I have a Canadian 218 in my recently purchased Fargo. Have done a few jobs on it and did a 50 mile round trip in it last weekend. Noticed a bit of blow by so did a leak down test which revealed poor ring seal
Got the pistons out and the bores looked good but it seems I have 3.375" pistons and rings on 3.795" bores. New plus 0.020"pistons are quite expensive and wondered if it would be cheaper to sleeve down to 3.25" or go bigger. It would mean a lot of work but i am open to your comments. Thanks
