I've got a 79 WR250 that won't fire up and I'm trying to diagnose. Original motoplat with large flywheel. Original crankshaft, carb and fresh top end. Bike will not fire at all. Not even a pop. Pulled exhaust thinking plugged P pipe etc-still no fire. Entire ignition gone over by VS and blessed off as giving great spark. Won't fire on bump start down hill. Swapped carb with known good carb still nothing. Ground wires run from stator to coil to cyl head. Will spark a plug laying on cyl fins but won't fire up. Mag timing set to 2mm. Timing pin location is at/near 4 o'clock location. Any help would be appreciated.

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 The previous version was outdated and no longer supported.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!

klotz super techniplate junkie
is the plug wet when installed, kicked, then removed? bike is likely flooded....especially after the pull start didnt work.
A few more pertinent details, carb working fine I e cases not full of fuel, plug getting wet with fuel but in normal fashion i.e. Not flooded with fuel, great compression-new bore and Wiseco piston Assy. I did replace the cases due to case rot and I believe they were from a 78 motor. Can anyone confirm the location of the timing pin as about 4 o'clock for the large diameter motoplat flywheel used on the WR?
