backfiring through carb and won't go back down to idle

[beasleyxxxxx22]

And ya I'm hoping the intake boot will fix it

 

[YAMAHAULER]

you could try spraying the intake boot with WD-40 while it's running and if the idle changes you know the boot is bad

This might be a stupid question but does it have to be a spring out of a Bic pen and if it does then like which pic pen? Lol thanks

 

[YAMAHAULER]

just one out of a good quality click pen bic is just the most common lol

 

[beasleyxxxxx22]

Well i found a couple pens (not bic) and one spring was longer than the other so I didn't know if there was a certain one

 

[YAMAHAULER]

I don't think it matters try the longer
spring

 

[beasleyxxxxx22]

So I got it back together and just put the old intake boot on it and I used the longer spring I found. I don't think it was quite long enough or strong enough. But anyways it idles a lot better than it did but it'll idle perfect for a little bit then it'll randomly start revving up. Could that be that intake boot?

 

[YAMAHAULER]

very well could be

 

[YAMAHAULER]

try spraying the boot while running with wd-40 see if the idle changes

 

[beasleyxxxxx22]

I did that with starting spray the other day and a couple seconds after i sprayed it, it started revving but but it was hard to tell if it was because of the spray or it doing it by itself

 

[beasleyxxxxx22]

I'll try it with wd40 tomorrow

Bad intake boot. Pull the bowl off the carb and see what main jet is in there too. It should be a 147.5-155 main jet. If its a stock 145 then you are also running lean.

 

[beasleyxxxxx22]

Ya its a 145

 

[beasleyxxxxx22]

Anyone know of any decent jet kits for fairly cheap

 

[austinandtina]

Just go to the atv shop and ask for a 150 through 160 jets they are cheap and Idk what you have done but I run mine with a 155

Get a 147.5 150
you shouldn't have to re jet if everything is stock

 

[beasleyxxxxx22]

It has a slip on muffler and k&n air filter. I haven't added anything to it, it's the way I got it.

 

[beasleyxxxxx22]

Also forgot to say that there was some smoke coming from around the carb when I shut if off after running
