cover and double check the way I put the RV on.
Albeit I think I performed that task correctly and in consideration that I don't want to go through the time consuming hassle of disassembling it, I want to be sure I try every other alternative.
Any feedback will be greatly appreciated.
