Should the primer bulb have Air in it?

[BoostCreepr]

no matter how many primes, my bulb always has air.. is that normal? I am trying to narrow down a starting issue. stock motor, 990, cpi pipe, NGK, MSD wire. I have spark, but it seems to be no fuel into the cylinder. The weird part is that i had just tore it all down for new bearings, put it back together, got it to fire up and drove it around for a couple minutes, i shut it down to adjust the brake set screws and now it wont fire. it sat for 1 day before i tryed to restart. No leaks, headgasket looks good, no oil from pipe or anything. i just vented the gas tank too.

is the fuel line & carb vent line crossed when you put it together? lol, sorry, that was my coon ass talking. what i meant was, when you put it back together did you mix up your lines & put it back together backwards. the fuel ine has the filter attached to it in the gas tank & the vent line is the other line. fuel line goes to top of carb. vent line goes to bottom of carb. & yes, good luck trying to get the air out of the bulb. it is normal & doesn't affect anything (unless too much air in there b/c it wasn't pumped & primed lol).

i would hope i am not that stupid lol but you never know! I did think maybe my inline fuel filter is backwards.. even though there is no indication what side is what...i will check what you said when i get home. The weird part is that it was running and driving.. i shut it off on my own it didnt stall.

 

[Dreggsta]

well i wouldn't say stupid. sounds like you had a lot going on. the filter really shouldn't matter as you can blow through it both ways. there should be an arrow but you said there isn't so i don't know. maybe open it up & see which way the filter is oriented. the filter screen should be on the side that the flow is supposed to go to.

i make lil mistakes like that too. one time, when i was a teenager, i got my first car, an 81 jeep cherokee. i just did some vacuum tests & i had the fuel line pinched. i forgot to unpinch it & went & test drove it in my neighborhood. well lol, my engine died on the other side of my neighborhood. i pushed it back to my house, popped the hood & saw what i did. unpinched it & it fired right up. lmao, talk about feel dumb. i coulda drove it back home.

Try a plastic bag over the intake to choke it, or a short squirt of starting fluid..?

Is the plug wet?

the vent line goes on the primer bulb side of the carb.- its the fitting attached to the white plastic plate. the fuel line goes to the bottom of the carb. when the bulb is pumped, it should have about 2/3 to 3/4 fuel in it. The primer bulb- all it does - it fills the carb with gas and purges out the air. pushing the primer bulb will not put 1 drop of gas into the motor if the carb is operating correctly.

So i'm going to say it was a fouled plug. I pulled my NGK out and there is some black carbon build up on the top of my piston so i guess im running rich. When i fired it the first time i had the brakes too tight and when i tried to drive it was dragging hard so the buggy was barely moving.. guess i flooded and fouled the plug.. fired up with new plug. My bad?

 

[Dreggsta]

lol, at least it was a cheap fix.

 

[BoostCreepr]

Well new issue, im guessing messing with the carb trying to get it to start has my buggy running like shit lol. It starts fine and idles, a lot of smoke on accel and while idling if i blip the throttle and it comes back down it slowly bogs out and dies. Which needle needs my love?

 

[andyken]

Sounds like the low is rich...try resetting both to factory settings.

Also count the turns in to see where you are @.

 

[BoostCreepr]

i have done that, guess ill lean it out some more. I was thinking since i reved it up before it dies that it might be the H screw

 

[Dreggsta]

Yeh the low sounds a bit rich. Blipping the throttle affects the lsn & holding the throttle down affects the hsn.

Gotcha, Thanks for the info. ima get this sob purring lol
