Hi guys

Im working on rigging up a different cold start and getting rid of the thermowax. I dont feel like holding the throttle down and i want something automatic so i was thinking of using the AWS with a small needle valve or ball valve or even making the input side of the aws smaller so it would only bring the engine up to 1500-2000 rpm. but to do this I need a temperature switch that has continuity from 0-150*F +/-. Our stock temp switch at the bottom of our radiator only goes from 55-66*F. I will try that out but i dont know if that would work.

Also to get rid of the thermowax i was thinking of making some sort of stop plate to go in place of the thermowax to hold that cam screw and adjust it as needed to get a rock sold idle. The thermowax has been screwing up my idle and TPS setting for ever and im sick of it .

So anyways I found a company that makes these switch to what i want they just need to diameter(of threaded part) of the switch and thread pitch. They would then be able to make me some.


Anyone know the diameter and thread pitch? I dont have an extra one to look at and dont want to remove the one i have.


thanks guys
