A kind of 'list' of the AM Clone 660 parts that are poor quality compared to OEM like the chain tensioner etc would be helpful for guys doing these builds. Maybe a few OEM parts could really better these builds possibly. From reports do far, the kits seem to be acceptably good. I'm going to do one and use some OEM parts but still use most of the kit.
I guess the point is that the stuff isn't bad. I've pointed out early on the issues I had with chain adjust mechanism, tank cap rubber seals, decomp, and spotty carbs. Those issues were tangible and I suspect most who don't swap them out will eventually do so. I did have issues with the pull start on the first one, a drop of oil fixed that. Nothing but wood chips since.
A suggested upgrade path to close in on factory built saws might be case seals, intake rubber parts (I use OEM pulse lines ), and possibly a better top end but I'm not certain other than OEM what that would be. I like the 56mm versions. Haven't really seen any of the AM 56mm's that impress me enough to move away from the FT. But I have no failures to report on any of these suggestions, its pure speculation based on instinct, look and feel of the parts.
Having said that, mine are all running just fine and haven't given me a reason to swap out anything but those things I mentioned in the first paragraph to this point. When and if they do..... you know there will be an update video.
AND if there are any Huztl/Farmertec folks watching, RAISE the floor of the exhaust port on those 56mm top ends .025in and all free porting issues goes away with metal to spare for those who would like to tweak a bit...and the port STILL will be level with the piston at BDC within a reasonable tolerance. Of course they might already have done so, the last one I've received was in early 2015. Actually this is as much a cosmetic thing as so far none of the FT 56mm top ends I've seen to this point have enough free port to matter. Not the case with some of the other AM outlets with similar looking castings but the issue is real.
