Motor cranks good. At idle it runs rough. 2000 rpm it levels out and runs great. If I tilt it too far up gas will run out of carbs.
Any ideas on the low speed miss. I have had carbs checked and mechanic can not find problem
 
Gas running out of carburetor when tilted may be normal.----At idle this motor only runs on the top 2 cylinders I believe.---Bottom 2 kick in over 1800 RPM.---WAs compression test done ?
 
was the link and sync done? Were the carbs rebuilt? Was the accelerator pump checked? Is your Mecanic familiar with the 2+2 design of this motor?
