Fresh BUILD! Won't Start!

[AdrenalineJunky]

Fresh build and when I first started it, it was trying to run but carb started overflowing out side overflow. I took it apart cleaned it out and never got it to try to run yet. I checked spark and it isn't the fattest but it is there. Took other carb off and cleaned and no help. Now it started overflowing out bowl.

I have orange and black connections at coil. Is there a ground wire that comes off coil to frame/ground?

 

Well it isn't getting gas. Sprayed carb cleaner just to see and it fired right up. So Y am I not getting gas from carb to cylinder?

What kind of build? Frame and all? The coil has it's own ground. The two tabs that the coil mounts to need to be bare metal.

[AdrenalineJunky]

Yah down to bare frame. Well i'll have to scrape paint off that should give stronger spark. I was thinking I put reeds in wrong. Taking them out and I don't see any difference in how they can go in. They are Delta Force 2 reeds and cage

 

So is there a certain way they need to go in????

[Jereme6655]

okay....lets start simple.....NO MORE STARTING IT WITH STARTING FLUID!!! starting fluid doesn't have oil mixed in with it so you're basically running it with no oil = bad BAD thing.

 

but since you did and it DID start real quick...that means you've got spark...

 

but you said you aren't getting gas........don't take this the wrong way....but ive been fucked over by it before.... Is there enough fuel in the tank? Is there ANY in the tank (if there is but its low...then try turning the fuel valve to reserve). IF its got plenty of fuel in it then pull the fuel line off the carb and turn the fuel valve on and see if its flowing fuel out of the fuel line.... if it is then your carbs are definately goofed inside. when you cleaned them out did you maybe mix up the slides? the slides CAN go in the wrong way into the wrong carbs...

 

let us know...

[AdrenalineJunky]

Definitely have plenty gas in tank. Mixed fresh gallon. Definitely getting gas to carb. I was thinking about

Taking float and fuel valve out and cleaning since I was having overflow problems. Could that be the problem? Also, what about the reeds? Do they go a certain way? I looked and doesn't look like it matters.

 

Slides are definitely in right also.

Slides are definitely in right also.

carbs could be gummed up or you need a carb rebuild kit or you have very low compression . Your better of to put your sock in the tank and use it than that starting fluid .

[AdrenalineJunky]

There not gummed up because I have had them apart cleaning them. I am thinking there is some dirt in fuel valve passages. I had the carbs sitting on the back porch on my tool cart while I been building the motor in my extra room as I don't have a garage at my house. Well mud daubers decided to get into a couple of the vent lines and such on the carbs and the fuel inlet of the 1 carb. I thought I had it all cleaned out because I blew out all the passages and such. After I did clean the one carb then the float started sticking. If the fuel valve had some issues would that not let it feed to cylinders?

[bansheesandrider]

Did you get the float bowls back on the correct carbs? They are different.

[AdrenalineJunky]

Yeah I only work on them 1 at a time. Are the Moose rebuild kits alright? Basically need the seat and needle correct? I need to go ahead and check float height also.

Can someone confirm my question about the reeds going in 1 way or not? VF2 reeds.

Well I still cannot get it to start. Few things to add.

Compression is 145psi in both cylinders with 20cc domes. Has spark and I went through carbs checked float level fuel valve and seat. It just isn't getting

Fuel to damn cylinders. I don't know what to do.

if they got really mudded, then there could be more passages you are not checking, like the airscrew and airjet holes at the mouth of the carb. did you put the choke tube in the right spot? directly across from the back of the choke to the same place on the other carb. if you stick that on a vent tube, if possible, the right will pull ir from the left, and maybe pull a little vacuum on the bowl to slow fuel to the left. now, you say you have spark, but not the best. that's probably the big problem right now. weak spark can fire a well atomized fuel, like the carb cleaner, but have a hard time igniting cold fuel. (hence the choke needing to over-richen) another thing is the slide height. too high and it won't pull fuel while you are kicking it (unless you take the filter off and hold your hand over the carb)

check your pickup gap, and make sure you put the screw back on the cable retainer that attaches the wires to the back of the timing plate. that is your engine ground. you can use a sparkplug box flap to set the gap. another thing that will simulate weak spark is the keyswitch wires loosing connection. it will only spark some. same thing with a weak stator, which will spark every 2-3 kicks. make sure the plugs are clean, and not with a wire wheel.

[AdrenalineJunky]

I checked the spark after sun was down and it looked alot better then I had thought. Pickup gap

Was set with business card. Maybe I do have slides up too high. I blew air through every passage and never

messed with choke tube.

[AdrenalineJunky]

I never mixed up bowls but at this point previous owner may have.

The carb with choke has tube running up into bowl. This is killing me.

[AdrenalineJunky]

What about the needle jet? The 1 that is under the main jet in carb body. Not

The 1 with the clip. Doesn't it have a bunch of holes in it that allow fuel to flow through and is it pressed in?
