RE: Super Tigre G3250 Radial Mount
I made a mistake when I mounted mine. I have it on a Sig Suhkio. The engine box has a removable top in the SIG. I put the mount with one screw on top and the two on the bottom. I had to reinforce the engine box because of this. It would flex the center of the firewall down. It may do the same thing putting the two screws on top but it would put the pressure point closer to the edge of the firewall. Instead of at the top in the center.
dwkehoss, If you are using standard fuel line this may be your problem. Use the larger size line. Also buy the next size up brass to go through the stopper on the tank. I also drilled out my clunk and the nipple on the carb. I don't have any trouble with mine since I did all that. I am using a Zinger Pro Series 18x6. The big Tigre pulls hard with this set up.
