Oh goodie!! I am working with another person right now with that pulley. Did you make a spacer for it to work with the crank trigger??

:lol: , Yes I used the type4 spacer thats there (I finished it on a surface grinder/flatten smooth/only removed.010) and I had to also cut backside of pulley for clearance .040-.050(trigger wheel hit outer dia. of pulley :x ), another option would be to make a thicker shim , in my case I couldn't, it would have change my belt alignment , by the way thats a saco pulley , so there's no confusion, in my case though this whole REBUILD has been Custom (not by choice :lol: ) hope this helps Bill D.

It is too bad all the BS posts over the coils a month ago made Lance leave the forums.

There was a couple of posts that claimed Lance was misrepresenting or had posted misinformation about 1 or 2 types of coils he was using or recommended for his systems.... Though posts were rather tame, and if he left the forum, it just means he is not serious about product he sells as he would not respond to the queries or correct the information or try to resolve the issue......

Dont remember where the post were, but I do remember reading it....

Sort of off topic, but I like concept of mounting engine low on engine stand for test runs also outboard stabilizers to keep it from tipping with torque.... I have done something similar, with way engine mounts low on stand... Wish all would embrace concept.....Sort of wish people would forget to try and run engines on "T" shaped stands though....Much prefer a "H" shape base for its wide stable stance...

Thanks Dale, I got the idea after reading a few posts on the samba about engine stands , especially a comment about someones stand
tipping over :( , so I decided to modify mine before the rebuild ,also got bus housing on samba , here's a few pic's , cheers Bill D.

I hope board material is non conductive, if not, me personally would like to see grommets in board where wires go through it....

Are you running an electric vacuum pump, a solenoid for a vacuum pump, or what? Curious about that.
