Hey I had da same prob wid my carb.I pull a piece out of wire out from my wire brush n striaghten it out the best I could n ran it threw my jets to clear all the debree.Then I put the clip on my main jet needle all the way down to the lowest setting on the needle,It idles perfect now.So this might be a good place to start for your carb.Let use know how you make out.

 

$125 is a deal, but why 70mm? 68.5 is stock for the 250 and the big bore kit is 72mm.

You could sell the other 3 on ebay fairly easy I would think.

Some of the big bore quads are 11 or 12:1 and run on pump gas. It depends how well you do your quench. 9:1 is too much with no quench.

 

The only reason I'd go with 70mm is to avoid the need to resleeve the jug. When I spoke with LA Sleeve, they didn't think any of their sleeves would work with the 250s jug.

 

What was wrong with the part # I gave you?

 

I don't know, the guy on the phone just said it wouldn't fit. He did say that a good machinist might be able to modify it to make it work.

 

One of them must fit, because I have one. Call Kustom Kraft. He seemed pretty smart when I talked to him before. He did my big bore kit for the 230.

 

my boy was puttin cross the field on his lt230e other day an it just died like he hit the kill switch,...checked plug no fire,..took kids back to there moms an waited bout 3 days an checked it again an it was getting fire to plug but wouldnt crank, so i figured wed get it running that weekend,..nope! so me an buddy just spent 4 hours messing with it,..it get fire,..then dont,..get fire but then its gone,....not the strongest arc when it dose kinda hard to see,..tryed 2 differnt coils an same with both,...anybody got ideas witch way to go next?????bout ready to haul it to scrap yard!!

 

Pull the stator cover off and check flywheel and pickup coil. Sounds like you may have a loose wire somewheres.

 

That sort of thing happened to me once. It was a loose wire in the power coil in the stator. The vibrations caused it to break.

 

I belive they may have a resitor plug cap. Check inside where the plug goes i belive it would tighten with a screw driver. Also the plug cap screws into coil, give it a turn clockwise.
