Guys, Thanks for all the good tips. Good to know to do a serious warmup or nothing at all. Don't think I have a mouse problem and don't want to find out. Going to try lots of decon and maybe set up "nesting box" on the other side of the garage. I have seen this used before and the theory is to try and give them a more appealing place to nest other than the car. Then when it's time to warm up the car you hook the exhaust up to the box......
Just did the 500 mile trip to pick up my winter project, 69 Sprite with a Datsun A12 engine with a 5 speed. Also has a light weight fiberglass early Bugeye hood.
Runs, doesn't stop - $800 with 4 new wheels.
Thanks again
KW
