Tips to fire up a fresh Z?

Oh, my life sucks! I can't get fuel to blow past the pump...............................back to the drawing board.

Have either of you two ever heard of ether/starting fluid? Geesh!

This has worked with no problems on your Tri-Z? I really wasn't concerned much with getting it to fire as much as making sure the fuel pump worked.

Thats what I do on my trike when I run out of gas and fill back up, its much easier then pulling for an hour and it gets the gas flowing.

EDIT: I said that to try to help you get the gas flowing because in one of the previous posts a guy said the use engine pressure to operate. Hence the starting help. Worth a try, and good luck!

Does your pump seem to pull the fuel right to the carb when kicking it? Mine doesn't, and somehow I have to figure out why. Do you have any suggestions that worked with yours? I can't see anything that isn't right with the installation, and it has me wondering if there might be something clogged up in the diaphrams. Does your have the filter in the bowl?

Did you open the fuel line first? If its open and you cant blow gas through it, there is a problem with one of your vavles, or both.

The pump does not need primed. It should pump fine with each kick of the kickstarter.

The diaphram is in the back of the pump. when vacuum draws it back, it pulls gas through the valve on the left into the back of the pump. When the diaphram moves forward its pushed out through the right side of the pump to the fuel line to the carb. If the one way valve on the left side is not working, it will simply push right back towards the tank, and just pumping the gas back and forth.

The valves are not complicated. They are a dime sized plastic disk held in place by a rubber plug. It should be obvious which direction they will open, and which direction they will not. The left side should have the dime sized plastic disk in the back. The right side should have it in the front.

Thanks to everyone's suggestions from experience!

Tim and Chris came across some important things that "might" be an issue with mine. I think my on/off/reserve lever might be assembled upside down, thus not allowing fuel to flow out of the bowl. I'll look it over close and compare to some pics that Chris sent me. If that isn't the problem, then I'll have to use Tim's explanation of the pump and how the rubber plugs work.

I'm hoping it is simple like the petcock assembly, and I really think that's the issue after looking at Chris's photos he sent me.

Im going from memory, which doesnt work well these days, but i think the lower gas line on the tank hooks to the upper input on the fuel switch. If they are backwards your fuel switch will just be reversed and on will be reserve, and reserve wil be on. If you think this might be wrong, and you might have them switched, just fill the gas tank above the reserve level and it wont matter which position the switch is in.

I "think" that my petcock assembly might be backwards, and not allowing fuel past the bowl. Not sure yet, and will look tomorrow to confirm, but I remember yesterday that Reserve was stamped on the top side when it was assembled. Chris says that his says On is stamped on the top side of the petcock. I have company to deal with right now, but tomorrow I will get back at it!

Mike... I hope I'm not giving you wrong info (this stuff is all new to me) Right now I have those rear gaslines hooked up top hole to top hole and bottom to bottom. I did have them hooked up like Tim said but changed them cause I wasn't sure they were right. The more I think about it the more confused I get.

This is the current way I have it. I'm thinking the lowest hole in the tank (on the bottom) would be reserve. I have that hooked to the bottom hole on the left side of the pump.

I'm not having any issues with getting fuel past the pump and into the carb with the way the switches are positioned right now. But then again I have 2 gallons of gas in the tank. I hope someone could correct me if I'm wrong.

What confuses me even more is I'm not sure what side of the petccock switch is the actual indicator????

I'm going to have to install a breathalizer on my computer for days like yesterday! I should know better than to SUI (surf under the influence).

Thanks for everyone's suggestions and tolerating my ramblin' on. I'll get this whipped, one way or another!

HA!!! Welcome to the club... Thank god for the "EDIT" button.

I noticed yesterday after running mine a few times through the heat cycles that the bowl on the bottom of the pump vibrates loose and start to leak again. WTF?!?!?!

[GoodKarma]

Well, it runs and didn't blow up! But, the fuel pump doesn't seem to doing shyte! THere's a trickel of fuel that comes out of the carb side, but not enough to keep the bowl of the carb filled. I can fill the bowl on the carb, and get it to run for about a minute. Tore the pump apart AGAIN, took the plungers and put the left one on the right, and the right one on the left, just for something to try. Fuel pulls up to the pump, but not coming out the carb side. Anyone nearby to come look at it?

Can anyone remind me where that rebuild kit was available for the pump? Maybe something on mine isn't fitting good, and I should buy another kit. I have done a search on Dennis Kirk, but not finding that kit that used to be on there.
