My m20 isn't getting hot

If you're having trouble finding a 32mm wrench try a local bicycle shop. That's where I found mine.

Or, if you're a cheap bastard like me, just use a pair of channel locks.

You can get new Hamburg Tecknik ones on ebay for $40. While their a cheaper brand name, i had one on my last car and i worked very very well.

my M20 runs at 1/4 mark all the time. Both of my last 2 m20 cars did this. These engines are meant to run cool. Itll heat up to half way in traffic, then 1/4 on the highway.
