carb spacer question

borrowashboy · Post by **borrowashboy** » Fri Sep 21, 2012 2:52 pm

after much popping and banging i finally traced the fault to the heat insulation spacer between the carb and the head - it was cracked. not having a spare i did a search and found plenty of local shops that sell them, but they all seem to be the 1/8th thick tufnel ones. mine is about 4 times that thickness, so would the thinner one be ok or do i have to have the thick one?
cheers, bb.

Get the correct one, check what pt. no your bike wants and get it from club spares.

The club spares spacer is too long for a lightweight, I bought one and made two out of it, but I could have ordered the wrong one

Ah, yes, sir has noticed all Ades bikes are lightweights, and there 3 different types of spacers, depending on year and carb type. None of which the club seem to stock.
So I suggest you try Amal for a correct spacer, but, have you got the correct carb.
You may be able to just tell Amal the bike details and spacer details like fixing hole centres, bore size and spacer thickness. Maybe give the spacer a good clean, open up the crack a little and araldite it, if it comes down to make do and mend.

I got the correct spacer from Hitchcocks when I rebuilt a Model 14.
I fitted the carb. to the studs and fully engaged the nuts then measured the gap to the inlet flange and was able to select an appropriate thickness of spacer from the Hitchcocks website.

sorted. bought a length of tufnol type sheet and made one myself. fits and works perfectly so for £5 including post i've got enough material to make 5 more as and when. for the sake of an hour bent over the vice it was well worth it.
cheers, bb.
ps, does anybody know the length of the clutch pushrod for the duplex type clutch? i fitted my rebuilt one this morning and the pushrod isn't long enough.

is this still for the lightweight? theres a couple of different rods I see, also a 3/8" dia ball.

Is the ball bearing still in the gearbox end that pushes the rod when the lever moves?
