    3m 1211 or yamabond

    Use it sparingly! They are machined matched case halves and people tend to put a huge thick bead on the mating surface and all it does is ooze into the cases. Very thin film is all that is needed!

    Casey2552,
    Minor correction: The correct branding is "Three Bond" 1211. The stuff ain't cheap but it works perfectly. Here's a link to a store selling it for 20 bucks plus shipping. Do not use "silicone" gasket maker or some other substitution as the fuel and oil will break it down over time. Yamabond is fine, too and just as expensive. Good luck with your project. Be sure to pressure test (not compression testing) your engine before attaching the carbs. See the how to section for pressure testing. This is very important. There is a great thread on assembly in the How To FAQ section. Here's a link for that, too. http://www.greenhulk.net/forums/showthread.php?t=144536

    1211 is the only think that should be used to seal cases and reed cages. ive had leaks with everything else.

    Did you replace fuel lines also?If not, I'd recommend.Do not use ethanol tainted fuel if possible.I believe it will degrade the Tygon lines if used for fuellines(not the oil lines).Did you rebuild carbs?Read here, most problems start with the carbs or oil lines falling off.

    I did did not rebuild the carbs , if they are in need of rebuild will it just run bad , lean on fuel will be noticed quickly with out causing damage I was thinking ,if they have some sort of problem it will still get oil won't it

    I know I should rebuild them but was hoping they will get through till winter , my financial budget is small just trying to get it goin and hope she runs till end of august I will only run her maybe 20 hours this summer so just hoping to use till then
