Carby to manifold bolts
Just picked up this Tilly and manifold at a swap meet and notice that the bolts holding the carby on have nuts. My Zenith doesn’t. Did all Tillotson carbs have nuts on the bolts or was this one done out of necessity? How many of you have gone down this path with either type of carb? I ask because one of the threads in my Zenith is weak and I’m going to have to do something about it soon.
(Sorry, the Zenith photo is sideways and I can’t fix it.) Additional edit, 9th April ‘18: My Tillotson is actually a Marvel Schebler. Thanks for the correction, Duke36. Last edited by Hoogah; 04-09-2018 at 12:06 AM. Reason: Factual correction! |

Re: Carby to manifold bolts
Probably out of necessity. The bolt holes probably stripped and this is cheaper than heli-coils.

Re: Carby to manifold bolts
...if the threads are stripped I prefer to use nuts and bolts as helicoiling removes a substantial amount of the remaining metal

Re: Carby to manifold bolts
The Tillotson and Marvels are made of pot metal and the threads strip if one overtightens them. I use helicoils but the nut and bolt method works just as well. I have never had a zenith that had lost it's threads. Jack

That looks like a Marvel carb. in photo 1; ditto other posts.

Re: Carby to manifold bolts
You can 'weld' up the holes using those aluminum type filler rods, using just a propane torch and then drill and re-thread the holes.

Re: Carby to manifold bolts
I take it that the intake is for a RHD car?

Re: Carby to manifold bolts
I agree with those above who said that the thread were stripped so a nut was used. I have the odd one like that and have done LOTS of miles on them. No one has ever noticed but mine is not a car that will ever be judged and I know yours is the same.
If it works, leave it alone and drive on, I say.
