......Read his thread again, he is having more than a hole shot issue.....That sounds like masking the true problem...... The idle screws are set from the factory and the timing should be no more than *20 on his year model. It worked great from the factory and up untill this point. Why should they be adjusted other than what OMC designed them to be???? I have a modified *60 running around that if you advance the timing anymore than *20 I GURANTEE you will melt it down because of the compression it makes. The highest factory timing I have seen on ANY of the V-4/V-6 *60 is *22 with most later models only being *20. I bet there is a reason they dropped the timing back to *20.
The high speed circuit is not adjustable(unless you replace the jets) and the idle srews should not be adjusted, that is why they put the goop in the heads. You have to beat it out to adjust them. If it does that means it has varnish build up and would need the passages cleaned not adjusted. A idle circuit DOES affect the hole shot but would ususally effect it all the time and would not be just happening after a run. I have seen thing from plugs, too high of float settings, and to eletrical issues. They are alot of simple test THEY can do to help identify the problem. Of course these are MY OPINIONS......
When I worked at Prebul, we had cars come in that someone had removed the cap on the throttle plate set screw and turned it to "mask" the real issue and we would repair what was really wrong. Sometimes it would be a IAC, Carbon build up in the passages, pcm would need to be reset due to battery going dead, bad battery (low voltage affecting the computer), a stopped up PCV valve, and sometime a bad PCM. Sometimes have to replace the throttle body because they damaged it removing the srew cap. This ususally ended up costing them more in the long run.
