Alright, so used a 22LR shell to make a brass insert for the carb bowl and tie it into the enricher. Cold start ain’t happening. Linked and sync’d all the carbs, installed screws and nuts and tossed the sheet metal tabs. Runs like the carbs are dirty but I have ultrasonic cleaned and blew out with air. Made sure all the passages were good.
Ok so for the enricher system. The newer style mod will not work. The intake is venting a specific amount of air through the enricher needed to run. Plugged off, runs like garbage. The carb flap openings were designed for this amount of vacuum leak and still work.... So, I am thinking I am going to put some older style carbs on designed for flapper choke system I can toe into the key switch. With these carbs I should be able to close the enricher hoses going into the intake.... hopefully.
Jerry, I included a pic of the “wax ball” enricher valve and will explain this thing. So there are two 3/8” ports in the intake that the hoses go to the enricher and vacuum the outside air. When the throttle flaps are closed this creates a vacuum and pulls fuel into the intake to start. Once running the enricher heats up using a heating element. In turn the wax ball inside the needle valve begins to expand and push the needle into the seat cutting off fuel enrichment. This I guess was supposed to be a step forward, but I view it as two steps back.
I did order a set a set of running carbs off eBay just now, hopefully going old school fixes our issue!
