Not a clutch artist job, but they are good to go.

If you ever crash a model airplane with a chainsaw engine, invariably some of the top fin gets broken. They seem to run better after that? May be too much fin for out in the open on a model airplane anyway?

Nice job on the welding.   I have not done any welding on cylinders myself and will have to try it someday.

Thanks on the welding comments, I'm no pro, but it stays together.  Clean the crap out of it, and I used a spool gun ( mig ) and layed the filler wire in.  Tig would not be a wise choice if you ask me.

 660, interesting on the airplane thing, wonder if the fins are blocking airflow from the prop, or maybe the fuel being used like higher combustion chamber temps?

I think with 60-70 mph wind blowing over a original cylinder makes it run too cool? With about half the top fin broken off around the spark plug, the engine runs better.
After the engine gets all ugly, nothing more seems to ever happen to it?

Just put a welding shop board up today.  Separated it out of the Tool shed.

I ran the 394 today, dual port muffler with a new meteor piston and rings, its a beast, love the saw.  I also ran a 390 that I dual ported, all stock, felt great also.  I did a BB 365 special, but have had nothing but issues with the saw, so I can't compare it yet. It is having fuel issues, its going lean.  the plight of the 365 can be seen in my topic, 365 throtle hanging up.
