Good advice as usual.  And you're right about that brass pulse tube not being on the IPL too.

All of that stuff needs to be looked at closely. Some of it is fine, some not so much. 

its a simple press in fitment

Nikko, we have been having a discussion about possible differences in deck height between various models of the HVA 362/365/371/372 saws. Do you know if there are differences in deck height on these models or are they all the same. I have looked around the internet and on the Husqvarna site and cannot find this type of information.

 A friend and I have built several of the same formula saws. Sometimes you have to use a base gasket to get correct squish and sometimes you can get away with only sealant. I tend to think that the differences are probably in the aftermarket cylinders we are using but there could be design differences in the HVA crankcase deck height across various models in the same family.

I don't believe we were using XT cases in particular, but that could be. In the current set we were both using 365SP cases, using the same jug and piston, Hyway BB 52mm with a Meteor Stihl 064 piston. I had to use a base gasket to get to .020 and Alan got away with no gasket (goo) and he is at somewhere .025-.027 IIRC.

My guess is that the AM jugs are what the difference is. I have two kits on the way and will measure them and post the results.

Thanks Jim, I am looking at the clutch side of a 372 case right now. The tube appears to be z shaped in that the bottom of the z is inserted in the case, then runs to the right a little bit with the remaining leg sticking up. In the one I an looking at there appears to be some sort of bulge under the paint as if the thing were soldered or glued into the case prior to paint being applied.

I will get a couple pictures so everyone can see. I will photograph two examples.
