I put in on the outside (fender side) which gives it tension to hold the heatriser closed then when I heat it, it loses its tension and falls away from the pin extending from the manifold. Is this correct? anyone got a picture of this spring mounted correctly?

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

I was wondering where you found a spring for your heat riser valve...my 230 needs a new spring ( I have it wired shut for now, but cold weather's a comin'!) I tried NAPA and they didn't have it.

#38225 11/18/2002 5:05 PM | Joined: Jan 2001 Posts: 14 Member | | Member Joined: Jan 2001 Posts: 14 | I tried 3 different springs mounted according to the shop manual and the picture shown above, they actually created tension on the heat riser to hold it in the "apply heat to carb" position and then with heat applied to the spring, the force of the exhaust on the valve would allow it to open and flutter. I gave up after those 3 attempts and went to sears and picked up a collar that would faster to the heat riser shaft. I welded a short piece of metal to the collar and attached the throttle cable to the short piece of metal. now when its cold and I start the truck, I first pull the throttle cable out, engaging the heat riser and push it back in when I reach operating temperature. I did not have a good use for the throttle cable up till that time anyway.
It works for me, thanks for everyones assistance.

I managed to adjust the spring a little by bending the inner tang a little to effectively unwind the tension until the thing worked , but I like your positive cable idea too. | | |
