Ross’ 1975 CB750

Sounds like you might have a sticking float. If draining the fuel and refilling made a difference, it could have jostled the float into working properly. Can be maddening.

Fuel level will affect mixture so even if the screws are set the same, the fueling will be off if the float is hanging up and causing the level to be off.

Ya, I’ve been thinking about the float as well.  Gonna borrow James’s clear tube unit again and check periodically and see.

Sounds like electrics are operating as they should.

I've had floats in Mikunis stick along the side of the bowl if the float metal that joins them is bent even a tiny bit.  Don't know if your carbs are set up the same way.

So I played around with the #3 air screw and got it running much better.  Today I borrowed a clear tube tool from James again.  This afternoon I re-checked all of the float bowl levels.  #3 was a bit high so I adjusted the float tang.  I found it’s possible to do it without taking the rack of carbs off of the bike.  It’d be a bi*ch though if you didn’t have it up on a lift.

But man, she’s running really sweet, at least up on the lift. 

Have to wait until end of April to have enough $ for insurance. 

Patience, grasshopper.

Glad to see it's all coming together for you.

I’m sure hoping to get out to Saskatoon this summer, Shawn.  Not sure it’ll happen, but I’d like to visit my extended family, and you and Jen. 

[hardrockminer]

We will likely be in Saskatoon in late August.  Then off to Semans to look for the grave of a lost great grandfather.

Keep us posted, we'll be sure to meet up with you somewhere.

Ok, so after a long long time at the body shop, I finally have the tank and side covers home.  The body shop is recommending that I hold off installing the tank trim, emblems and filler cap until next week.  There are several coats of clear on it and it’s a bit soft.  Don’t want to risk imprints from fingers or cloth.  I’ll have to turn the tank upside down on my bench to install the lower edge trim. 

I’ve gone with Planet Blue Metallic, and it’s really, really nice.

Couldn’t wait until next week.  I put the emblems, lower edge trim, and filler cap on this morning.  Turned out pretty ok.  Had to ream out the badge mount holes and filler cap bracket holes to remove excess paint.  Also had to scrape off a pit of paint from the inside of the filler cap brackets.  A bit too much paint buildup to all the filler cap to slip inside the bracket. 

But all good now.  I put in some fuel and now I’ll wait until the showers let let up later this afternoon to try it out around the neighbourhood.  It’ll be the first ride really.  So far I’ve only run it up and down the lane a few times. 

Fingers crossed.

Sounds like almost a photo opportunity coming up, Ross.....

I’d love to post pics.  But I can’t seem to figure out how to do it on this forum anymore.

Took the Honda out for a toodle around the neighbourhood.  Runs well.  LOUD.  Had to readjust the clutch cable down at the bottom.

Starts and idles down nicely.  I reckon it's running lean.  Lots of popping on deceleration.

But man, is she beautiful.

  Richen it up 10%, the amount of ethanol you are probably running.  True fact.

I have the mixture screws set as per stock at one turn out.  I’ll try a 1/8 turn in and see.  Weather is crap for a while though.
