Chainsaw Repair

They work pretty well on a 395 but will not work on your 394 unless you buy the factory parts for a 395 intake tract. Around 65-85$. However HLS is out of the conversion kit and his been for about 3 months!

Its not hard to convert a 394 to 395 but some other things need to happen as well.
Apart from the boot connecting carbie to cylinder, you also need the black plastic square bit to fit the 395 boot (to seal behind the cylinder.)
Other alterations are, the 394 throttle cable pokes through a small hole under the carbie, it needs the hole enlarged to let the cable come through and fit into the new arm on the boot. If you simply hook up the cable as is, it will pull off the plastic holder on the butterfly lever as its a little wide to line up straight.
Next problem is the 394 walbro won't work until it is externally pulsed on top and a tube run down onto the cylinder base.
Do these simple things and a conversion can be done for the better, you can also use the Tilly from a 395 which is already externally pulsed. Hope this makes sense as I have converted all my 394 racers to 95's but they all run 56mm  Mahle cylinders.
One last thing on BB kits for the 95, I have tested a few now and the rings are no good, I don't think Caber can supply better quality rings, all kits I tested had ring failures after not many hours work.
