Alright.. i have tried tofix this twice but it keeps comming off

the rod on the left (controls needle?) keeps comming off.. what are yalls solutions to getting it to stay on?

Not sure if you mean the needle seat screw is coming out or the power valve rod that is on the right. I wouldn't spend a hole lot of time fussing with it period. If you want to keep the monojet, you could probably find a used one cheap and combine the parts to make one along with a rebuild kit. New ones aren't very expensive and almost nothing used.

This might help you a little if you need to find an older one and replace some of the parts.

That's some good info on that link.
Definitely worth reading if your running a monojet.

maybe this will help... it wont stay in there after you push the pedal a couple a times....

ol Curt · 01-26-2009, 02:44 PM

I feel that is a matter of worn parts. I would follow the original suggestion. You could probably find several monojets on ebay for cheap. What year and engine is it from?

Here's several ranging from $5 to $100

well my truck is a 63.. but some guys on another site have been saying its from a newer truck

ol Curt · 01-26-2009, 06:40 PM

I'm not expert enough to tell from the pic you have whether it is a monojet or not. If your truck is a 63 it would have had a Rochester Model B. I have one of those that I think I bought from Advance Auto for a very reasonable price. You could try there. I don't see them on their site, but they aren't hard to find either. I would ask around on the inliners or stovebolt sites. I ended up going with a holley/weber 2bbl

MrPhotographer06 · 01-26-2009, 06:44 PM

will it bolt up to the stock manifold?

i'm also lookin at another truck ... but its not techincally running.. timings off..

ol Curt · 01-26-2009, 11:02 PM

You would need the $15 adaptor plus the $75 carb(rebuilt). Mine ran great with it on there. This would give you an electric choke and the 2bbl is progressive...you are only using one unless you get into the throttle.

Jim Carter used to sell the carbs...you may have to call them. http://www.oldchevytrucks.biz/55_66/full.asp?page=106

ol Curt · 01-26-2009, 11:08 PM

I buy some from these guys, but find them pricey on darn near everything...this price isn't too bad. http://www.lmctruck.com/icatalog/cbe/full.aspx?page=73

HERE YOU GO...SWEET!
