</div>
<div>Hi FOT,</div>
<div><br>
</div>
<div>Just put a Kent TR4-7 cam in my TR4; 300 duration. 3 laps at Summit point so far, and past half throttle under load, power cuts and air fuel enrichens to 10.5:1. BUT plugs are white. Was running an RC needle from the old cam, tried RA and not much
improvement. Even when moving adjustment to full lean. The last test session is cancelled, so want to see air a best guess on a needle to try - figure someone must have experience with this cam and SU’s. 11.3:1 compression…. <br>
<br>
Also, just put in a new HD condenser just in case it’s an ignition problem.</div>
<div><br>
</div>
<div>Any ideas or thoughts? Won’t be able to test the condenser until qualifying tomorrow, but air file holding steady at 2500 rpm shows 11.5:1 which seems way rich; old cam would be lean under those conditions.</div>
<div><br>
</div>
<div><br>
</div>
<div>Thanks for any ideas!!</div>
