Hi, this is my first time here, I didn't want to bother anybody before but now I need some help!
I have a late model Zenith carburetor in my 1967 Cal36 that I bought last year.Previous owner - for 20 years - took care of it and had the carburetor rebuilt 5 years ago.
The engine is running fine when higher RPM - no smoke, steady - but when the throttle is being pushed back toward idle, it would rather stall at 1500 RPM. I have rebuilt and cleaned the carburetor over and over and once managed to have it idle at 700 RPM. I let it idle for long but after I came back from a sail and started the engine again it would do the same as before. Down to 1500 and stall. Since, I've cleaned the fuel tank, I ordered and installed the Moyer inline fuel filter kit, replaced the screen in the sediment bowl....but still no idle?
I am running out of ideas? I would order the new carburetor but I am afraid it might do the same as the cause could be somewhere else? ...but where? Timing, leak around the manifold...? If I can be assured that it is definitely carburetor problem, I would immediately order the new!
Thank you!
