need help with vj90mlesb

[Mrkoolbreeze]

sure could use some help with this, engine has #2 AND #3 not firing on a cold start up once I get it running after about 30 sec. #2 and #3 start to fire normal and it will run great all day. I can move the primary wires from 1 and 4 to 2 and 3 and they spark just fine so I know the coils are working . Ive tested spark when its warm and have a good blue arc at 7/16 gap. I'm guessing its the power pack but that's just a guess and don't want to just through parts at it and hope some thing sticks. Thanks for any help guys.

well I just checked it again this morning and #2 and #4 were no spark checking with my timing light, got it started and runs rough for 30-40 seconds then it will run great and all spark on all 4. this thing is just random, anybody ever run into a problem like this?

Ok so I replaced the power pack and she fires up perfect now when cold and runs much smoother. just thought I would post my results so some one else might find it of use when searching
