Some nice guy

[jlaird]

on the Spridget list gifted me with two sets of HS-2 carbs tonite with intake manifolds and heat shelds. Boy what a nice guy. Going to be just the thing when I start doing engine upgrades next year.

Now have carbs, intake manifold, and exhaust manifold. Think I best get a new cam, hehe. Sounds like 12HP to me so far, about the end of the year will start looking for a head. Want to keep the 945 for the present anyway.

i don't know jack ... after reading all your trials and tribs on your carbs, i think i'll just send mine out to joe and have him redo and tune the entire thing. most all things i will tackle on this car with exception of carbs. no matter how simple people say they are.

Awww, Fred... they only have a few things in 'em wot actually move to any degree. As long as the shafts don't need rebushing the rest is straightforward "follow the book" stuff.

...but Joe does do a beautiful job. /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

doc, when it comes to carbs, i seem to have two left thumbs. since this will probably be one of the last rebuilds, i will probably leave it up to joe. the good news is that the carbs i have are in pretty good shape even though they are covered in years of crud. i'm sure joe will set me up nice. i'll be on the road that much sooner.

Have no problem with any carb work but for the machineing stuff. No way. Never trained, never learned. Leave it to the professionals. I have found over the years that the real trick is just knowing what needs to be done.

How come I did not know how sensitive these carbs are to a bit of air leakage. I have run em for lots and lots of years and never a problem. All of a sudden I have it driven home hard.

I think these things are just getting old, Jack. They've got almost 50 years of wear now, that must add up.

The problem is Jack that as things wear we tend to compensate and don't even realize we are doing it ( at least I know I do ) lol

 

[jlaird]

Always thinking. Wonder if the dizzy is off a tooth, don't see how but........ If this carb rebuild does not fix it that's something for me to check. At the present it likes where it is and anything more than about 10 degrees to either side and it will not run. Must be ok.

Carb bodies are in the mail to Joe at this moment.

 

[Trevor Jessie]

Are you asking about the cam timing?

 

[jlaird]

Just commenting Trevor, you know I worry a lot. Had to change it from 180 out and could have done it, but prob not as it runs so well over 1800 rpm or so.

 

[Trevor Jessie]

OK, but what about play in your distributor shaft? If that bushing is badly worn, then your timing might be bouncing a lot at lower rpms.

Just wanted to give you something else to "ponder" while you wait on your carb rebuild. /bcforum/images/%%GRAEMLIN_URL%%/wink.gif

 

[bugimike]

I would think cam timing chain gears alignment as the dizzy itself doesn't have much of an option as to how it fits (ie: drive dog)!

 

[jlaird]

Noop, gears are aligned properly. Heck I also had questions so took it apart and checked, tis ok.

By the way the drive dog gear can be put in any old which way, gota be careful there that's how you get 180 out or any part thereof.

Shaft bushing is very nice so snug I can not feel any strange movement.

Naaaa, it's the carb throttle bushings.

While things were open today ie carbs off I pulled the exhaust and refitted, did not like how it was.
