Heat riser valve

[silverhawk]

hello all,

Is it necesary to have the heat riser valve hooked up,or can I do something different to do the same effect?

This IS a Lark VIII, right? In the colder Northern climates it is definitely necessary to have the Heat Riser Valve working properly for Carb. warm-up and Automatic Choke operation.

If however you install a modified 2 Brl. Intake manifold and new Edelbrock 4 Brl. like most are doing now because of lack of wear-out type parts for the 2 barrel Stromberg, then you have to block the Carb. choke heat tube and use an electric choke, so it matters LESS. [:0]

The heat riser valve is designed to provide a faster 'warm up until it runs right' mode, especially on those cold weather starts.
If you are only doing fair weather driving, with a well tuned Stude....You can probaly get away without one as long as your choke is working 'primo'.
A lot of people remove the heat riser valve, and block off the heat crossover in the intake manifold (dual exhaust only) to help prevent hot weather 'vapor lock' problems.
Your choice.... You can make it run great either way.

Thanks, I'll just hook it up again 'cause I still have a good carb. StudeRich, what parts of the carb is scarce?

Dylan; thought you had a Silver Hawk and a parts car Lark, your family also has that nice '61 Wagon? [:0] Cool! [^]

Mainly it's just the throttle plate (base), there have not been new ones for many years. I suppose a good Carb. specialist could bronze bush some of them, I have a few worn out ones here.

I have never heard the term "hook it up" used in reference to a heat riser valve. it is a 3/4" spacer with a thermostatic weighted flapper valve inside of it, in between the right manifold and the head pipe. Usually it is either there or not.

Truth be told, if you can restrain yourself from having too much fun with the secondaries on a Edelbrock, they can get better mileage and way better performance than the 2 Brl. [^]

I removed the heatriser and shut off and dismanteled the automatic choke system totally.
Instead of this I connected the gasrod on the carb with a hand choke of a mini Austin 7(cheap).Thru the lighter hole
You can see this as a handthrottle divice
so when starting I give some throttle on the dash and it is set as long as the engine is warming up,it works fine,oly the OD is not working in this situation because of the revs 1000-1500
it is not too cold max -10C and she runs on LPG
some times I have to change to Petrol when it is colder then it does work too.
