did you check your timing? and all your wires,

NIK90s13 · 05-27-2006, 09:54 PM

Yea timing is a big issue, you have to be sure it is 100%. Is your distrobutor in at #1 on TDC. If you are sure of your timing, check you distrobutor, cap, rotor.

yea im pretty shure about the timing, i brought the motor up on tdc #1 cylinder and wired it from there, it has a new cap and rotor too

Markovich · 05-28-2006, 09:34 AM

was it tdc on exhaust or power?

crashtestdummy · 05-28-2006, 03:22 PM

im pretty shure it was on power, but i'll check again.

either put your finger over the spark pulg hold and have a trustwerthy friend just tap the key over until it pushes your thumb off the hole then stop and put it at tdc then. what might be happen is its sparking on every exhaust.. lol hope you firgure it out

peace
