[Boo_69]

you might want to check the filter on the fuel pingel. just a couple screws to be sure that those filters aren't plugged with any crap. :thumbsup:

 

 

Oh welcome to the HQ!!!!!!!!!!! :biggrin:

That particular topic has always been a little confusing to me too but from what I've heard (stock) you have one bowl with a brass tube inside and the other does not. Hopefully someone else will chime in because BOTH of my carbs have the tube and it's ran fine for years...?? :shrug:

just do one at a time

i guess im a little confused right now anyway......it ran fine up until a couple weeks ago. then i noticed there wasnt as much power and the exhaust wasnt coming out as strong on the right side. thats when i had the carbs cleaned... the only thing i think will answer my question right now is doing a compression test which i should have done before i pulled the head off... so im going to try and get a compression tester by the end of the week. because i dont think it has anything to do with the jets or reeds or any of that right now.....i could be wrong.

if you never changed your jetting from riding all summer then your jetting is for sure a reason why it runs like shit. i'm not saying to not do a compresion test but if it wasnt changed i would do that before digging into anything else

doubt it is compression either if the pistons/cylinders looked good.

Sounds like fuel prob.

Pull one of the fuel lines off the carb and open the petcock and

see if the fuel flows. If it doesn't check for inline filter clogged or

petcock filters clogged.

If it does ...........

You said it is stock. Probably the fuel lines are original too.

It is possible for some of the rubber to erode out of the inside of

the fuel line and clog up the needle and seat as well. Especially

with all that oxygenated fuel you get at the pump.

yeah a compression test is an easy way to ensure things are still good or not but keep in mind, carbs can and do fall out of sync frequently so that, the choke tube, and the carb slides in the correct sides are likely candidates for the fact that it won't even start now.

a bit of an update. just did a compression test and both cylinders are right around 100 psi after a few kicks. now i pulled the airbox back out to look at the carbs. they seem "synced" to me and the beveled side of the slide is pointing towards the air box. they are also both getting gas. i did forget to connect the choke tube so i did that. would the "reeds" have anything to do with the problem? i guess i dont understand what they do or how to see if they are the problem.

check to see if both spark plugs have good fire,maybe even put some new ones in.if you can spray into the carbs and it will run off that means you are not getting fuel to the combustion chamber one way or the other from the carbs.you say the carbs are getting fuel,check to see if there is any fuel in the float bowls.

Ok so your compression is ok even though it doesn't sound like you did it correctly, you need to continue to kick it until the needle stops moving and you also need to hold it at full throttle the whole time you are kicking.

 

Besides that, yes your reeds could have something to do with it also, if you want, pull them out and make sure they are not damaged in any way and also make sure they sit flat against the reed cages. If they are gapped real bad then that can be a small factor also.

 

You said the choke tube was disconnected... that could be it right there though. Not having the choke tube connected make them nearly impossible to start and even if they do they run like crap. Did you try it after connecting the tube?

[laidout20]

well seem to have got it fixed..... im not sure what it was but now its running strong on both cylinders. starts right up since i hooked the choke tube back up haha. im anxious to ride it now! thanks for all the backup im sure ill be back for more help. now i can start working on my truck again.

Make sure you use Cold rated two cycle oil in your mix. Regular oil can break down and cause a whole lot of starting and running issues.
