LT155 Carburetor replacement question

251 Views 3 Replies 4 Participants Last post by  Cannon51
I replaced the existing carburetor with an inexpensive version. When I put the throttle to choke, it seems it floods and won't start. If I get the throttle adjustment in just the right spot the mower will start, but the engine does surge a bit when running. Has anyone experienced this issue with the cheap carb replacements?

I never put one on a tractor, but I put several on gas engines to equipment I let set to long with fuel in them. The first one was on my old snow blower. I pulled the bowel off and it was a solid mas of yellow gel. The china carb was cheaper than a name brand rebuild kit. I was impressed. All I did was bolt it on and hook up the linkage. One or two pulls and it fired right up. All the adjustments were perfect. Then I put one on a Troy Built tiller and a gas power washer, just bolt and go, no problems. I have also heard horror stories.
I would start with making sure there are no air leaks, such as a torn or missing gasket, and that the throttle linkage is functioning properly (choke fully opens/closes, springs are all in the original spots) then try adjusting the carb's hi & low speed mixture screws.

I bought one for a Kohler Cv15 that I had. I never could get it to stop popping at high idle. I bought one of the Kohler rebuild kits that has the seat in it, rebuilt the carb and it works fine.
I've bought several of the cheapo carbs for small 2 stroke engines when I couldn't get the original carb to work right. A few worked very well, most worked ok and a few didn't work at all. My first option is always to try repairing the OE carb even if the kit is expensive.
