I bet that one would run a shorter bar good.

Not a problem. Use a 372 intake boot, cut the ear off and twist is some, so the carb sits level again. There was something with the cable too. I can't remember.

On the air filter elbow.....use one from a 395 or a 272....etc.

A **** load of saws have passed in front of me since this thread started.

Here something I tried not long ago.

Too wide on the uppers really......but a fun saw to run.



Nice. So how did it do?

Randy could you remind me for the 100thteen time what the stuff is you use for base sealer again?    I can never remember.   Maybe if in type here I will have something fall back on. Thanks.

I use Loctite 518.

The parts have to be dead clean......and it needs to cure for 12 hours.

Have you or anyone else tried 515?  similar stuff a bit easier to spread out. That is what echo recommends on some of their crankcases along with threebond.

Anyone know if there is ANY actual differences between the OEM Dolmar 7900 cylinder and the OEM Solo 681 cylinder?

Never checked but there has to be port timing difference IMO.  The stock 681's I ran were so strong and it cant be because of just 1mm more stroke. Just my guess.

I agree add what you said to the fact that you need a 1.5mm spacer to make the NWP BBK Dolmar jug work on the 681. There must be some sort of timing difference!
