Thanks Russ It has an Aisan two-barrel carb with a vacuum opened secondary. I recently rebuilt a 1977 and a 1978 carb. I got both kits from Rock Auto. Note that the kit does not come with choke-pull diaphrams or the secondary-open diaphram. If they are bad, you buy separately. Carbs usually have two choke pull-off diaphrams and they are usually bad. Makes the engine run rich or flood when first started. The pods vary alot and if you need new ones - you need to ID it by photos to be sure. If you want the carb to work right when done with the automatic choke - you need those pods working. A 1980 Huntsmans could be on a 1979 or a 1980 truck. Check the Toyota date tag. Quote Link to comment Share on other sites More sharing options...

zero Posted September 27, 2016 Share Posted September 27, 2016 There are two accelerator pumps and both come in the kit. One is a plunger type and the other a diaphram. The plunger type is near always bad and it is what makes a truck bog down every time you hit the gas. Those pull-off diaphrams are hard to find for some carbs. I suggest you get a vacuum source and test your's. They need to work unless you convert your carb to a manual choke. Quote Link to comment Share on other sites More sharing options...
