So I went ahead and changed the vacuum port from ported over to full. As my car doesn't have emissions (no A.I.R system injecting air into the exhaust) according to that article, it means that there's no benefit in running ported, as ported is designed to help keep the spark very close to TDC so that when the exhaust valve opens, the mixture is still on fire and the air being injected helps give a more complete burn. As a result, power is lost and also idle temps are higher. Therefore, I changed to full vacuum and as the article stated, my idle rpm went up, as there was an increase in power.
Didn't notice much of a difference in idle temp, perhaps it took a minute longer to get to operating temp. Then again, I had changed the thermostat out from 160 to 180 so that's skewed the results. The electric fan does come on less frequently now, before it was on and off every 15 seconds. Then again, this could be to do with the thermostat.
Need to check the timing now as i've no idea what it's set to. It does idle nicely and start nicely.
What's a good starting point for timing? Manual shows 4 (or 6) BTDC but that's emissions based. Also, as RPM at idle has now gone up, should i reduce the rpm? It used to be about 550 at idle, ran nice and smooth. After changes, at first it was about 950 but not it's about 850.
Guessing this will also turn into a carb tune? It does run a bit rich (i can still smell unburnt fuel on my clothes
)
