Ok,Rob, I'll give it a try
Unrelated to this subject, is it ok to mount the manifold pressure switch on the engine side of the firewall. I'm using a Sam James plenum over the engine, so I don't think the heat under the cowl would be that high except while taxiing. I would like to mount it high on the firewall above the brake fluid resevoir to keep the firewall penatrations to a minimum. Do you see any problem with this or is it to hot under the cowl for that switch
Thanks
