Can't get 08 250 to run on both cylinders
I got a 08 250 that didn't run/ was sitting with gas in it for a year or two I cleaned the tank out cleaned the carbs and it fired up but I can't get it to run right I had the carbs apart 10 times now and still only runs on the left cylinder right cyl will only fire every now and then I have good compression on both cylinders and looks like good Sparks at the plugs both carb are opening as I apply throttle vacume seems good I checked the valve clearance exhaust are at .008 and the intakes are at .007 I tryed to swap the coils that didn't do anything I swapped the diaphragms in the carbs that didn't do anything and I put new plugs in it and still can't get it to run right .......any thoughts ?

loosening the drain valve on the RH carb...is fuel present?
Note, a couple ounces will drip if bowl is, in fact, full. Have rags or a catch cup under the carb when performing this. So, fuel reaching RH carb,....yes or no?

What was compression numbers on both cylinders?
What vacuum readings did you get for both? Where was it measured? How did you test for spark? Exactly same for both? What’s voltage at each coil’s supply terminal? |
