Does this compession sound right?

99 or 100 motor octane would be plenty for 200lbs cranking compression on an unported motor. I don't believe you really have that much compression. What brand starter do you have in your boat?

It's just the stock starter.

I really don't think I have that much compression. I hope I don't cuz I don't want to run race gas.

It has to be the compression guage. I'll try some more guages tomorrow.

I don't know where you get that. Octane booster will not make race gas out of pump gas, but it will make pump gas useable in a higher compression motor in a pinch.

Yes, the booster will bump the octane to a safer level while it does not give it the properties of racesgas, the reasoning I gave is due to the fact that Octane Boosters can deteriorate the diaphrams and reeds. But hey, what do I know ;)

You said the "fact". Just because you say it doesn't make it a fact and a link to you saying it again doesn't make it a fact either. Your other link doesn't provide any good reason either. Saying that octane boosters contain industrial cleaning solvents shows a lack of understanding about the chemistry of racegas. Race gas(and pump gas too) contains almost exclusively solvents. It's full of benzene, toluene, xylene, pentane, styrene, etc... Adding a small amount of these similar chemicals to pump gas does not cause any more damage to a motor than does regular race fuel. It's true that some of the more exotic race fuels are more likely to swell seals and o-rings. This doesn't apply so much to octane booster. If you read what I said, all I said was that it will allow you to run a higher compression motor safely in a pinch. Like you said, what do you know..........:rolleyes:

whatever charles, you are reading more into what I said.

1. in a pinch, it will work
2. Is it recommended to run octane booster as a substitute for higher octane rules ie AvGas or Race Gas, I have been told No.........
3. Your using the work "FACT" as if I said it WILL, where I used the term saying that it CAN deteriorate the diaphrams and reeds (Carbon specifically) Will it always? I could not tell you for a FACT, I have not done hundreds of hours of testing. Have You??

Happy Turkey Day!

if these are ADA 35cc domes on a stock cyl. you are not at 200 PSI, are you sure these are 35cc? If they are 33cc I will trade you for some 35cc. If they are 35cc domes get another compression ga.

I'm pretty sure they are 35cc domes. I even double checked them before I put them in.

It has to be the guage.
