Dianne, there are three pawls in that starter clutch, pushed out by springs behind each one. No lube is required for them. Hopefully the problem is a simple one, like some crud getting in the channels the springs live in. The springs and pawls are relatively easy to find, so no worries if they're not in good shape.

LM, good morning, my friend!

Work continues on the '67 Dream.....

Couldn't get the rotor off with a gear puller but a 16 mm 1.5 pitch bolt pushed it off fine - rollers and plungers fell out on the floor LOL!

There was one missing spring, one broken spring, and one weak spring in the starter clutch so I cleaned and repaired everything with 'junk box' parts - will do a proper rebuild at engine overhaul - and the electric start catches every time now. Kick start still not reliable but I am not pulling the case apart until winter!

Found out that I am not getting any fuel through the petcock since I replaced the internal rubber part. Had to pull the tank again and sort that out. It took 3 tries but seems to be working now.

Had to go into the village for another jerry can of gas and will have a go at firing it up again today or tomorrow.

Had to pull the tank again (a couple of times) and play around with 'the internals' to get the fuel valve working right without leaking and to get the fuel flowing, then deal with a sticky needle valve in the carburetor to get fuel in the bowl.

THEN IT STARTED!

For the first time in gawd-knows how many years it fired right up!
Obviously the right hand seal on the crank shaft is done - it left oil on the floor - but it is running. The compression came up quite a bit after its first run as well.

Wonderful!!

I hope the oil is from the changing of the seal, not from the running engine.

Your bike is beautiful. Someday mine will be too. :-)

Spent a part of the day trying to get the throttle in the '67 Honda Dream to move smoothly and return to idle when the grip is released - didn't happen - not sure why - but did get it to close to a reliable idle position. There just seems to be too much friction in the twist-grip.

Lost a tiny steel ball from the signal light switch when it came apart unexpectedly - had an inexperienced helper who 'bumped' the switch lever while working on the grip. I have a spare hand grip so I will have to steal the ball from it (when I am alone in the shop LOL!)

Spent a LOT of time fiddling with the fuel valve and had to pull the tank for the 100th time! The replacement rubber pieces I got for it swells in contact with gasoline and the valve becomes unmovable! :frown: Dressed the rubber piece down a bit on glass with sandpaper and it seemed better now - works without leaking. If I have any more problems with the valve, I am going to MAKE MY OWN and throw the original in the "restoration box" for someone in the future to deal with LOL!

Also found an electrical problem - battery + post shorting on side cover - and fabricated a battery hold-down strap to fix that.

The bike is coming right along! It starts easily and reliably every time now.

Need to fix the signal lamp switch and replace an oil seal on the crank shaft before a "show & shine" on Sunday.
