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 Thomas Bjorkman Falun Sweden .
