Questions: Hi, please send me the dimensions of the following carburettors as per your part numbers #923804-A; #647744, A17854 and #923806. I have built a 1953 CJ3B motor in a 1949 CJ3A chassis and body (Tub, fenders and grill)
Question By: Gerhard Genis on Aug 28 2022 4:31 PM
The F head engine will not allow you to close your hood. The carburetors will be too tall. Email mike@kaiserwillys.com to try to help.

Questions: I just went through a YS and have a question about the port on the right side of the venturi with the float bowl facing away from you, not the one with the check ball and weight but across from it, there is a divit that looks like a question mark and a port, air does not blow thru it and I haven't seen where it comes into play downstream in the venturi,what am I missing.
Thank you
Aaron

Questions: Hi Mike !!! I have a YS carb I purchased from K&W --- I can't get it to idol without the choke engaged and throttle out --- fuel pressure is good.
Your thoughts ???
Regards
Jerry

Your engine is probably generating poor vacuum. You should be 20 pounds of draw at idle once fully warm and no longer choked. RPM around 475. If you dont have this the carburetor can leak or die because fuel cannot discharge out of the carb properly. I would check your cold valve clearances and use a pressure gauge to check it too.

If you have an M38 with a side draft then yours should be stamped 637 on it or have a tag that has those numbers. Please email mike@kaiserwillys.com to help. Thanks!

Questions: Hi
I live in Sweden and I have a nice M38 (flat fenders) with a Carter YS 637 carburetor..
The carburetor flood the manifold and I have tried everything.
Can I send my carburetor by mail and have it rebild with "function guaranteed".
I have had the M38 for 10 years. Last summer this problems started. The engine now starts fine run smooth for 30 seconds then start coffing and stops.. When I
remove carb there is liquid petrol(gas) in bottom of manifold.
Best regards
