Adjustable Tappets
I would like to know just how many types/brands there are for adjustable tappets for the Model A/AA Ford engine AND of the few...which one is the best.
I ask this because of an exerience I had. Back in 1984 when I moved to Bakersfield, CA I re-restored my Coupe for a second time. I took my engine to LA to have it redone and the adjustable tappets they put in, in my opinion were great as they had a nice hex nut for which one could adjust. Fast forward to 1995 I had it looked over again and unknown to me until later I find out that all those "good" adjustable tappets were traded out for ones with a very thin hex head and not as easy to adjust. So, are there good ones and bad ones? Thanks. Pluck |

Re: Adjustable Tappets
The ones I am playing with right now are Colony brand - I do believe AER uses them in their engines. They do have a smaller nut that sounds like yours almost. I suppose it is better than the non adjustable type.

Re: Adjustable Tappets
The Colony ones are good. I have used them in over 300 engines. I tried the Chinese ones sold by some vendors- they suck.

Pots are pistons?

Re: Adjustable Tappets
Pots = cylinders, aka jugs

Re: Adjustable Tappets
"nipped up" is Kiwi for a lot of things that go wrong. I'm not sure what happened to Derek's engine but it affected 1 cylinder, so he ran it on 3 cylinders.

Re: Adjustable Tappets
On an engine I used to have, the steering control rod to distributor was bent and it would occassionally rub on the spark plug, causing it to short out.

Re: Adjustable Tappets
I use the double lock style Colony lifters in a couple of my engines . The Colony lifters are good and hold their setting but are more difficult to use . I have good luck with the easier to use self locking type lifters and much prefer them . In other words ,you almost need three arms and three wrenches when adjusting any double lock style lifter .
