lumpy

[bighed]

Would a kcast1 cam make a 1300S run lumpy?

[tomfromdelmonte]

I reckon it would yep. Just look at stats for it on kent cam website

[bighed]

On tickover?

[dgbnova#1]

Defo would on tickover yes I would think, so it's up and running then

[Scottcooper85]

Do you have vernier pulleys on? If so have they been set up properly. I had cams on a previous nova that wouldn't tick over on it's own at all lol

[bighed]

Yeah. Kent adjustable pulley. I've got the timing spot on off a timing light. It's lumpy on tickover but as soon as I touch the accelerator it revs spot on. Feels underpowered when driving tho

IMHO the ast1 is a fairly light upgrade over std so shouldn't cause too many issues. Perhaps your idle jets aren't quite right along with the base ign timing not being right.

A timing light is for setting ignition timing not cam timing

Who cares about low rpm.

A timing light is for setting ignition timing not cam timing

i know. I was just answering the question then stating what I had done to rule that out.

How is cam timing checked then?

[burgo]

Dial gauge and protractor wheel ideally

It'll be on standard timing marks most likely.... all the AST2's I've seen are on standard timing even after a play on the RR to get more.
