k thanks for the replies. i'll take another look in the morn and see where im at. i thought i had it good and tight but tonight when i tried to turn it over slowly by hand without glow plug lighter on it! i noticed a slight bubbling for the thread so i figured it wasnt starting for me due to the loss of compression so i was thinking of using thread sealant to rid the prob and try again. but im not so sure that sealant is a good idea. also im trying to build this on the cheap. and the other problem is the closest rc store to me is in london an hr away...arrgg
