If the chokes are not in a straight line, someone goofed when they did the setup.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify.

Remove the choke butterfly on the front carb and run the cable to the rear, I've run this setup for years without issue.

I'm hard up on the northern border on the high desert side of the Cascades. I need CHOKE on both! As for the chokes not being in a straight line, they are. On the Rochester's, the choke linkage is perpendicular to the Offenhauser intake manifold. So what I need is a split manual choke system to run BOTH carbs. Is there such a thing??? If not, I will build a "Jerry" rig something. I find it odd that a split cable isn't out there w/o having to build one from scratch!

I had them rebuilt as a pair and de-tuned them with the next size smaller main jets; just so that when at idle; things didn't "load" up. So...when I need choke, I do need it at start up and run at my climate. The bad news is that no-one seems to know where a "split" cable system is available. Good news...I built my own today and it works just fine and my 235 is one happy power plant! It doesn't load up and it responds just as it did when running the stock single carb. system. P.S. I also rebuilt the engine and put in a 3/4 mild cam which may have put new demands on the "breathing"?? ( also w/split exhaust) Thanks for the advice. I'm guilty in not sharing all my "variables".
