One more thing before I buy a new carb, on the needle there is a clip at the top with several different places you can place the clip, would that have anything to do with the idle or the plunger not going all the way closed?

I did notice the needle on the new carb is longer then the stock one, I'm thinking that might be keeping the slide from going all the way down. Does this sound like it could be the issue? Can I use the one from the stock carb? No that cant be right, it should be longer since the carb is bigger.

How far open is the slide being held? If it is not a lot then yes try moving the C clip on the needle, at this point it can't hurt and you can always put it back where it was. Moving it up on the needle should let the slide drop further closed iirc.

Place the clip on the middle one. If it hesitates on throttling then drop it down one .

here's a pic the idle screw on the right side is unscrewed so the other end is not holding up the slide. It came on the 2nd slot down from the top
the clip is on the middle one. It came on the 2nd slot down from the top

Ok the slide is supposed to be up a little like that, if it sealed completely you'd get no air into the cylinder. What size pilot jet are you running?

When it was running at 3k. When I gave it some throttle it just bogged down.

Yeah it only fits in one way. left side inside has a small pin that sticks out and on the right side has the idle screw. Left side of slide has a small vertical grove cutout for the pin to slide in and on the right side has a bigger grove that goes maybe 1/4 of the way up from the bottom of the slide for the idle screw.

My next day off I will try upping the jet size to 120 if no luck I will go down. I tried 110 and 115 with same results. Maybe mess a bit more with air/fuel screw. Maybe I have a vacuum leak somewhere. If all fails I will keep stock one on for awhile.

Could be a vacuum leak. I know this was asked already but what size pilot jet (slow speed) is installed?

carb
you know you tried a lot of stuff and keep having the problem.... the plunger has to go down as in the pic... and the needle has to go into the jet.. to seal it off... if it is too big for the jet.. or too high it sucks too much gas.... as I think you might know this... so where is the original jet that came with the carb... ??? the engine is getting too much gas ... does the needle fit into the carb idle jet??? and the cable is off... the idle screw is out all the way... then do this.. and see.. if the screw is not holding the plunger up.. and the thing starts up still and revs up... the idle plunger needle is too loose in the jet causing it to suck up too much gas,, move you c clip up all the way to the top... this will let the needle go into the idle jet more.. and cut off the excessive fuel.. you have to get the needle to cut back the fuel..

Thank you, it has a 115 in it now but will try the 95 that it came with and move the clip to the top and go from there. Wont be able to try that until Sunday (Day off)
