Hi just got a cockshutt 540
drove it home about 3km seemed to be running fine except it keep searching for idel up and down revs.
went to change oil later had sludge in oil pan so removed it and cleaned it
Then it sat all winter
Went to start it this year now it won't run without battery, had to clean gas take sediment boul was orange from rust in tank.
Now it will start and idel ok but when under load it backfires seems to run better with chock opened.
So where should I start cleaning the carb?
