Makita has a 4-stroke concrete saw out so it's only a matter of time till a chainsaw version pops up...

All the new Dolmar trimmers are 4-stroke now.  And, they have the multi-position, run upside down engines available too.

They have the technology developed with 4-stroke handhelds.  I bet they just sit on it with chainsaws until they are forced into using it with environmental laws.

They have an attachment series now with a pole saw and 2yr commercial warranty so they must have faith in them. I haven't had a single problem with the 4 stroke trimmers that we have sold.
This spring they did come out with a 2 stroke trimmer and later this summer they will have a curved shaft 2 stroke trimmer.

Nate, True 4-stroke engine? Or 4-mix variety?

true 4 stroke. amazing part is crankcase only holds 80 or 100ml of oil depending on model. push rod engine with adjustable rockers. single cam lobe that actuates the intake and exhaust valve. I took one home last spring and used it all year and didn't have any trouble with it. they are smooth and quiet. the leaf blowers are 4 stroke too. sell quite a few of the trimmers but cant seem to sell the handheld blowers

I have had a dolmar 4 stroke trimmer for about a year and it is a very smooth, powerful machine. It has the power of a stihl 4mix but much lighter. 245.1? I think?

Only 4 stroke I have tried so far was my old honda mini tiller fg100.  Only thing that was wrong with it was they used a pos hoffco transmission gear case. Never any troubles out of the motor. 
Honda GX31 Four Stroke 31cc. I guess they put that motor on trimmers too.

I also have the mtd 4 stroke in craftsman clothing.  Its dependable and powerful but very heavy and has a very cheap feel to it. it accepts all my cheap attachments though which are good enough for me but as a trimmer it is a back breaker. I haven't ever turned it on it's side which is a no-no on these from what i hear. My dolmar 4 stroke trimmer is a 245.4 not 245.1. just used it and realized I mentioned the wrong number.

The cheap mtd are just splash lubrication so running them on their side isn't good.

The new dolmar's 4 stroke don't care about how they are held. So nothing to worry there.
