The parts list does not have Type 0299 so as to identify the proper carb. It is a Toro autochoke with 6.75hp B&S 126T02-0299-b1 10032757. Engine is hunting the first few minutes, then runs ok. I have rebuilt the carb and replaced the governor spring. Am thinking the carb might be the culprit and want to try a cheap new one to see if it fixes the issue. What is the carb model number, or where is it on the carb?
