I just got my '70 2.0 6 refired after a long down time. I'm pretty sure I have the timing close, but it doesn't want to idle below 1500 or so, and when I bump the throttle, I don't see anything coming from the accelerator pump in the middle throat on one side. I think the floats are set a little high as well, according to the handy-Dandy little sight tube I bought from our host. My question is, is there one pump that feeds all throats on one bank so I need to look for a blocked passage or something? Just want to know where to start.
Thanks for your help. Jack |

probably a clogged idle jet. try pulling one spark plug lead at a time and see if one does not make a difference. If so then that is the suspect cylinder. Unscrew separate and clean the idle jet.

Yup, one pump per side. If two work and one doesn't you've got a clog AFTER the pump and before the jet. Pull the offending squirter nozzle and blow it out. The image shows what the nozzle looks like and where it goes.

Thanks a lot guys. I'll see what I can find. Hopefully not a mud dauber or something like that.

The image shows what the nozzle looks like and where it goes. (IMG:style_emoticons/default/agree.gif) You might want to soak the squirter nozzles in carb cleaner for a bit. If that doesn't fix it, remove the pump portion and spray carb cleaner through the passages from the pump to the nozzle. My carbs had sat for a long time and I had to completly rebuild them. If you have to remove the pump portion, check the diaphrams and see if they are cracked/need replacing. Don't think dirt daubers are that small to clog that nozzle.... |
