double roller timing set

Ok i'm replacing the timing set in my 79 mg midget 1500. I'd like to get the best set thats made for this little motor. I'm looking for a double roller set but I can't find one for the 1500. Does anyone know if there is one out there? If not what are your recommendations for the best timing set, race quality.

Just fyi, I'm replacing the timing set as I think mine is worn. When driving the car at about 2700 rpm I here a loud rattling sound from the engine. The rattling stops about 3000rpm but comes back about 4500. I'm also going to replace the camshaft while i'm there.

Any thoughts on the rattling and recommendation on a race quality timing set??? Thanks

A term commonly used to describe all the bits and pieces that go into a timing belt kit. It's a chain motor but I think the OP ment gears, chain, gaskets, and seals

This? Sorry, I grew up around british cars and learned from thai haynes manual etc. I've always known that as a duplex timing chain. http://www.canleyclassics.com/duplex-chain-conversion/

I dont have a 1500, but their company has been mentioned before on teglerizer's website, at least when it comes to updating the rear suspension on a spitfire. If you look at the triumphexp link, some seem to say the timing chain sprockets off a TR6 will fit.

Here, let me make this easy for you, since I have building these engines for decades. Don't ask me why the normal vendors don't educate their customers to this, probably because most of them don't know this. You use a the dual timing chain and gears off a TR6. I never built a 1500 without a dual set up. If you need help with his, and it sounds like you might, I can help you with your engine parts and steer you in the right direction. The deal is the TR6 dual row set ups are a direct bolt on interchange to any of the large journal Triumph Spitfire/MG Midget 4 cylinder , meaning later 1300 Spitfires, and the 1500 engines used in both the Spitfire and MG Midget.

So in closing, it's not a obscure link on the net, or some special part, it's just knowing the parts that interchange, and the ones that don't, and that's what I do every day in very hands-on manner.

Thanks Hap. Its been a few weeks since ive been on the forum. Ive been working on my other project. I'm ready to pull my 1500 out and replace the timing set. I could def use your help for the right parts and fitment. I also want to put a bigger cam in it. I dont know what cam it has now. Not sure if its stock or what. How can I find out what my current cam is, what cam would you recommend for the car. I do want something with a big lopey idle. I dont mind changing the valve springs if i neeed to. This is just a steet car with the occasional track days. My current setup is flat top pistons and a weber 32/36 with 3.90 rear. I will be replacing the weber with dual weber 40's.

Thanks Hap

We ran an A-8 Grind on a full-race TR 1296, It ran like a scalded cat, had a great, flat power band using the big valve head (TKC something or other) and one DCOE 40, I'm not sure that you want to put a PAIR of DCOE40s on it, that's way more carburetion than 1500cc can handle usually.

hello Matt,
I decided to go to a dual timing chain on my 1500 mostly because it sounded cool. I was in the middle of my engine rebuild and my engine guy told me that the gear was worn and the chain was a stretched.

The biggest issue was that there are no alignment marks on my new double-timing chain gears. see:

FWIW, most of the vernier cam gears have no dot on the cam gear, so I use old OEM cam gears, I ahve them for most engines I work on, and lay the new gear on top of them and then transfer to dot to the new cam gear.

Hap,
Its great to know that you have these.

How much of an effort would it be to create and publish a photo reference of these?

Thanks,
Y.

Y, what is it exactly you want a picture of, I done write up on vernier and timing gears, cam timing and many other topics in my rebuild kit vendors ad, I put lots of engine rebuild tips in that thread.
