Ok, got my "new" CL350 engine up and running....oil leak fixed at cam chain tentioner....there was only 1/4 a gasket!!! some idiot's..... Anywho, I have a problem, Im using Kinihn slide carbs and It sinply wont idle unless I hold the throttle back a bit. Ive tried all the normal adjustments, am using 117.5 main jets and im at about 4500 feet or so. Ive had to adjust the top cable screws on the carbs till there almost all the way out, so now the idel screw is pointless! The cable adjustment on the throttle is all the way out....what am I doing wrong? It was perfect on my olf SL350 engine, I didnt change a thing, till I learend it would not idle... Ideas? should I go down to 110 main jets? Thanks!
