If this is a 26, there were a lot of guys pretty ticked off with that carb at one time. These 26's were one of the engines that introduced a lot of guys to gas. There was an issue with the pop off pressure set by that little spring, but not many people knew much about that yet. For that reason, a LOT of the OEM carbs were replaced when they would not pump enough fuel - even with a fresh kit installed (the kits don't include that spring!).

This carb, if you defeat that spring loaded mechanism, will not have anything to hold the choke fully open or closed. There's no spring loaded metal ball, or the detent in the choke shaft it engages to hold it in the open or closed position. Point being, if you want to scrap this type choke, it's best to plan on installing another carb.

Second issue is the engine is set up for an external pulse line. No big deal, you just need to be aware. Most carbs take care of this need with a port in the carb flange. This carb flange isn't going to have one of those. So, the new carb (if you go this route) could be adapted by transfering the diaphram cover from the old carb (the one held in place with the single screw?) to the new/replacement carb.

Easy to find/get carb would be from a DLE 20. That carb is 40.00 from Tower. Another might be the Walbro from a VV20, but not sure what that might cost. I'm sure there will be a lot of other ideas. I've never had to buy a whole carb....
