I have a 41mm FCR on my stroker motor. Engine was dyno with "the right" jets and produced decent power. but jetting is definitally off. It sputters and surges down low to maybe 1/4 throttle then cleans out. Dyno was ran with this in the test description. fcr carb ocemr #5 182m 48p. But i dont know what the ocemr #5 means, maybe needle clip. I think my pilot may be too lean. but im not sure. quad puts out 52.6HP and 37.5lb-ft tq. not bad but expected the numbers to be more opposite. Dyno sheet to come. but need suggestions on jetting.
