this is cut and pasted from the mechanic that originally did the tests. how can we get more power. wot only 3800 rpm with 2<br />adults and around 3500 with 5 adults<br />______________________-<br />Our technicians performed a compression check on 4/23/04 and found the following #1 cylinder 145lbs #2 125lbs #3 135lbs #4 145lbs.<br /> <br />Your mechanic is correct to recommend a conversion to electronic ignition it is trouble free, however in my experience a simple yearly inspection of a conventional ignition system prevents most issues and they are fairly trouble free.<br /> <br />Using an additive like restore does have the desired effect and given the realitively good compression I'm certain it would bump up the compresssion several pounds, how ever I doubt you would notice any performance.<br />Our technicians performed a compression check on 4/23/04 and found the following #1 cylinder 145lbs #2 125lbs #3 135lbs #4 145lbs.<br /> <br />Your mechanic is correct to recommend a conversion to electronic ignition it is trouble free, however in my experience a simple yearly inspection of a conventional ignition system prevents most issues and they are fairly trouble free.<br /> <br />Using an additive like restore does have the desired effect and given the realitively good compression I'm certain it would bump up the compresssion several pounds, how ever I doubt you would notice any performance.<br /><br />He wasnt sure on the condensor in the dist and he did not do a recheck once<br />he reset the timing so im not sure. He did suggest to switch to electronic<br />ignition distributor<br /><br />so what do we do next or check next to get the performance
