I have removed the choke cone and stand pipe as they were both broken. The base of the stand pipe appears to be a 3/4" square with two 1/4 circular pieces standing where the pipe broke off. How hard are these to remove? I made a tool to fit in the slots, but it didn't budge with what I would consider a good bit of force. Does the jet nozzle that screws up in from below have to be removed? This also seemed pretty tight. I read through the archives and it seems the venturi has to be removed with a special tool/puller. Is this something that can be fabricated/machined? Is there a drawing or photo of these tools available? Does the wishbone shaped fork that raises the choke cone need to be removed? If I could remove the venturi and the base of the stand pipe, I think I could fix this carb using parts from the Filling Station. I have the repair manual and parts book etc., but they don't go into enough detail/step-by-step procedure for my level of confidence. I am not the sharpest tool in the shed, but I have rebuilt a few carbs over the years. Any advise, tips or counsel would be appreciated.

It takes a special square socket to remove the standpipe. The venturi is removed by another special tool. It has a substantial base that sits on the top flange and has a hollow center bolt to fit over the standpipe and then a "C" shaped piece that slips into a slot in the end of the bolt. Retracting the bolt removes the venturi. If you want you can break all the parts, clean the threads (takes a special tap or a lot of scraping with a dental tool to remove the remaining threads) and put in new parts. Still need the special socket to install the new standpipe. Oh, yes you need to take out the wishbone shaped fork to remove or install the standpipe. There are a few techniques that are slowly learned to remove some of the parts.

Or you can send it to a rebuilder that has the tools and knowledge to take it apart and put back together correctly. I suggest sending it to either Skip or me instead of messing up the parts and making more work for all of us.

Thanks for your prompt and courteous reply. I think I will take your advice. I have your mailing address from a previous post. Perhaps after the holidays we can make arrangements.
Regards,

Joe
