trickedcarbine Posted May 4, 2012 Report Share Posted May 4, 2012 I recently had an issue with my Weisco crank that caused some timing issues, and I would just like to give you fellas a heads up. The issue was that the motor would read 3/4 degrees off at all times at all rpms wich meant my plate at +4 was really +7/8. I checked the electrical components from that build and they seem cool. So after asking around a few reputable builders told me that there have been a few mishaps from Weisco where +4mm cranks had the woodruff keyway machined at the same position as their stock stroke cranks. After being called a "dumb fuck" by a very reputable hq source( Dumbshit/zilla haha) I was compelled to take that crank to a local shop to verify whether this was the case. Sure as shit, the Key way was off. This in turn meant the fly wheel was degreed wrong from top dead center, causing the timing to be at a constant 3/4 degrees off. So, always verify that the pickup coil is dead center on a flywheel pick up point when a piston is at TDC with the plate at zero. This should be checked upon assembly before the head is installed. Big manufacturers do make mistakes and it goes a long way to check every product so that their blunder isnt your headache. Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted May 4, 2012 Author Report Share Posted May 4, 2012 No shit? Im glad you made this post. What are you gonna do about it? Send it back or just work your way around it? I called weisco and they were more then happy to fix me up with an exchange. It apparently used to be a prevalent problem when the 4 mil thing was just starting. That is why older timing plate instructions say to verify actual timing before advancing from zero. That old motor used to have constant detonation issues and I kept pulling timing, compression, and ran really good fuel. Just never was enough, and the crank took a poop on the big bore motor in my Sig. The new crank is going in a set of Passion cylinders, so keeping my fingers crossed.
