Hey guys I’m quite young and this bike is my first rebuild and first bike.I know it’s a lot bike for a first but I’ll be fine. More important I fully rebuilt the engine on my 1993 WXC 360 and seem to have a Port Timing issue. I diagnosed it because when cranking engine over by hand it would suck air in but then push air out through my new reeds and pop the whole read holder a little out the intake. I have two Base Gaskets a very thin one and a very thick one. I cannot seem to figure out how to stop this problem. I have a new Woosner piston and cylinder from Powerseal, new boysen reeds and new intake boot with boot mod. I have tried doubling up gaskets and have yet to try the thinnest gasket because I don’t know the squish. Please help me I’m new and this old 2 stroke is kicking my butt.

Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!

Not sure what the problem is. I guess that you do not have the reed assembly bolted in place. the whole concept of the reed assembly is to keep the intake charge from being able to go backwards out of the transfer ports and crankcase. you won't really know whats going on until the intake boot and reed cage is secured to the cylinder.

A reed valve will have pressure against it during a phase of the crank's rotation. It sort of sounds like you think that the pressure against the your reeds is excessive. What makes you think the pressure is excessive?
The squish is the area between the piston and the head when at top dead center, TDC. I don't see how the squish has anything to do with excessive reed valve back pressure. It would be helpful if you could provide the problem thats occurring when the motor is running.
