r/HondaActy

My 93' Honda Acty HA4 needs its Carburetor Diaphragm replaced. The diaphragm's vacuum seal is no longer keeping the fuel at bay and is causing idling and air intake issues.

I've ordered Part 16046-PN3-005 - which I thought was the correct Diaphragm Replacement Part, but now that the part came in, the part does not line up... So I'm at a loss! Is there a different Part Number I should be looking for? Does anyone know the Keihin Part number that I might be able to source? Any help is appreciated!

I’m still having issues getting my 1995 Honda Acty to start. I’ve already replaced the fuel pump and still nothing. I did pull the plugs and they were a bit dirty and I didn’t have any new plugs on hand so I just cleaned them and put them back in and still nothing. They did however smell like fuel so I know it’s getting fuel into the cylinder. I just did an oil change today as well. I did have a weird occurrence while hooking the battery back up where the coolant fan kicked on and stayed on until I disconnected the negative terminal. That was the first time I’ve heard it turn on so idk if I was just freaking the truck out or what but it’s not doing it now. I’m definitely going to order some spark plugs and wire kit and just replace them anyways.

Any and all advice would greatly be appreciated!

I believe its the coolant temp sensor, but i cant find it anywhere
