Topic: 750 newly built 836 running troubles

Sweep, I suggest that you if you have a spare points ignition system and coils fit them and see what happens. If you still have trouble you can be sure that the trouble is nothing to do with the ignition system. Pat

Good idea!  I can use my old points instead of buying a new dyna without being sure, thanks.

Either way I'm starting to think I'm silly for not having installed the Dyna 2000 with the rev limiter so maybe this is a blessing in disguise.  I h8 to spend the dough but I've spent so much already and I'm so close to done.

These carbs are new....I doubt it BUT some of that varnish could screw things up. You can place vacuum caps on the starter nipples to see if the problems lessen or go away

Yes I saw that in another post and I'll try it.

Never ship a crank with the advancer stud in it..

I figured that one was my fault.  I didn't even know it came out at that point.

Its amazing how quickly fuel goes off, my carbs were immaculate when I put them on the bike - I ran the bike on a test tank for a few moments after fitting but didn't drain them afterwards. 6 weeks later I came to run the bike properly with the tank on and found the fuel had turned to syrup in the float bowls.  Lesson learned, I think I'm going to have to strip them off again as its not running as well as it was the first time.

I'm happy to report that the combination tearing down and cleaning the carbs, converting to the Dyna 2000 ignition, and installing new Dyna coils did the trick.  The bike purrs like a kitten better than ever before.  Part of the reason it's purring better is because I never bench synced the carbs and they were pretty badly out of sync.

   I caught this thread a little late, but glad to see you've got it all sorted and running well   You might want to install a small inline filter($1.50) and keep it in place for 1,000 miles or so until you've run enough gas through your tank and carbs to clear out some of that varnish. Running only on choke and dying when using throttle sounds more like clogged jets than anything else. A couple good rides then, bam!...problems, is usually how these things arise. Flowing fuel through a tank and lines that have been sitting for x amount of months while the bike is put together

   Did it once. Never again

The bent timing shaft must be the stud that holds the Dyna ignition rotor

It is and I've bent it back and it's ok now, not contacting anything.  I tried to find a replacement because it came back badly bent with my crankshaft but to no avail.

Yes....that part has been discontinued.

Davidsilverspares had them, even though they are discontinued by US Honda. Cost me about $20 total(including shipping to U.S.)

I ordered and they were out.  The straightness of the shaft doesn't seem to effect they Dyna 2000 as much because it doesn't stick out as far.  And Scondon, thanks for the pointer on the throttle cables because those babies are perfect now.

Excellent!
